Abraham Chen, DO

My primary care doctor is pretty awesome. His front staff could be more friendly but hey I get it … It’s not easy working at a doctor’s office. The amount of BS you have to go through from answering patient phone calls to authorizations and referrals … Then dealing with insurance companies. Yeah I wouldn’t be all smiles and sunshine all the time either. Lol.
His medical assistants staff are great. They answer phone calls or returns phone calls promptly. Being that I’m also in the medical field, I appreciate their knowledge and show of compassion to other patients.
The waiting room could be a little bit bigger though. Or maybe not to double book the doctor so patients aren’t complaining about the long wait.
Dr. Chen is amazing. He talks to you in plain English. Once in awhile he’ll throw in medical terms but it’s easy to understand. He’s approachable, takes his time and answered all my questions.
I’m sticking with this doc for sure! :)

As much as I hate to have to downgrade my rating, my experiences lately have been less than positive. The wait is always SO LONG. Several times I have heard the receptionist on the phone telling patients she can «squeeze them in by double booking them, but they might have to wait». That’s great if that patient doesn’t mind waiting, but now you’re forcing everyone who has an appt after that to wait too. Not fair. Last time I went for a simple Tdap shot. My appt was at 11 and I was given my shot at 11:50. This is completely unacceptable in my opinion, and I didn’t even get an apology for the wait. I can find much better things to do with my time, so we will not be returning to this office.

My husband and I were referred to Dr. Chen by a friend from my work whose been going to Dr. Chen for about 12 years.
His office is located in the Rancho San Antonio Medical Center. You can park at the main Urgent Care entrance where the pharmacy is. Once you enter the doors, turn right and his office is down the hall.
My husband has been to see him a few times, but I haven’t had a need to visit the doctor until yesterday. I was exercising and my ankle popped leaving it swollen and bruised. I definitely tore something. I made an appointment was told to come in at 9:45AM to fill out paperwork. I was brought into the back at 10:00AM to get weighed and have my blood pressure taken.
The huge negative right now is the wait time. I waited alone in the exam room from 10:05 — 10:55AM (50 minutes). I was hoping to get out of there by 10:50AM because I had a meeting to go to for work, I texted my coworker at 10:30AM saying that I was probably going to be late, but ended up missing the meeting entirely. There was an article posted in the exam room about why patients wait so long for doctors so you can tell this must be common in this office. I was finally out of there around 11:30AM.
Dr. Chen is pretty down to Earth and good at explaining things to you, but next time I make an appointment. I’ll have to prepare myself to being here for about 1.5−2 hours. However, my husband seems to have better luck. When he went to urgent care there was no doctor there yet (she was stuck in traffic) so he called Dr. Chen’s office and was able to get the first appointment available that morning.
At my previous doctor, I never actually saw the doctor and usually was assigned a PAC so at least at this office, you know you’ll be seeing Dr. Chen so that’s a positive.

Dr Chen and his staff are engaging and thorough. Dr Chen explains everything in lay persons terms. I always leave feeling heard and well taken care of. He adjusted my painful neck better than the chiropractor I’ve gone to for years, He is always patient and never rushed. I would recommend him to everyone.

Great doctor. Wait was very short. He truly cares about what he does and that comes through in his bedside manor. I am so very happy to have him as my doctor.

Thank Goodness I found Dr Chen. I somehow managed to pull something in my back that made it very painful everytime I inhaled. I called Dr Chen’s office first thing in the morning and they got me right in! Since Dr. Chen is a DO he can also do spinal adjustments (did not know that) so he did some adjusting and I am almost as good as new! Now I have also turned my migraines against Dr Chen, they are proving to be a bit more of a challenge but he is up for it. His staff is always very professional and helpful. I highly reccomend them all.

Dr. Chen and his staff are AMAZING! Being a pharmaceutical rep I have called on and observed many doctors over the last 13 years. This office, hands down, is the best all the way around.
I chose Dr. Chen to be my daughters physician, and my physician, when I was pregnant with her. He has taken amazing care of us in the last 8 years. He is kind, compassionate, thorough, and extremely knowledgable. He goes over every possible thing that is related to your symptoms and discusses with you why or why not he thinks that ailment is the cause. He will do all the necessary tests and give you literature for you to read when you leave.
He is not a doctor who will over medicate you. If you’re looking for someone to just write you a prescription, Dr. Chen is not your doctor. If he’s giving you something it’s because you NEED it. His main priority is your health and safety.
Dr.Chen is so amazing even my extremely hard to impress step father was so impressed with him that he changed doctors after 25 years with another physician.
There is no one else I would trust my child or myself to. There’s a reason he is consistently voted «My favorite Physician» in the Inland Empire magazine. He’s the best!!!

Does not take the time with patients. Rushes through appointment. Does not listen to what patient has to say. Was very disappointed after I left. I thought for sure he would be a good doctor after reading the reviews. But was not happy with my experience. Hope this helps others who are looking for a good primary.

Moved to the IE and thus started the research to find a new PCP. I found Dr Chen online. When I went in the staff was friendly and helpful. First encounter with the Dr was friendly and informative. He doesnt talk to you in Dr language and even shows you back up to why he is making a certain decision. Great find! My family and I will be here for years to come.

I find it unprofessional & unethical to send a bill 6 months after a visit, especially after I specifically asked if I owed anything before I left. It’s a shame profitability comes before customer service.
I didn’t find him personable or helpful either. I got a few vague answers & pamphlets which apparently cost me $ 35 for simply asking. I guess a few seconds of his time is costly. Anyhow, that’ll be my last visit there.

I have to update my review on this Doc! He was on top of his game this time, had all the answers and was very tentative. I’m going to continue having him as my primary!

I really like Dr. Chen. He takes his time and you never feel rushed. What I especially love about him is that he takes the time to inform his patient on their condition. He incorporates you in your treatment and healing process. As opposed to rambling off a whole bunch of medical jargon only a medical Dr. would understand, Dr. Chen actually takes out a book, pamphlet or article and shows you exactly what your condition is, in a way that you can understand. I’ve never had a Dr. Take out a book and EXPLAIN to me what my condition was. I love that he’s young and up to date on things. He’s great!

I’ve been going to Dr Chen for over 3 yrs now and I absolutely love him! These reviews about his mood swings and him being rude are completely outlandish and are prob coming from Disgruntaled ex employees! I go to him for everything from my physical to pap exams etc. he is always very nice and explains everything very thoroughly. Don’t believe any of the negative reviews about him they are completely false! Voted «My Favorite Doctor» In 2006, 2007, 2008, 2009 & 2010 By Best Of Inland Empire, this says a lot about what a great doc he is!

I’ve been going to Dr. Chen for about two years and I really like him and his staff. Everyone is professional and really nice.
I think Doctors always get mixed reviews. Either the staff is rude or doctor is rushed and impersonal. I don’t think that is the case with Dr. Chen. He doesn’t rush thru my appointments. I think he takes the time to really know his patients. I highly recommend him to anyone looking for a family doctor.

My entire family and a big portion of extended family all see Dr. Chen. He and his staff are patient and kind. He is not condescending and actually makes you feel good as a parent and person (even when asking really annoying questions). My husband likes him because he’s mater of fact and not pushy. I like him and his staff because my husband likes him and will actually go the Dr. because of Dr. Chen and because my kids receive top notch care. My kids like him because he talks to them! Really talks to children. We have been to high ranked pediatricians in the area who know kids. In fact, they know kids so well they don’t bother to talk to them. Dr. Chen though, he asks them questions. It’s great. Very great family Dr.

A dangerous and irresponsible doctor.
I went in for a spinal manipulation and one day later I had nerve related stroke. At the hospital they told me that he had injured a nerve while adjusting my neck. I am in the process of suing him for the permanent damage that he caused. I wonder if the doctor even cares how many people he injures for his profits.

My Husband goes to this doctor.
He’s VERY thorough and knowledgeable.
He takes plenty of time with his patients and seems to love what he does.

Dr. Chen who always wears scrubs and not a doctor’s white coat and tie, is very knowledgeable in all the areas he treats. He’s patient, personable, courteous, hard working, accountable. Not rude or arrogant as some other family practice doctors are with bigger offices and several stressed out employees. His office staff is very friendly, professional, nice. He services San Antonio Hospital, Upland.
If you Unilocaler’s are looking for a decent doctor in the I.E. I recommend you read Inland Empire Magazine’s Best Doctors issue (updated each year. See link) and see if any of those doctors are part of your physician provider list (when choosing a doctor).
