DANIEL R. CONLIN, MD REVIEWS

I was very impressed by Dr. Conlin and his staff. Dr. Conlin is highly skilled, professional and has a lovely manner with his patients. The procedure was handled with sensitivity and a bit of humor, which I very much appreciated. The office staff was terrific and helpful every time I phoned. I would recommend Dr. Conlin to anyone needing a Gastroenterologist in the San Francisco area. He is a great doctor--you will be in very good hands.

Super kind, efficient, and approachable doctor. Both the staff at the clinic and for my procedure were kind, caring people. I wouldn't go anywhere else. Thank you, Dr. Conlin and team!.

Wonderful staff and Dr. Conlin is very professional and a great communicator.

FRANK J. FARRELL, MD REVIEWS

I went to Dr. Farrell after seeing many drs who misdiagnosed my severe stomach issues and dramatic weight loss. Dr. Farrell immediately scheduled his own tests. He was always kind and patient and explained his findings to me at each visit. He prescribed meds that immediately eased my discomfort. Dr Farrell is knowledgeable and aware of new medical updates. Due to his diligence and perseverance he identified exactly what the cause was. My symptoms improved immediately and he advised me how to wean off all the meds i had been taken. We were both so happy when the final endoscopy shown there was no more Inflammation. This is long over due review I am forever grateful to Dr. Farrell He is the best!!!.

Dr. Farrell explained the procedure very clearly and performed the procedure very efficiently as explained. He is highly skilled, very patient and very professional. He also explained how I possibly felt after the procedure and advised me all the steps to take to return to normal life. By knowing what is expected has helped me tremendously to cope with the recovery process. I trust him for all my medical needs.

Dr Farrell has provided my routine colonoscopy procedures for the past 25 years. Additionally, he performed several other endoscopic procedures for me during several acute illnesses while hospitalized. He is friendly, very compassionate and a clear, concise communicator. I have complete confidence in him.

CATHLEEN N. CABANSAG, MD REVIEWS

Dr. Cabansag is the best and so is her whole office personnel. She is very professional, attentive, caring, and reassuring. I trust her completely with my upper GI issues I would highly recommend Dr.Cabansag to any one who is looking for a dedicated professional doctor to care for his/her upper Gi needs. I had a wonderful and gratifying experience with Dr. Cabansag and her staff. You will not regret becoming a patient of hers. Sincerely yours, Esther Lue.

Dr. Cabansag is great. She's very caring and thoughtful. I was diagnosed with rectal cancer in 2003. The doctor I had been seeing never followed up after a colonoscopy even when the prep was incomplete and another colonoscopy was needed. Dr. Cabansag gave me more tools in my toolbox to combat the chronic effects of the cancer treatment. She also ensured my colonoscopy was completed because she knew how distraught I was regarding prep. I also received a followup call and appointment. I highly recommend Dr. Cabansag.

Dr Cabansag is amazing. It took me about 3 years to find her. Since being in her care she identified my condition. She started me on meds that lessened my symptoms. I've tried to keep her as my gi dr through multiple insurance changes and so far I've been lucky. If you have IBS or IBD symptoms I highly recommend her.
