The best out there! Cares about the patients in more ways than anyone else! She's not your regular doctor. read more

In these reviews, there are various complaints about wait times. They are accurate. If that metric is important in how you select medical professionals, then this is not the doctor for you. If it's more important to have exceptional and thorough medical care, then she's worth the wait. If she's delayed it's because a patient is experiencing a serious medical issue - and she's on top of it making sure they are getting the best care possible. I've been with Dr. Maser for over 10 years, and I'm with her because of the moments WHEN I AM THAT PATIENT - whether it was multiple c-sections or a hysterectomy - she was always there - spending as much time as I needed - with the hospital staff being extra attentive because they know she demands excellence. To me that's worth a few hours wait once a year when things are going well. read more

If you notice all of Karen Maser reviews, they are from several years ago. My experience with her nurse and their overall quality of patient care and service was appalling. First, I had and appointment at 10:30am and by 11am I asked if she would be much longer to which the receptionist said "yes, probably another hour and this is normal for her, she takes time with her patients". Okay - so why not schedule them further apart??? Absolutely no regard or respect for the patient and feel that you should be prepared to wait at lead "one to two hours" - that was a quote. So, I reschedule for a 9am appt and was told to arrive by 8:40am. Once I arrived, no one was at the office and it was locked. Only at 8:55 did an incredibly rude nurse let me in when no communication at all - no greeting, no instruction, no sorry to keep you waiting. Then she disappeared into the back and I was left for 15 minutes. She finally came back and took me in to do vitals. I asked - "Is this normal, because it seems your office has no regard for patient care or communication". To which she said, "well if that is how you feel we should probably not even get started" Seriously!! So rude and absolutely no regard or respect for the patient. DO NOT ENGAGE WITH THE PRACTICE EVER. read more

After going round and round with my PCP and previous OB/GYN, I finally saw Dr. Maser. I knew in advance that I might have to wait so prepared for that reality. Dr. Maser took 30 minutes to meet with me in her office before my exam. She knew I had been in a waiting game with other results and took time to explain everything to me. She is straightforward, no-nonsense and extremely competent...you can tell caring for her patients is her calling. I am so relieved I found her. read more

Horrible! Rude and inconsiderate ! Don't be early for her appointments. She made me wait at least two hours until I saw her. She doesn't return phone calls when I had questions. She has too much on her hands ! Find someone else. ****Warning***** read more

First time ever that i walked out of a doctor's office. I'm sure Dr. Maser is a great doctor, but making a patient wait for over an hour in the examining room by yourself, only to be told when asked how much longer that there's another patient before me. It's appalling!! I'm respectful of her time by being there on time, my expectations are the same. It's just NOT OKAY!! And reading the reviews so far which is pretty much the same, I'm shocked that the scheduling of appointments haven't been fixed. read more

I was one of Dr. Maser's first patients & have followed her to three different practices until she established her own. She DEMANDS excellence from her staff but as far as patient care, I can't express how incredible she is. She saw me through 2 very high risk pregnancies. What I find INCREDIBLE about her is that some years ago, my mother was in ICU at Fairfax & I couldn't get anyone to tell me what was going on and there did not seem to be a doctor heading the team. I was desperate. Being the only doctor I felt comfortable with, I called Dr. Maser. NOT ONLY DID SHE COME IN & TAKE OVER CARE OF MY MOTHER (not a gyn patient) BUT SAW HER THROUGH TO DISCHARGE WHEN WE WERE SURE SHE WOULD NEVER MAKE IT. I will wait all day to have a doctor with that kind of dedication & knowledges& heart. So bring a book & relax. You are getting THE BEST POSSIBLE CARE TO BE FOUND IN THR AREA. I'm am forever grateful to her. read more

Haaah, I don't care, use to irritate me, the wait, I don't even care anymore. I just love her, she down to earth and honest... I bring my phone, work and personal, and watch tv answer emails, etc.. etc.. etc., good docs are hard to find now a days, so when you find someone decent you stick with them. As long as she gives me one hundred percent of her attention when it's my turn, and she always does, we are good!! Her job is stressful as are many of ours, but let's respect the fact that she is doing a good work for future generations, just as many of us do in our respective professions. I think if understood she is an OBGYN we should also understand her priorities may HAVE to shift. If you don't want to wait go to a GYN, this way you won't have to complete with expecting Mom's, new Mom's etc... nuff said read more

I have been a patient of Dr. Maser for last 5 years and she is an amazing Doctor & Surgeon! I have also delivered 4 babies under her care and without her thoroughness I may not have had any of my babies survive! Yes sometimes she runs late but when you get her she will take her time with you and make sure she does not miss a thing! Best advice for if she is running late call before your appt and ask if she is on time it will save you time and any frustration. read more

Dr. Maser is an outstanding physician. One of the best, however, as mentioned, the 1- 3 hour wait is ridiculous. I'm addition, be careful of billing. If you have a "discussion" with Dr. Maser in addition to your exam, you are charged for two visits. I only figured this out after getting calls from her billing department regarding charges that weren't covered by insurance. Annual visits for the past 30 years of my life, and have never been billed for two visits as part of my annual exam until I came to this practice. I've only been seeing her for two years following retirement of my previous doctor, but I won't be returning because of this policy. read more

Yes, you will wait....But, it is so worth the wait! It was frustrating at first, but Dr. Maser saved my life. She ordered the proper tests and a LIFE THREATENING issue was discovered. She is kind, caring, and listens. The time you wait will be re-directed to you in the exam room. I usually catch up on calls/emails in the hallway outside waiting room, and the staff comes to get me. Or bring a book/NETFLIX and decompress. I can not stress enough that Dr. Maser is old school and will HELP you with whatever issue you have. And if it it not her specialty, she will direct you to the best specialist to address your issue. The cream of the crop!!!!!! read more

Dr. Maser and her staff are outstanding. For the first time in years, I believe I have found a doctor that takes her time with me, listens to my concerns and crafts a path forward. Everytime I have been in the office I am astounded by the comprehensive personalized attention that I have received. Not only did Dr. Maser finally diagnose the underlying cause for my issue, she called the other specialist that I needed to see in order to streamline the scheduling process. Then guess what, her staff called to follow up, ensure that I did not have any questions and that I was able to schedule an appointment with the other specialist. I recommend Dr. Maser to all of my friends and feel so fortunate that I am now under her care. Her knowledge and expertise are unparalleled. It is so refreshing to be treated like an individual instead of a number. read more

I find it funny that the people who complain about the long waits claim their time is not being respected when actually, they are not respecting the time of the patients who Dr. Maser is attending. There is a reason why her waits are long AND why she is an excellent doctor. She takes the time to address serious, life-threatening issues with her patients which can cause excessive wait times for other patients. I have been a patient of Maser's for 9 years and have waited several hours on numerous occasions. But do you know why I'm giving her a five star review? Because I know that I will ALWAYS receive excellent care and have two beautiful children to prove this point (both of which may not be here if it wasn't for Maser's expertise and care). If the wait is too long and you don't like it- go somewhere else so the schedule can be cleared for my appointments! But in all seriousness- if you can clear a few hours and have the patience of an adult to see Maser, do so! She is an outstanding obstetrician and gynecologist. In addition, if the office staff is rude it's probably because they are sick and tired of hearing people whine about the wait time when they have no control over it. read more

The Dr may be good. I am not sure if she is discriminating? and doesn't want to see me as I am a Minority not white according to their sheet! This is how deep she has made me feel. How Bad she has made me feel. That I had to question is she discriminating against me this question doesn't easily come to my mind but it did. I walked in at 3:15pm had a 3:30pm appointment. after waiting in the waiting room for an hour i walked up to the front desk and asked how much longer? she was extremely short and rude to me. But did mention there were two ladies that came in late after their appointment so will be seen after me. THIS WAS NOT THE CASE! Last year I remember waiting for 2 hours and she made sure to tell me I was the last person she looked at as pregnant women have a priority. I was okay with that but did not understand why not tell me beforehand to come in later due to delays in the day? This year I waited for 3 and a half hours before I actually walked out. I would love to sue her for discrimination if that is what it is. But if I am not sure I am not an evil person. I will begin some serious research today on her to see how and who she treats this way. There were two white ladies that were late came in after me and I was told they would go in after me. I felt so belittled when I saw this: They got pulled in sooner and even though the staff assured me because they were late they would be seen after me. Yet, I was sitting in the room, waiting for her to come in. I decided to walk around, I walked into the waiting room saw no one there and only one patient in the same room which the DR was in. At that point, it was crystal clear to me the two ladies got seen before me. I took PTO from work. When I had made the appointment I was told it was at 3:30pm. I waited until 6:15pm at which point I walked out. Not only do I find this disrespectful and insulting I am NEVER going back there. The staff is pretty RUDE. Another issue: their phones always have issues and never work or may be again I am given a number that is not the same as everyone else. As, no matter what option I select, I can never reach anyone. She may be a good Doctor but no respect for ppl who are waiting and esp I felt that all the white ladies were seen before me so is she discriminating towards me? I may get a lawyer's input and see how I will proceed. If she is not just doing this to me if it is not a Discrimination then why did the other two ladies go before me when the front desk told me they would go in after me????????? They were both white and one was Pregnant but the other one was not. So even if she is giving priority to Pregnant ladies why did the other one go in before me? VERY DISAPPOINTING EXPERIENCE MESSAGE TO THE DR. LEARN TO RESPECT ALL FEMALES AND THEIR TIMES WE ALL HAVE THINGS GOING ON! Also if you as a Doc are running behind schedule get your staff to call the ppl and tell them to come back two hrs later I asked if I could leave and be back in two hours the Front desk said not unless I want to reschedule for a different day! Since she clearly has no time for me I clearly will never recommend her nor return to her office again! read more

Bottom Line up Front: this is not a clinic that values customer service. If you are okay with rude, unreliable staff and a cold and arrogant doctor, then maybe Dr. Maser's clinic is for you. Otherwise, look somewhere else. We had an appointment with Dr. Maser that she had to cancel because she had a patient in distress. Obviously that was not a problem at all. The staff made us sit and wait, however, for thirty minutes after telling us our appointment was cancelled before they would give us a new appointment. Okay, not great, but forgivable. When rescheduling, the staff told us that we could go get blood drawn at the beginning of our next appointment while we were waiting to see the doctor. Great! A convenience! One hour before our rescheduled appointment, the office called...another emergency. Of course we understood. It bodes well for us that the doctor will reschedule lower priority appointments for an emergency, right? The staff gave my wife two options to reschedule, 1:00 and 3:00 p.m. the next day. My wife said she would call back and called me. I had a meeting that I could not cancel the next day that I would not finish until 1:15. My wife called the clinic back approximately 40 minutes after having spoken with the staff, and was told that they had given away the 3:00 appointment. Really?? After cancelling our appointment twice they could not hold the slot open for even an hour? "Don't worry," the staff told my wife, "the doctor usually runs at least an hour or 90 minutes late for her appointments anyway." Okay, well that is not very encouraging... My wife asked if she could get her blood drawn before seeing the doctor at 1:00 while she waited for me to show up, especially since the doctor would be so late. The staff said that was not possible until after seeing the doctor and denied ever having told us that it was possible even though we had both heard it. I can understand that you need to see the doctor first, but the staff took no responsibility for giving us incorrect information previously. My wife picked me up after the meeting and we raced to the appointment, showing up at the clinic just before 2:00. The doctor came out and told us that she was running behind and it would be a long time before she could see us. She asked why we were late and we explained the situation. We emphasized that we completely understood the need for her to cancel the appointments, but the way her staff handled the rescheduling had left a bad taste in our mouth. And here is the straw that broke the camel's back: Instead of giving any consideration whatsoever to the possibility that her office mishandled the situation, without hesitation and in a belligerent voice, the doctor told us that we should find another clinic. Needless to say, we did. I love my wife too much to subject her to that kind of care. read more

I have been a patient of Dr. Maser's since 2003. She is the absolute best doctor I know, and trust her care 100%. Yes, there is often a long wait, but that's because she's thorough and cares for her patients' health. All doctors are not equal. Dr. Maser is as excellent as they come. She catches things that no other doctor does - I say that, because it's actually happened. I don't care how long I have to sit in her office, because I know I'm getting the best care possible, and that's worth the wait! There's free WiFi, so it's really not bad. Just download a movie or play some games on your cell phone :) read more

Dr. Maser is phenomenal, as is her entire staff! I found out I was pregnant right after my husband and I made plans to relocate for work from northern VA to Pittsburgh, PA, so to say I was stressed is an understatement. Dr. Maser's Office was fantastic and scheduled me immediately for an appointment so I could get as much prenatal care as I could before our move/need to find a new doctor. The entire staff is so caring, thoughtful, and helpful. They went above and beyond for me to get me my medical records, schedule appointments around my crazy schedule, and give me advice over the phone when I had nervous first time mom moments. Dr. Maser is also just unbelievably talented and knowledgeable - I felt like she really cared about us and would've done anything to make sure we had all the information we needed. I got a very protective vibe from her, which made my worries disappear and let me enjoy being pregnant! I'm so disappointed Dr. Maser won't be my doctor anymore and after a terrible experience I just had at a prospective new ob/gyn, I am missing that office even more. I wish I could go back! read more

I have been a patient of Dr. Maser for over 3 years and she has delivered two of my children. I credit her with saving the life of my son. She is very attentive, thorough, highly skilled, and competent. No matter how busy, she always takes the time to truly listen and pay attention to how you're doing. She is also a great advocate for her patients and even checked in on me in the hospital when she was not supposed to be working. She truly cares about her patients and takes the time to provide the best care possible! read more

I agree with many of the other reviewers. One person said she has the long waits because she is saving babies. I have waited in her office for at least 3 hours each time when she has been sitting in her office. Her administrative staff have lost payments and I have had to pay the same bills more than once. She loves to bring in other friends to help her on her operations. I paid for three additional doctors to have my ovaries removed. She wanted me to see a dermatologist for heat rash. She increases her patients costs with all her referrals. I would never go to her again. read more

Wow! So disappointed in the reviews for Dr. Maser. Would you like to know why she may be behind in her scheduling? It is because she is an ob/gyn who is saving lives of babies and mothers who have unscheduled emergencies, which sometimes happen when she has scheduled non-emergent patients. She goes to the hospital every morning to visit her patients and if they have issues she is not leaving until they are resolved. I know this because she saved my baby's life and has done so with many others. Her experience is such that every other doctor at inova contacts her when they cannot figure out what is wrong in their patients. Just talk to the nurses at the Antenatal center or at inova they say she fights for her patients and if you are pregnant and have any issues you will realize it. I had two pregnancies where she was my ob/gyn. During both I had some serious and also some minor complications arise. Complications of some nature come with every pregnancy. She knew the cause and how to deal with every issue. I successfully had two babies four years apart naturally where any other doctor would have done a c-section early so as not to deal with my issues. I went into labor with my second child and she had no reason to come in to the hospital to see me before her day of scheduled appointments began. She came by and saw how many problems I was having and vowed to deliver my baby that morning despite the scheduled appointments she had that morning. How would you feel if your life and that of your baby were on the line and the doctor you had seen for your entire pregnancy passed you off to the "on call" doctor you have never met? She saved my baby's life because of her years of experience in handling my troublesome delivery. I understand a wait time. Some things are worth the wait. I remember moving to N. Virginia and finding out I was pregnant the first time. I took a pregnancy test on the morning we moved here from Georgia. I went to a family doctor to see if the test was right. The doctor herself was 8 months pregnant and since she was just a family doctor she referred me to see an ob/gyn. I asked who was good and without a doubt she gave me Dr. Karen Maser's name. I am not even the only one I know who had their lives touched by Dr. Maser's experience. I referred a friend and his wife to her for their first child. They went on to having three children, all delivered by Dr. Maser. With the third child the mom developed a severe complication and ended up being hospitalized for a week. Dr. Maser knew the early warning signs about her issues and hospitalized her before she became so sick she may not have survived. Maybe if waiting is your biggest issue you need to slow down and figure out what is really important in life....... read more

Ok doctor, I guess... But don't go, unless you are prepared for a 3 hour wait every time you have an appointment. If you have other things to do, stay away read more

Great physician, but be prepared to wait at least one hour (usually more). You will usually spend 2.5-3 hours total. Don't expect a warning. The front desk won't give you a heads up unless you ask and even then you can't trust the information. I wish they would just tell people what time to really show up and keep me from wasting my time. Um yeah---so I have a life and I rather spend my little bit of vacation time on vacation and not sitting in your office. read more

Do not go here if you have any expectation of having your time respected. Dr. Maser and her staff are also extremely dismissive and borderline rude. In the 5+ years I've been her patient, I have ALWAYS waited AT LEAST AN HOUR before being seen. Ridiculous, I know. She is also extremely non-responsive to phone calls and messages, as is her staff. The straw that broke the camel's back: I have a medical issue that affects my gynecological function. Dr. Maser has always known this. Yet, the last time I saw her, she basically blamed me (correction: yelled at me) because she wasn't properly managing it with the correct medications and appropriate referrals to specialists. Imagine that. She also blamed me the last time I saw her for complaining about the wait. According to Dr. Maser, it was my fault and my problem that her (obviously more important) other patients had more serious issues that needed to be addressed and that's why it was perfectly fine for her to waste my time waiting on her to finish up with her VIP patients. OK. After that very unpleasant visit, she ordered a series of tests for me, which I scheduled and underwent. Do you think she or her staff called me to provide the results? Nope. Do you think I got any sort of notice in the mail with the results? Nothing. And, you probably already know what happened when I called to ask about my results, right? According to Dr. Maser (and her rude receptionist): It's all my fault, her staff is so great, I'm a bad patient, yada, yada, yada. I'm so done with this practice. Dr. Maser is a very smart and capable physician, but her poor time management and inability to manage her schedule or her staff processes, not to mention her rude demeanor just isn't worth it. read more

Great doctor, the worst of the worst front desk. I' ve been seeing Dr. Maser for many years, now I have to find other OB doctor, because her front desk is getting worse and worse, unprofessional with no manners. You can't trust them give you any right information, once you question them, they treat you like an idiot. read more

Her 3 hour wait time at EVERY visit shows a blatant disregard and disrespect for her patients. I've been to some top physicians in the country and NEVER experienced wait times like this. As you can guess, I've found a wonderful ob gyn who values me as a human being. read more

an incompetent person: a person who is not having or showing the necessary skills to do something successfully. Can not process fast enough that's why it takes a long time to finish each patient. Don't be fool by these her office staff reviews. Dig deep, Get your facts right. But the best find another doctor who can save you and your baby. read more

Dr. Maser is a fantastic physician! I had two high risk pregnancies with her, both times resulting in emergency C-sections, and she safely delivered my babies each time. In the second case, she literally saved my life and the life of my little boy. She's caring, compassionate, and a great surgeon. I can't imagine going through my pregnancy experiences with any other doctor! read more

Wake up people! 8 out of 10 of her patients end up bleeding excessively for her poor skills. She cannot do surgery. She is not good surgeon. Please save your love one. save your baby. choose another doctor. only good personality will not save life. read more

If you're looking for a physician who will get you in and out quickly and treat you like cattle (as it seems some of the reviewers here want), then Dr Maser is not for you. On the other hand, if you want a physician who truly cares about her patients, takes the time to understand what's happening in all areas of your health and puts your health needs above all else (and you understand that this might mean you have to wait an hour or two if she has an emergency), you would be lucky to get in to Dr. Maser's practice. I wish all doctors were as dedicated and brilliant as she is. read more

If you are looking for a doctor who cares about you and your baby Dr. Maser is your doctor. People who are concerned about wait times in her office, have never dealt with a complicated pregnancy... I owe her my life, because without her I never would have had my healthy daughter today. read more

I have to agree with Jennifer K and Joan A about the admin staff/front desk. I had a new patient appointment this morning and I had to walk out without seeing the doctor. I was, apparently, the 2nd patient this morning who came in with insurance they don't accept - and my issue was completely on their end even though the receptionist tried to blame this on me! I had checked my insurance's network and Dr. Maser is listed as an in-network doctor. The receptionist told me that they always follow a "script" when they are interviewing a new patient and ALWAYS ask if the insurance is a PPO or HMO (which they don't take). I know they never asked me this question as I know that my insurance is a PPO. I don't know why Dr. Maser is still listed as in-network for my insurance; that's probably a screw up by her front desk as well. I wasted a lot of time...phone interview, online new patient paperwork, driving 25 miles to get to my appointment. Terrible customer service. read more

I switched to Dr. Maser when I was 22 weeks pregnant. I moved from a large OB/GYN practice in the area. I felt like a number and never felt I was treated as an individual. The doctors would be backing out the door as I was trying to ask a question. That all changed when I met Dr. Maser. She couldn't have been more attentive. I know she is a very busy woman but I never felt rushed with her. When she was with me, her entire attention was focused on me and my new baby. As a relatively anxious person, this was such a reassuring experience. You may read in other reviews that the wait time is long. Sometimes it was and other times it wasn't at all. But if I had to wait, it was all worth it. I know I got the best possible care from her. Some doctors act like they care for you, but Dr. Maser really does. When she delivered my healthy baby girl I could see how happy she was as well. I can't recommend her enough. read more

Dr Maser is an outstanding doctor. Others have complained that she has long wait times and poor front office staff. I can tell you for a fact that she is often late in her appointments because she takes the proper time and interest that a doctor should take when treating their patients. I would wait as long as necessary to talk to a doctor who spends time with me to understand my concerns and treat my condition right the first time. I have been doctor Masers patient for many years and trust her with my life. Because she took the time in my appointments to make me understand my condition and be proactive, she saved me from what could have been a future cancer diagnosis. She called me in the evenings and on weekends to check that I was doing what was necessary for my health. Ask yourself, when was the last time a doctor called you on the weekend to check that you were ok? I would give anything to get proper care, even a few more hours out of my day to see a doctor that really takes her role as my doctor seriously. Karen Maser is that doctor and you would be lucky to say that she is your doctor. read more
