Dr. Mecum has moved to 14350 Whittier Blvd, Suite 305, Whittier, CA. 562-789-5577. There is lots of parking available in the back. Just had my follow up after a colonoscopy. Dr. Mecum explained everything very well and succinctly. He answered all my questions. He's been my doctor for over nearly 15 years. One tip: When you have a colonoscopy (or any other medical procedure), be sure to ask ahead of time for an anesthesiologist that is covered by your policy. The office is a little harried, be a patient patient. read more

I was very disappointed with my experience. I went to see this doctor because I was experiencing significant digestive symptoms, including bloating,constipation, diarrhea, and I specifically wanted to discuss whether SIBO my could be a possible cause. However, without ordering any SIBO testing, I was simply told that it was not SIBO and was advised to follow a Mediterranean diet. I don't want to argue, just let results talk. this doctor is very condescending. read more

Horrible Experience -- Disrespectful Staff and Extremely Poor Front Desk Management I had a very upsetting experience at this clinic today. As a patient seeking medical care, I expected basic professionalism, accurate communication, and respectful treatment. Unfortunately, that was not my experience. Here is exactly what happened: My appointment was scheduled for 10:10 AM. I arrived early at approximately 9:50 AM and completed the check-in process at the front desk. From approximately 9:50 AM to 10:30 AM, I remained quietly in the waiting room. No staff member approached me or informed me of any issue with my appointment or check-in. At approximately 10:30 AM, a female front desk staff member finally called my name. Instead of explaining the delay or apologizing for the wait, she told me, in a blaming manner, that my appointment had already passed and that I was "over an hour late." I was extremely confused and upset because this statement did not match the actual timeline. I had checked in at approximately 9:50 AM for a 10:10 AM appointment. At 10:30 AM, only 40 minutes had passed since I arrived, and only 20 minutes had passed since my scheduled appointment time. I immediately questioned the staff member and explained that my check-in record should show that I arrived at 9:50 AM. I was particularly concerned that the clinic appeared to be attributing the delay to me rather than accurately reviewing its own check-in records. At that point, I no longer felt comfortable proceeding with my appointment. When communication at the front desk is inaccurate and patients are treated in a disrespectful and accusatory manner, it becomes very difficult to have confidence in the overall professionalism of the facility. I left the clinic because I did not feel comfortable entrusting my healthcare to a facility where I felt I was being treated this way. I strongly encourage management to review the check-in records and, if available, security footage from approximately 9:50 AM onward to establish exactly what happened. I believe patients deserve accurate communication, accountability, and basic respect. Based on my experience today, I would not recommend this clinic. read more

My gastro issue is still going on after a year after many many times of visiting the doctor.

The doctor and the front desk were extremely confrontational and disrespectful to patients. The older front desk clerk was dealing with many seniors and spoke to them abruptly and quite cruelly. My personal interaction was highly volatile from an understaffed clerk who was taking it out on me as a new patient. I would steer clear of this place that has obviously been in business a long time. They likely stay in business based off of quantity not quality of care. They seem to be concerned about patient volume not care and they don't care if you know it. The front desk is a representation of the doctor. The doctor should be setting an example. He does not, I've never experienced a doctor not attempt to understand, only to point fingers and blame. read more

Just stay away from this office. You will not get the help you need. All they want is to get you to do a colonoscopy. Because that's how they make their money. My appointment was at 1050am. I didn't see the so call doctor till 1200. They obviously overbook patients. He didn't want or care to know about my issues. Brush aside all my concerns. Just keep pushing for a colonoscopy. Which I already did about a year and a half ago with a clean result. Didnt get an exam. At the end. All he said was "colonoscopy is what i can offer you today" and walked out. The Asian lady at the front is rude and unhelpful. The unwillingness to help or verify insurance deductible is mind-boggling. They insist on charging me the full amount of the visit instead of just make one phone call to my Insurance company to verify my deductible. All they care about is lining their pockets. Stay away. read more

WOW! THIS PLACE IS AN ABSOLUTE JOKE! The asian lady at the front cursed my whole family just because i had a couple of patient questions and was in pain. i think she enjoyed watching me suffer. I was cool calm and professional until she started yelling at me in front of everyone and called me rude. It was so bad that someone in the patient room stood up for me and confronted her On her actions. Now that i have read these reviews i understand...They are definitely doing some type of fraud at this place. I would not trust them with patient care and sensitive or personal information. This place needs to be taken down. I am astonished and saddened that other people have dealt with this. a PATIENTS HEALTH IN not a JOKE. I am traumatized to say the least. beware of this woman. stay away from this dr and his wife. read more

I will never go back to him He is so disconnected from his patients.he said I had fatty liver from a fibroscan.he then ordered blood work.n send me on my way.i had to find a liver specialist who saw the bloodwork n read the scans and said I did not have fatty liver. read more

Lady answering the phones on 5/22/26 at 10am is a nightmare she hangs up on you, puts you on "hold" then hangs up. Pharmacy even tried to call her and she hangs up immediately or places them on hold for a while and then says "I can't help." She will then argue with you when you ask to not be put on hold because we have been trying to contact them for 2 days read more

Super long wait in the office. Dr. Mecum didn't look at my chart which lists many medications, and felt very rushed. He asked me briefly about my symptoms, but when I described how I felt like many things not explicitly GI were potentially related (fatigue, potential auto-immune issues with symptoms like raynaud's), he was dismissive and said "one thing at a time." I felt like he didn't take me seriously. He literally just told me to look at myplate.gov and to eat healthy. (I do.) He also never sent my notes back to my primary care doctor, who referred me. Big waste of time. I had to go back in person to my primary care doctor just to request a second opinion to see someone else. read more

ABSOLUTE NO! Wow the front office worker and dr are totally unprofessional and rude!!! DO NOT GO HERE! So terrible! It was our first time going in and the front worker was being so rude to an elderly man in front of us so I stood up for him since she was just so rude! I asked her to be a little bit more nicer! And she started yelling and the dr came out and told us to leave! Hes like we cant make everyone happy so leave! We are new patients and hes like rather not start off on the wrong foot?! Wtf?! What kind of dr is that?! We didn't even fight or yell! I just asked her to be kind and patient with her patients. What kind of office is this?! No wonder his employees are full of shit and rude! Why work for patients if they are going to be rude and bitter?! Dr here should really go to hell! He needs to work on how to be professional and kind so his employees can learn too! Never in my life met such rude people! The office is also so dirty and stinky! Wish i can give them NO STARS! Or even negative stars! Ill be willing to stand in front of the office to stop from patients to see this terrible dr for the sake of these innocent ppl! They should close down! ABSOLUTE NO!!!! No wonder all the reviews are bad! Do yourself a favor and DO NOT GO HERE!!!! read more

Unfortunately, I encountered the extremely rude receptionist on both of my visits to that clinic. She always had a frown and a reprimanding expression. I don't understand why there are so many criticisms of her online, yet she remains in that position. my medical consultation only lasted two minutes; I will change stay away read more

Office experience -- 0/10. The front desk lady who schedules appointments is extremely rude, unhelpful and disrespectful to patients. She was yelling at me and lecturing me -- unbelievable. She charged me $40 for a "missed" appointment which was completely their fault for not sending the Rx to the pharmacy on time. I kept following up everyday for 2 weeks ahead of the appointment to let them know the meds hadn't reached CVS only to hear "we just sent the prescription to your pharmacy, check again". After letting them know 2 days before the scheduled procedure that the medicine still didn't reach the pharmacy and if we should reschedule the appointment they said they'll call me back to confirm. No calls were ever made to me and the day before the appointment I called them again to follow up and they said we'll have to reschedule because there isn't enough time to prepare and added $40 as penalty for not giving them an advance notice. I called my PCP to report this and request a different referral. While Dr. Mecum is wonderful as a caregiver, his staff is ruining his reputation and name. I will not be going back to him as a patient unless he fires his front desk appointment manager. read more

Everyone complains of the front office and there's a reason. There is one woman that is a complete nightmare of a human. I called and she started in with attitude then has the audacity to push it back onto me when I respond with attitude in kind. I want to know how they can have 30+ reviews about this one rude person and just look the other way while she continues to treat patients like crap. The other people who work there are nice and I'm always nice back but if you are unlucky and get the bad one- I'm sorry for you. Also, If you pay with a card they charge you credit card fees on top of your copay. I had a phone check up after bloodwork on Friday 10/4/24- doctor didn't even mention it, not a 'bloodwork looks good, nothing'. $95 copay plus fees to speak with him for 1 minute (see photo). Called to ask for my records so I can know what's going on with my health which is when I got into it with the front desk meany- she claimed he did tell me because he noted my file. WOW tell me how that happened in less than a minute?! No, he asked who my pcp was and if I was getting my scripts okay- which I haven't been. That's another pain when working with this office. I am purposely budgeting for better insurance next year SOLEY to escape this place. You can bet I'll also be filing massive complaints with my insurance read more

Mecum Robert A Gastroenterologist - My $95 copay plus fees phone call with the doc (1 entire minute) - Gastroenterologist Near Me - Whittier, California

It is very disappointing and frustrating that Dr. Mecum has employees who are extremely unprofessional. He is an amazing doctor, but his staff is horrible. Today I tried to reschedule my appointment because I missed it on Monday due to illness. The Asian Lady began scolding me for missing the appointment and was extremely rude when I requested to speak to the Manager. She indicated that the Manager was not in at work today. I then requested the Manager's Name, but she refused to provide it. I then asked for her name, and she also refused to provide it. She then disconnected the conversation and hung up. This Asian individual should not be working in the health industry as she lacks empathy. read more

One star because zero isn't an option. Appointment at 1120 and at 1120 they tell me they're well over an hour behind. Okay, I'll reschedule. Well if you do we are charging 25 bucks! Why, you can't honor the time or even close. Asian lady snaps, you sit down I helping other customers. No seat to sit down rude lady. This place is a joke and unethical!! read more

I was very apprehensive, but I knew I had to see Dr Mecum. But he was very nice. And Karla, who was my nurse, was amazing. The insurance screwed up (as usual) and she called me several times, as well as my son (my emergency contact) to make sure I didn't start the prep. There are not many people like her in the world. Thank you, Karla. You are an A+ in my book. read more

would like to sincerely thank Jessica for her outstanding support in helping me with my medication. She went above and beyond at every step, always attentive, promptly responding to my calls, and ensuring I felt cared for throughout the entire process. I am truly grateful for her dedication, patience, and kindness--it made a significant difference for me, and I deeply appreciate all that she did. read more

I had a great experience with Dr. Mecum and his staff for my endoscopy. The doctor's follow up was timely, thorough, and friendly. I do not know why there are so many negative reviews here. My experience was positive. read more

Horrible Doctor and staff. I have been waiting 2 and a half hours and still haven't been seen. Doctor and staff do not care about their patients. There are a lot better Gastroenterologist out there. read more

Receptionist is the rudest person I ever came across. I was referred to by my primary doctor there. I had to call and schedule an appt. They asked for the authorization number and asked what type of insurance I had. I gave them the information but they insisted that my insurance had a group. I informed them that I only had straight medi-cal and she stated that all medi-cal has a group and to call my primary care doctor and get that information along with the authorization number and not to call the office until all that information is collected. I already had given the information and me working in the medical field as well knows damn well that they can check on their end for the auth number and check the eligibility through the website. Her professionalism and customer service needs a lot of work. I will not be going back or calling back for that matter. This place needs to be closed down from all the bad reviews it had or hire better staff with better customer service skills and people skill. read more

The nasty , old Asian lady at the front, his wife, needs customer service training. The other staff is nice but she ruins the whole experience. Mecum was nice until the old bag went and said I was being rude to her, when I simply said she had a nasty attitude towards staff and patients. Then he comes out , not knowing what happened and taking her lying word for fact. I ultimately decided that this DEFINITELY not the place for me and cancelled my colonoscopy. He needs to get his head out of his ass and let that old biddy stay home and garden. You cannot possibly be that stupid as a gastroenterologist, to see all these HORRIBLE reviews in regards to her and continue to think it's the patients and staff and not that old battle axe. There was no care quality because I wouldn't let that henpecked jackass touch me with a 10 ft pole. Watch out before coming here. If I could give 0 stars, I would! read more

His receptionist at his office.....she a total joke ......taco bell has better service... She mess with the patients names, rude and unprofessional staff, doesn't look good in your office Mr Robert.....she scream on me???? Really? Remember you getting paid by patients in need...that's your job.....not a favor....Mr Robert.... read more

Strongly recommend avoiding if possible. The other reviews are all true, but I still gave it a chance because my options were limited. But I can confirm, it's bad all around. Probably the worst doctor visit I have ever had. The front office is rude and pushy, and isn't consistent with the instructions I got from the doctor. For example, the doctor told me to give them all the diagnostics, and I even hear him saying that to her. However, she then immediately calls me and says only send the latest lab test results, "I don't want everything". This is very bad and Dr. Mecum needs to be alerted of this. My experience with Dr. Mecum himself was also not great. He is not very good at listening and often mishears or mis-remembers something I said a minute or two ago and I have to correct him. I do think he's a nice guy and seemed pleasant (at least at the beginning) but he seems to be stuck in his own ways if you try to suggest anything, and the rest of the appointment was unproductive for that reason and the communication struggles. What made this experience even worse for me was that I had to wait about 3 weeks to see him for the first time, then we had a pointless time constrained 15-20 minute meeting where he said he needs more information and "could not help me today" and rather than taking it there at the moment as he did with one of the labs, he rushed out and made me schedule another appointment on a specific date 3 months forward. So the total time would be 4 months to a future appointment with zero diagnostics, recommendations, or anything useful for me. I'm sure they are busy and maybe this isn't their fault, but so much more the reason to look elsewhere if you need timely care. read more

The front desk manager was horribly rude. Dr. Mecum was the same or worse. I don't believe they care for patients.

I had my appointment at 8:20am on Wed. After almost 60 hours, they still haven't send the prescription to Rite Aids on Friday afternoon. After called the office, the woman who picked up the phone call at 4:57pm was pretty rude and yell that they are busy and ask me "wait" and hung up the phone. Seriously....? After almost 60 hours, you can't send the prescription out? Either you are very inefficient or you don't even care about patients. If one day you are in pain and need your medicine, I wonder if you'd be ok waiting more than 60 hours. Be healthy Ms Rudeness, make sure you won't need any prescription medicine in your future life! I doubt the prescription will be sent to Rite Aids during the weekend either, so I would still have to wait until after the weekend. read more

Today I had the bad experience of speaking with Jessica the horrible person that picks up the phone and the so call office Manager, I had an appointment 08/27/2024 I called to cancel 08/23/2024. she tells me that I will be charged a $40.00 cancellation fee because they go by "Business hours" I never heard of this, she is nasty terrible customer service, not caring and can barely speak English, Rude and Nasty I read all the reviews here on this office. So rude. I will never be going to this Doctor's I liked the Dr. during the consultation but the office staff is horrible. I would never never recommend this office. read more

Horrible!!! Run as far away from this rude, unprofessional and seemingly "burnt out" doctor. His staff isn't informative, he gets defensive when comments or feedback are given regarding expectations for appointments. He was sooooo incredibly rude I walked out of my appointment. He was extremely condescending, was ok with verbal provocation and was completely out of line. I have NEVER EVER experienced a doctor of his kind. I will be reporting him to the insurance company. He should retire, clearly he's miserable helping people and has become bitter. read more

I came in looking for answers just to come out disappointed. Dr. Mecum literally did not let me explain ANYTHING. He kept interrupting saying I dont need to hear it i have too many patients to see. He made me feel so unheard. How is he even a freaken doctor if he doesnt care to listen to his patients concerns? Its almost like he hates his job. WORST DR EVER. read more

Front office is so rude I was calling to make an appt and just one phone call extremely unprofessional and rude lady yelling at me now that I look at the reviews it wasn't me it was her I don't understand how someone can treat patients like that Dave me some time finding someone els!! read more

We aren't even patients yet, and our initial call to setup an appointment went to . The receptionist is unnecessarily rude. I asked a few questions about the doctor; she refused to answer. I proceeded with trying to make the appointment; after providing all my personal information, name, address, phone and insurance info. She tells me no guests are allowed into the room with the patient. I expressed my concern with needing to have someone with me to help describing my medical issues and remembering things the doctor says. She claims that's the doctors policy. I asked to speak with the office manager and of course that person wasn't available. She abruptly ended the call. A doctor who refuses to have another set of eyes & ears when seeing his patients; isn't a doctor I'd trust. read more

Probably one of the best experiences I've had with a doctor. He went out of his way to attend my mother who arrived very late. Yet he skipped his lunch and stayed over an hour. When I told him I was sorry for arriving late, he said something like it's ok, that happens. I didn't expect him to answer like that but it speaks to the kind of good character he has. He is very personable too. read more

I saw this doctor for two years of nausea and vomiting and never any answers or not even a single prescription. I've tried getting my records for my new doctor. OMG What a nightmare!!! The office staff is completely rude and does not even understand the basic manners. What a waste of time and look what I have suffered all this time with no results. And to be treated so rudely by his staff ! Stay away! read more

I have never had a doctor make me feel so unheard and small. Robert made me feel like the pain and discomfort that I have been feeling for more than 6 MONTHS is normal and a result of my occasional use of Ibuprofen that I take when I am in pain. He started talking to me in a way that I didn't fully understand and when I asked a question he rudely interrupted and said, "I'm not there yet, I'm already answering questions that are not on your referral" and proceeded to not answer the question. The pain I experience was so bad at a point that i went to the ER and the doctors there told me that i would need to do one of the following exams; a colonoscopy or endoscopy. Which led me to he seen by Robert. When he asked what I came in for, I expressed the pain and what I was told by several doctors and he told me that "he is not like other doctors who only want money and would do pointless procedures like endoscopy and colonoscopy and that what i have is normal and a cause of my occasional use of pain killers". I left the office in tears because he was so dismissive and demeaning, I was shocked that I was referred to a "doctor" like this. I left feeling worse than I did coming in. If you are looking for health answers, this is not the place for them. Save yourself a copay. Robert will make you feel stupid and I'm sure you won't get the answers you're looking for. read more

I have been going to Dr. Mecum for years and he is an excellent gastroenterologist BUT because of his RUDE office manager, Jessica that had the audacity to talk over me, tell me she would not help me and then hung up on me, I will have to find another specialist to go to. I really hope Dr. Mecum reads these Yelp reviews as it seems that Jessica is an ongoing issue amongst his other patients. It's very unfortunate that she is the issue for Dr. Mecum to lose patients. read more

This is by far the worst physician office I have ever visited. Please avoid by all means. The worst part of the visit was the Mandarin speaking old female receptionist. She is so rude and unprofessional. I have been to the office couple of times and every time I saw her arguing and yelling at patients. I did not say anything till she started having issues with my mother. My mother simply asked her to repeat something, she then raised her voice and started yelling. She then made things up to the doctor and said my mother was complaining. Since my mother does not speak much English, she just sucked it up. This receptionist has absolutely no integrity, extremely rude and unprofessional. She should first learn how to talk like a human. I am surprised any company would use her as a receptionist and be customer/patient facing. Dr. Robert, you are losing valuable patients because of your employee. In addition, their scheduling system is absolutely ridiculous. They schedule you a time but let you wait for hours. What's the purpose of an appointment then?! read more

i absolutely agree with all the bad and negative review of this Dr. I been seeing him for 5-6 years. His wife Jessica who also the office manager are extremely rude and has a horrible attitude. They always want you to pay first then they see you but they never will refund what you not suppose to pay, even thought Insurance said you have no responsible for the visit, They always just yell, and blame on you. They always right and patient is always wrong. You will never ask them any question, they will yell and shout at you. I strongly not recommend this place, read more

The worst doctor we had to deal with. Does not listen to patients and walks out of the room when we want to ask questions. My aunt was sent to him for the second time for some test because he did some test a year ago he didn't want to do test again does not listen to patient shows up 3 hours late to appointments and tells patients he has no time. If my aunt suffers from something that he could have advised her we will be pressing charges for medical diligence read more

I had an appointment with them 3 months out and was trying to confirm it 2 weeks prior to it. I called the office many times and every time I got a disconnected service message. 3 months waiting for this appointment and their phone was disconnected. This is highly I professional especially when it comes to colonoscopies which are crucial to get at my age. I don't understand why my clinic only uses this place. I ended up requesting another clinic for this service from my insurance and finally got the procedure done. Stay away from this place. read more

The star reviews compelled me to meet Dr. Mecum---as only the brightest, toughest MD's become surgeons. I have a signed release from patient to write this review and was present during appointments. Hi Rocio and his beautiful office ladies who were most caring and considerate over 4 months time. Specialists and surgeons have certain reputations some say nasty/nice. Dr. Mecum was professional, kind and humorous. Though a patient was observed clutching a cell phone in waiting room asking "got my money," comedy while waiting how fun! On the last visit, Dr. Mecum had us laughing before we left with a joke (promised I would not tell!) Vitals taken and family history was discussed. So grateful to observe stellar care over 4 month period of time. As far as the less than perfect reviews---state of a patient experiencing kidney failure is beset with decreased mental acuity. Phenomenal care, thanks Dr. Mecum (he is a surgeon) and saved the patient from impending death, so grateful!
