I am very disappointed with Dr. Aszterbaum and her office staff. As a patient you should never feel as if your doctor is not compassionate to your concerns. A year ago I was having surgery and I was told to go off my hormones and I was concerned about it because I had read that it's not good to go off the hormones abruptly. I reached out to the office staff asking to talk to the doctor on the phone. I was never given a phone call. I messaged the office staff again and I got a message back from the doctor only saying it's OK to go off the hormones. I told her I had lots of questions and I wanted to talk to her but apparently she didn't have the time of day to call me. I ended up going off my hormones for my surgery and started having really bad symptoms. When I went to my appointment a couple months later and told her I was having these symptoms, she said I should've gone back on my hormones which they never told me to do. The following year I started bleeding, which is not good when you are post menopause. Again I called the doctors office asking if I could get an appointment. They said they would have somebody call me back. I even sent a message through the portal. I never received a phone call back. I got a message on the portal asking if I had missed a dose of my progesterone and when I reply back no I hadn't, I never got any more messages. This is not good Customer Service. I was really scared about the things that were going on with me and the fact that they didn't take the time to address. My concerns tells me that they are in this only for the business. There's no empathy or concern for her patients. I would never recommend this Dr to anybody . read more

Two stars for the office NEVER ANSWERING THE PHONE. I have called 7 times to have my prescription sent in. I have to wait on hold 10-20 minutes to leave a voicemail for the nurse. Everytime I call I have to call 3 times just to choose an option bc I get put on hold from the automated voice answering. It's crazy I now have to drive down to the office being that I'm a mom with 3 kids just to talk to someone. I've even left voice mails with all my prescription information and nothing has been sent in! Monica is an amazing doctor. But part of quality care is answering the phone when a client needs you. It's been 2 weeks I've been trying to get ahold of someone. I'm so desperate now I'm leaving this review. Please call me back someone! read more

Absolute nightmare being on hold in excess of 30-40mins. Dr is nice and everything but calling back and reaching someone on the phone is very, very difficult. read more

After being called to the back office an hour after my appointment time had come and gone, I still had to wait another 20 minutes or so before seeing anyone. Then, the MD came in with not one, but two other people and informed me that they were going to be taking her dictation. I was not asked of this was ok and it was not presented as an option. To make matters worse, the document of my symptoms, their duration and when they became worse was false. Topping it all off was to reach back out with if they persisted or got worse despite the fact that I'd been struggling with them for over a year. read more

The WORST customer service, the lack of communication is STAGGERING. An hour on hold every time I call to just to be able to leave a message. The office does not return phone calls. Messages in the HOAG Epic app go unanswered. I'm truly disgusted with this Doctor and the office. I have important questions about my progesterone and estradiol. read more

GOT MY GROOVE BACK. Menopause was confronting and produced so many whacky symptoms, thoughts, and feelings of hopelessness. With Dr. A's hormone therapy, I'm feeling like myself again, thinking clearly, losing weight, hair becoming shiny again, skin feeling supple again, etc. My husband might be as happy with Dr. A as I am. (smile) She's a godsend!! (See old reviews below for more details.) L F. 0353 1/21/2014 LOVE Dr. Aszterbaum! And let's face it, gynecological matters can be highly sensitive - physically, emotionally, hormonally and in many more ways. I just left her office and realized I've been seeing her for 22 years, and I couldn't be happier with another doc, so I'm finally yelping. How delightful to find such positive reviews on yelp for Dr. A because gynecology is such delicate stuff. COMPETENCE, EMPATHY AND TRUST - Throughout the years, Dr. A has never steered me wrong or left me feeling unsettled about my health and what's happening - despite my ups and downs - and I've had my challenges. I seek to understand what's going on, and she patiently and wisely educates me year after year. I have trust that I'm in great hands. Her bedside manner is professional yet with high sensitivity. What could be more important than trust, especially with something so intimate as gynecology? INSURANCE - Throughout my career, I've had 6-7 different insurance carriers and even no insurance for a while - Dr. A's office has always found a way to work with me. I now purchase my family's insurance based on what her office takes. After all, I probably wouldn't be a mother without her help. That's how important she has become to me. She's a genius, an angel and a rock star. My husband and I feel eternally grateful that Dr. Aszterbaum is my doc. read more

over 40 minute wait times, for them to hang up on you. go somewhere else, do not waste your time, extrememly unprofessional

Doesn't seem to have much knowledge about hormone imbalance and its symptoms. She started walking out of the room in the middle of the conversation and I felt rushed. read more

Dr Aszterbaum has been my doctor for 31 years. She is very detailed and thorough. She had delivered my baby, and taken great care of me through peri menopause and now menopause. She is very thoughtful and caring. She also diagnosed my early stage osteoporosis which allowed me to get it addressed immediately. Dr Aszterbaum is the best! I love her new office near Hoag at 510 Superior, NB. It's much nicer than the previous Irvine office. read more

Best gynecologist I've ever been to and I'm 61 so I've been to quite a few in my life. She is caring and understanding and is great at the regular medical stuff plus the alternative treatments. read more

I came to this "doctor", and was barely given a the time to speak, ask questions or garner more information from her before I was shuffled out of the office. The doctor told me I was 100% fine. Well, a month went by, and the office never once called to review my labwork, or discuss the results. I had to call this "doctor's" office several times to get through, then push them for results that they completely forgot about. The labs were not 100% fine, and they provided zero follow up for a serious issue. This office is just another in a long line of medical businesses trying their best to be a business first, while providing care last. You better believe they collect the copay right away, and file your insurance claims with all manner of additional CPTs added to squeeze your insurance for everything it offers. Care is poor, staff is negligent, and the doctor is FRIGID. Good luck, the medical industry is full of aged trust fund kids whose parents just wanted an MD behind their name. read more

THe BEST... She takes her time to explain everything and go over options to keep me healthy and happy

Dr. A performed surgery which went well, she provided excellent care and followed up beyond my expectation.

Dr. Aszterbaum is a good communicator. She is empathetic and make patients feel cared for. Her office is organized and staff is conscientious. Dr. Aszterbaum takes her patients health seriously and she will advocate for them. I have been a patient for more than 12 years and I have followed her to her awesome new location at Hoag. read more

Having just moved to the area I hit the jackpot being referred to Dr. Aszterbaum as an OBGYN. At 52 years old, that alone needs a specialist and she clicks all the boxes: good communication, empathetic, active listener, shows compassion, and is proactive about menopause. I must say I am surprised by the negative comments, but maybe the Office is reading and making changes because of them. The front office was kind and was trying hard at good customer service. They have been taken over by Memorial Care so maybe that is a good thing and they are moving to a new office. Personally, Dr. Aszterbaum impressed me by being proactive and exploratory, really trying to see who her new patient is. I will send my daughters to her because she is kind and clearly very good at what she does. read more

Dr Aszterbaum is fantastic and diagnosed me immediately with menopause and provided a swift treatment of pellet hormones. She heard my concerns and addressed them immediately. read more

I REALLY liked Dr. Aszterbaum. 'Had my first appointment with her today and she was knowledgeable, friendly, compassionate, and at one point funny. She wasn't in a hurry and talked me through my condition, gave helpful recommendations, and sent me home with literature to read. Her office staff was nice and very efficient. read more

Dr Monica Aszterbaum is a very caring, knowledgeable doctor. I have been going to her for 35 years. Recently she moved her office to 510 Superior Suite 200D in Newport Beach (949)763-3106 My friends and I will follow her to her new office! She's the best read more

Dr Aszterbaum has been a god sent! I just moved to the area and trusted another Dr who had a 5 star review on many websites to continue doing my HRT, which I have been having for 5 years without a problem. This other Dr completely destroyed my hormones by lowering my testosterone and upping my estrogen. This brought on weight gain and I have been in excruciating joint pain since. I eat a clean diet and workout everyday, no reason for this other than the change in hormones. Dr Aszterbaum came into her room and listened to me and has changed everything around! Everyday I feel better and better! Dr Aszterbaum should be a 5 star review, she is amazing and I feel blessed to have found her. read more

The worst ob/gyn ever! Very negligent, not responsive,she only cares about money. I came to her office to check my breast. (I was scared that I may have cancer). She checked my breast and after 5 min she said I'm good which it wasn't true! I went for a second opinion to confirm her diagnosis and it came out that I had an infection due to my pierced nipples. Please avoid her as much as you can. There are much better doctors in the area. I would never trust her. read more

I've been seeing Dr. Aszterbaum for at least 15 years (maybe longer). I look forward to seeing her once a year for my annual. I find her to be a warm and friendly person. She has been conservative in my treatment of fibroid tumors over the years and has been understanding of my desire to avoid a hysterectomy. I'm now 62 and my fibroids have been shrinking under her care. I highly recommend her. read more

I saw doctor Aszterbaum one time for a consultation and she was so caring and so compassionate I can't even say enough about her. She made me feel important and addressed all my concerns. read more

Several times over the past three years as a client I have called to make or change an appointment and had to wait a minimum of a half hour to over an hour to get anyone on the phone. This is been an ongoing problem and I've mentioned it before but they've done nothing to correct it. I even referred someone there and mentioned to expect the long phone waiting game and she decided to go elsewhere when she called to change her appt. and was on hold for over an hour. This is ridiculous for any business! I've also had an appointment which they called and canceled with me two days ahead of time because of a nurse not being in that day (this appointment was made the year prior). STAY AWAY IF YOU VALUE YOUR TIME BECAUSE THEY DON'T!!! read more

Dr Aszterbaum was my OBGYN years ago. I was misdiagnosed on a simple condition that ANY gynecologist would be able to diagnose properly. I would not recommend her. read more

I had an apt yesterday that started out a little rough (long wait time and misinformed by front desk staff on the type of apt they booked me for). When I met Dr. Aszterbaum, she was so sweet, very apologetic and took all of my feelings and frustration into consideration and fixed the problem. She was professional and compassionate. I will go back to her for further needs! read more

Dr. Aszterbaum is the most caring and competent doctor. She is so friendly and makes you feel important. I have gone to her for about 25 years and now my daughter is seeing her. She recently moved to 510 Superior Ave, St 200B, Newport Beach read more

She's an amazing doctor. Just moved practice. I am so devoted, I tracked her down rather than change providers. New office number at Hoag: (949) 763-3106 read more

Dr. Aszterbaum is the most comforting, amazing, knowledgeable gynecologist I have been to. I recommend her to all of my friends and family.

THIS DOCTOR IS AFTER YOUR MONEY. I had an appointment to have an ultrasound done because I have a history of fibroid tumors. She refused to do the ultrasound on the same visit and she didn't do a thorough physical inspection. Yet she concluded I didn't have a fibroid. Instead she said I should have a colonoscopy. She did her best to minimize any time diagnosing me so she could schedule another office visit and billed me again. What a waste of time. read more

I have been seeing Dr. Aszterbaum for 25+ years now. I have ALWAYS experienced her caring attitude, knowledge and professionalism! She is the best of the best and truly a gift to medicine. She recently moved to a new office and I am beyond thrilled to have "tracked" her down. She has helped me in so many ways and I am forever grateful to her and her staff. read more

Very bad experience with this place and the doctor in July 2016. Her nurse was great, I loved her. The doctor did have a five minute chat with me in her office prior to the exam, but it felt very Stepford Wives. She's a Stepford Wife kind of doctor, in my opinion. The exam part was the creepiest feeling in the world. I was near having an anxiety attack until the nurse came back in and held my hand (told you she was great). Some time later, I received a call from a stranger saying I had an abnormal test result; I was like wait who are you and why is the doctor or nurse not calling with this information. I told the caller (can't recall her name) I would call back. Very difficult to get hold of and wasn't "allowed" to speak with the nurse or the doctor. The caller proceeded to tell me something that the doctor or her nurse should have called with, especially considering the sensitive information. I told her I would see another doctor because I was so traumatized with the way they did things. A couple days ago I receive a letter in the mail from the office that is typical business speak for "make another appointment." The letter wasn't even signed. This is not the way to conduct business, especially as a women's doctor. There are just too many other options/doctors out there. read more

Monica Aszterbaum is the most warm, kind, reassuring and empathetic doctor I have ever had the pleasure of going to. She truly takes care of you on and is extremely trustworthy on top of it all. Her advice and knowledge of the medical field is top of the line. read more

Love Dr Aszterbaum! She is a lovely and understanding on/gyn doctor. I'm so happy I was referred to her by Dr Stanley Wasbin that I now have my daughter seeing her as well. She takes her time to understand your healthcare background and I appreciate the non-rush through manner. Thanks for being a great doctor I feel comfortable visiting and knowing the thoroughness approach you take to diagnose when necessary. It's appreciated! read more

Dr Aszterbaum was absolutely amazing. (Although, I think she was 30 minutes behind sched) She made me feel she had all the time in the world to answer all my questions, tell me step by step of what she was going to do, she was calm and thorough. I didn't feel rushed, I didn't feel awkward, I didn't feel uncomfortable; she is an amazing doctor. She is a very busy busy and popular doctor so book in advance. btw The staff in the main office behind the desk were absolutely amazing. I think 6 people walked in at the same time with different questions and comments and whereabouts and they hustled with the utmost professionalism. No attitude, and with smiles. The lady with the sketchers shape up, i give her super kudos. Thank you Dr. Aszterbaum for a pleasant appointment. Thank you nurse with shape-up shoes for your professionalism. read more

I was referred to Dr. Aszterbaum approximately 20 years ago...and I've been going back ever since. She is just great. I've never had any problems other than an occasional wait at the office. She makes you feel very comfortable and seems to really care about her patients. You can take all the time you need with her and not feel rushed during your visit at all. I have referred several family and friends to her over the years and they all agree as well. Last year, Dr. Aszterbaum performed a pretty major (in-patient) surgery and my results could not have been better...I was up an about that same evening and the next morning I was able to leave the hospital early. I can't imagine having any other doctor perform the surgery...I couldn't have had a better experience. read more

Dr. Aszterbaum has been my gynecologist for 10 years and I literally just chose my insurance plan to ensure that she could remain so! She is the most competent, caring, thorough doctor I have ever encountered! Rarely does one find a doctor who proactively follows up on routine procedures but she does! My daughter is now 16 and I am so thankful to have the BEST doctor for her going forward! Thank you, Dr. Aszterbaum, for taking excellent care of us! read more

I love Dr. Aszterbaum, She makes me feel so comfortable in a uncomfortable situation. She is so kind and explains things wonderfully! She is awesome! read more

Called their office and asked if any of their doctors are hormone specialist. Sure enough, I was told Aszterbaum is the one to see she is an expert. Day of the visit, no copay collected. I spent 5 minutes in her office to explain the symptoms and my history, she flat out told me she can't help as she herself is in the same situation. Some women have no issues with simple hormones and are well for years some like her and I are difficult. She gave me another doctor name Judy Wei that she herself is planning to see, but due to the cost, she is avoiding so far. Her office charged the insurance and expected me to pay copay! I explained to the robotic office manager why I don't believe the $30 copay is fair, not because it is high because I spent 5 min and it took me longer and more money to come and be told she is really not an expert in hormone therapy! The office manager response, the doctor in her chart has written 30 minutes' time she spent with you and the insurance charges are approved and it is your responsibility for the copay. Not even, an apology for misguiding and representing a doctor who just delivers babies and not an expert in hormone therapy. If she can't help herself obviously she can't help others. Unethical, thieves, and liars. read more

Dr. Monica Aszterbaum takes the time to listen and answer your questions, she friendly and extremely knowledgeable. I highly recommend her.
