Tommy Chua Sim

Dr. Tommy Sim is nicest man and a very knowledgeable great Doctor. He and his staff are always so nice friendly and helpful.

Very helpful doctor. It's a long wait. But, he's worth it.

If you are sick of allergies this is the place to go. Dr. Sim gave me injections for about 7 years. 15 years later and I am still allergy free.

Dr. Sim was great!! Not only did he get me in almost immediately, but the appointment never felt rushed. He spent quality time, was very knowledgeable, and even called me on his own time the next day to check and see how I was doing. Totally recommend!

I’ve never been treated so badly by an office staff in my life. My girls have been seeing Dr Sim for 5 years. Everything was great (definitely not on top of ANY new treatments or information for food allergies but generally pleasant) until this last week. The day after they posted an open LVN position, I got a very nasty call from a staff member letting me know they would not be following the same procedures as last year for food allergy patients requiring 504s. When I went in to pick up my daughters documents for school, they tried to pretend that they had “thrown them all away” because I had another allergist request medical records for one of my daughters. They finally brought them out to me after I was adamant that I wanted the documents back. They whited out parts of the document and acted like catty, spiteful, petty teenagers. I will no longer recommend this office and will not let any of my children go back. I had to request that they take my daughters pictures off of their FB page because they were never given permission to use her image on social media.

Loved this place on first visit, helpful, friendly and caring staff. On second visit after my wife and 20 month old child walked half a block due to terrible parking situation they ended up waiting over an hour before giving up and leaving. When I called to inquire, the whole attitude changed, no more nice and caring personnel, I guess they don't like being challenged on poor communication and customer service. I told the office manager in follow up phone conversation that I would need my son's medical records as we would find a new doctor and got the "who cares" attitude and the "we're done here" comment. Will share our experience with our pediatrician (his wife) and ask her to find someone better. Loved this place on first visit, helpful, friendly and caring staff.

My daughter sees Dr. Tommy and Dr. Leila Sim. They have the best bed side manner and really care about their patients. It's a great feeling to know that your Dr. will listen to your health concerns. It's even more of a relief knowing that your concerns for your children will be listened to and addressed. The office staff is AMAZING too.♡ My daughter sees Dr. Tommy and Dr. Leila Sim.

Dr. Sims is patient, he listens, he is kind and he doesn’t rush you. I feel very confident I always get the best treatment when I see him. I would not hesitate to recommend him to anyone.

Can't begin to state how pleased I have been w/ Dr. Sim & his entire staff. Referred to Dr. Sim for chronic condition & immediately diagnosed & prescribed new med. that he felt would help. Within only a couple of days of starting new med. symptoms rapidly improved. He even called that evening after receiving 1st dose to check on me! Staff exceptional & pleasure to work w/. Wait never more than a few min. On follow-up with Dr's at M.D.A. they inquired who "new" Dr. was due to significant improvements in my condition. M.D.A. now referring patients! This top-tier, globally ranked research hospital recognizes my cutting-edge treatment from Dr. Sim. Office clean, modern & utilizes current tech. He has great bedside manners which is a commodity. Very personable, friendly & most importantly, knowledgeable & never rush's my appointment. If review sounds over-the-top, it's because accurate diagnosis & treatment is literally life-changing. Dr. & ENTIRE Staff are kind, professional & personable.

Hello I have been under the care of Dr. Sim and his staff for over 14 years. Over this time I have witnessed the best care for not only me but my family as well. Dr. Sim demonstrates his concern for my heath and my family's heath by his time spent with us during visits. Moreover he calls and checks up to see if we are feeling better after a treatment for an illness. Who does that anymore? That is best care for patients. Just a couple of more reasons why we will not go to any other doctor: Dr. Sim reminds us for flew shots each season, recommends the best medication for our pill phobia, the staff is more than willing to help get medication refilled at a pharmacy close to our home or office, even mail order and insurance billing help. I have had a difficult situation with insurance and they have made is easy. To close I volunteer on a farm each year for harvest. This would not be possible without the treatment and loving care of Dr. Sim and his staff. My family and I highly recommend him

Dr. Sim has been my allergist for over a decade. I received excellent care from him and his wonderful staff. I’m moving out of the area and will surely miss them.

I absolutely loved Dr.Sims and the staff! They are extremely helpful and treat their patients like family!

Excellent doctor! Very friendly, he always makes us laugh! My daughter has been a patient for over a year and his staff is ALWAYS really nice. There is usually not a long wait! If you need an allergist this doctor is great!!!

I have a patient for more than 15 years and I have been treated wonderfully.

Usually in and out within the hour. Great staff and Dr. Sim is great too. He cares and he’s funny too.

In almost 20-years of as my allergist, he has proven himself to be both caring and an excellent allergist. His staff are very friendly and caring, too.

Love and miss this office. Very friendly staff, nurses, and Dr. SIM is an amazing physician. One of the best I have had in the years we habe moved around.

As I was making a follow-up appointment with Dr. Sim, I told the front desk receptionist that my appointment with him and his entire staff was "the most pleasant experience I had ever had with a doctor." Everyone in his office was very professional and willing to answer as many questions as I had. Dr. Sim is an excellent physician who takes time to listen to his patients in order to try and help them feel better. I'm so glad I found him. If you want knowledge/expertise, go to Dr. Tommy Sim!

Best doctor ever! He has saved my life, literally , several times before .So caring and highly experienced . Excellent!

I rate Dr. Tommy C. Sim and his staff as excellent or five stars because, during each of my visits, Dr. Sim patiently listened to me as I tried to describe my itchy ailment, and to my amazement, he asked all the right questions, which resulted in a successful treatment. I believe that Dr. Sim genuinely cared for my welfare, and I rate his bedside manner as excellent. I am grateful to Dr. Sim for the healing that he provided, and I highly recommend him to anyone who seeks relief from the annoying and often debilitating effects of allergies. In addition, Dr. Sim's nurse, Crystal, always put me at ease. She is a very caring person. In fact, everyone I met in Dr. Sims office was helpful, courteous, and caring. I rate Dr. Tommy C.

Son had cough for six weeks. Pedi tried antibiotics and inhaler without success. Dr Sim was very interested in my son's symptoms and history. Very kind and caring. Gave us detailed explanation of cough inorder for us to understand. Prescribed the right meds and specific inhaler to son's needs. Saw healing quickly. Great doctor! Not rushed.

I have been a patient of Dr, Sim for over 20 years. He has been a life saver for me. I totally trust him with my life. I can't say that about all doctors.. He is very patient and explains things so that I can understand.
