Dr. Sab is OK… however his office/​billing staff is HORRIBLE.
In Dec. 2015 Dr Sab’s office incorrectly charged us for a Medicare visit. No big deal… they said they would reimburse us for the charge right away. Well… after 5 months of messages that were not returned then morphing into VERY RUDE interactions with «Joyce» in that office… and finally having her hang up on the Aetna person who tried to explain the billing process to her, we had to escalate the matter to an arbitrator at Aetna. Of course it was decided in our favor and when I called to check on the status of the reimbursement «Gloria» politely listened and said that our check «was in the mail» but offered no apology for our trouble. Oh well, based on other reviews that have accused this office of «racking up fees» I can only surmise that the return of our $$$ was somehow anathema to these people.

Been seeing Dr Sab 4 yrs! Excellent care & professional service always. Highly recommend 4 Rheumatoid or allergies diagnoses u will get excellent care.

I’ve been a patient for over 15 years. Anytime I have a problem or issue, I can get an appointment quickly and don’t have to wait – I love this about Dr. Sab’s practice. He is also a very good Dr. and has been very helpful with a number of different things I’ve seen him for. Great Dr. and great staff.

I am very happy with the care I am receiving from Dr. Sab and his staff. They have shown great care in diagnosing and in providing medical care. When my health insurance did not cover a medication that would likely be the best for me, Dr. Sab made sure that I received enough samples until my insurance coverage could be resolved. After a weekend when I wasn’t feeling well, his staff was able to get me an immediate appointment. I also received a follow up call from Dr. Stab when he thought his answering service might have missed a call from me. All of these things together indicate that Dr. Sab and his staff are very caring and provide service that is rare in today’s medical community.

I have two disorders of immunity. Chronic Sinusitis (allergy driven) and Psoriatic arthritis. I live in Pleasant Hill so it is not convenient to drive 90 minutes for an appointment; however it is worth it. I’ve searched throughout the Bay Area for a specialist who is certified in both Allergy and Rheumatology and Dr. Sab is the only physician I have found who is «dual certified». He took the time to get a thorough medical history and after just 1 visit and a few tests my sinus issues were 100% better. My (long-​standing) psoriatic arthritis is also getting better with a change in medicines. I’ve previously seen 3 different allergists and 4 different rheumatologists who haven’t done as well.
He’s truly excellent!

Front desk is always a little disorganized and abrupt but Dr. Sab is wonderful… I definitely recommend him!

Dr Sab is wonderful… yes you have to wait about 15 minutes for your apt. but he gives you the time you need and explains everything. I have been very happy with Sr Sab for two years…

Great doctor. Great bedside manners. Knowledgeable and genuine.

i can understand people’s concerns, but i want to write a review about dr. sab and his medical care. he was very patient and explained my recently discovered allergies to me in detail. he gave realistic recommendations on how to manage allergies and was very understanding of my concerns and questions. i was very pleased with his care and would recommend him to others.
i did notice that his office tried to schedule a follow-​up appointment to give me the results to my skin tests, but since i had already come in once for a consultation, and twice for skin tests, i expressed that i would like to get the results as soon as possible. the staff was very accommodating and dr. sab came back in quickly to read the results and go over treatment options. my appointments were always taken on time and i hardly had any wait, even when i arrived early.
overall, i think if you talk with the staff, your tests and treatment can be handled greatly, and dr. sab is very knowledgeable and has good bedside manner.

He seems to be a nice person, but an incompetent primary physician. Stay away unless you need an allergy specialist.

My appointment was at 5 pm. Arrived early at 4:40 pm since I didn’t know if traffic was heavy coming from San Mateo. Checked in and was still waiting at 5:35 pm. No one even acknowledged that they were running late and I was there guessing when I would be seen. This was my very first appointment. I wished I would have walked out of that office since then.
But no, I stayed. Because I really wanted to pin point my food allergies. After weeks of tests, poking, drawing blood and follow-​up appointments (they do the test in their office, but they schedule you to come in the following day so they can collect more money off you and your insurance EVEN THOUGH THEY HAVE THE RESULTS IN FRONT OF THEIR FACE). All my tests came out negative.
For a doctor to tell a patient that nothing is wrong with them and to avoid the foods that flare up the hives and rashes, I mean «Are you kidding me? That’s what I’ve been doing!» His response, «Well, you can eat the foods in the morning and if you have a reaction, come to my office while I am still open.» Who in their right mind eats shellfish at 8 am in the morning?
So listen to all the other reviews here, folks. Don’t go to this doctor, because all you’ll leave with are empty pockets!

I disagree with everyone about Dr. Sab. He has been treating my allergies and bursitis for over four years now and I have never felt better. He listens to your issues and follows through with them. Follow-​up appointments are important, especially if you have been sick. You need to be sure you are over what you have had, which I am all to aware of. All doctors offices are business office. Try to get into Palo Alto Medical Foundation when you are sick. You can get in to see Dr. Sab immediately if you are sick. They will squeeze you in if need be. As far as waiting, in all the years I have seen him I have waited maybe twice more than 30 minutes with an apology once I saw him.
Those who have posted negative reviews will probably note be happy with any doctor!

I don’t want to waste any more time writing a review than this man has already wasted, but to sum it up:
1) He made me make another appointment to spend 5 minutes reading the test results I had a copy of beforehand.
2) He shows no concern over patients’ welfare and wants to stretch out the appointments to make $.
3) He ordered the wrong test for me and I had to point out what I should be tested for.
4) Every time I have a set appointment, he doesn’t end up seeing me until at least 30 minutes later
Save yourself the headache

I disagree with the other reviewers. With a busy office, if only 3 people have complaints then that doesn’t seem to negative. I was referred to him by two physicians. He has been extremely courteous, very professional as has his staff. His office is full so it is unfortunate the ‘happy clients’ aren’t writing on Unilocal.

I went to Dr. Sab for allergies shots for years. This is very much a business office. The doc himself is very nice, but pretty much clueless when it comes to medicine. If you know what you want and just need a prescription, go there.

He was arrogant and insulting. He did not perform the proper physical exam for the diagnosis he gave me (I learned this later when I checked the web). He would not consider all my symptoms, some of which conflicted with his diagnosis. He then told me that the diagnosis was a «throw away» diagnosis, meaning that it was not a real disease process at all. The doctor that referred me to him was appalled at the way Dr. Sab treated me, he doubted the diagnosis, and he will not be referring anyone else to Dr. Sab. Dr. Sab insinuated that I liked having surgery (which had absolutely nothing to do with why I was seeing him). He also insinuated that I was shopping around for a certain diagnosis. He was so wrong. My internist finally diagnosed the problem and it was not serious and it is simple to fix.

I agree with the first reviewer. Do not go to Sab. He is an arrogant doctor who misdiagnosed me and caused irreversible damage. If he is the only rheumatologist to choose from, fill out the paper work to appeal the decision and see someone else. It is possible, just difficult. I cannot believe he can still practice medicine, keyword on practice!

I do not recommend Dr. Sab. I do not question his intelligence or his medical expertise. I do question his ethics and business practices. I think the best example to describe this is when I got an allergy scratch test at his office. He came in to read the results and noted that I tested negative for all the samples. He put on a real concerned face and in a serious tone highly recommended I come in for a follow-​up to discuss the results. I was dubious as to whether he had anything to say, but made the appointment anyway. What did he have to tell me at the follow-​up: «Your test came out negative.» I inquired as to why he requested a follow-​up when we both already knew the test results and pressed further to see if he had anything further to say. He looked at his notes and confirmed that he had no further comments on the test.
This is only one of many examples of this sort of behavior. He gets paid for his appointments and tests regardless of whether they are needed or helpful to the patient. I feel that he abuses this situation, and is thus grossly disrespecting his patients.
