I sincerely question the ethics and integrity of this practice. After speaking with my elderly mother, she were “discharged”/released as a patient when attempting to cancel and reschedule an appt. Unavailable front office and overall extremely unprofessional. I would give this no stars if possible. This doctor and practice forgot the meaning of why they got into healthcare.

Do NOT go to this drs office. My sister had a very serious condition that was highly contagious called C Diff. It took them almost 2 weeks to call her. Luckily she went to another GI dr for a second option, and he took this very seriously and told her what to do and got her the medications she needed. It’s amazing that the other GI dr interceded otherwise not only would my sister have become worse with this deadly disease, she could have infected others. Shame on them for their lack of responsibility!! PLEASE do NOT go there. Don’t risk your life like they did with my sister !

Dr. Yap is such a wonderful doctor. Very informative. Understood the urgency of needing an appointment for my son. Promptly booked an endoscopy and was very thorough of what to expect. Personally called with the results of the biopsy. Continued to answer all my questions. I highly recommend Dr. Yap! Patty-Irvine

Even before we signed up with him, he called us several times and our PCP to help to get special authorization to see him. He understood our urgent need and was very careful to call to follow up. Never had a doctor so careful and attentive. At the exam, he was thorough on my husband's history and even called the drug company immediately to see if any interactions between the malaria pills he will be taking and his hepatitis medicine. Also had his administrator call for an overdue liver ultrasound right away. Overall, we could not have found a more compassionate and careful doctor, respectful and mindful of patient's needs. We are thoroughly impressed and grateful to have such a doctor to care for our family.

Dr. Yap is an excellent doctor. He is very caring, kind and professional. My Mother found the early stage of stomach cancer in the year of 2012. She could have been in a much worse sitiuation if it hadn't been for his help. Thanks to Dr. yap for the early detection and follow up.
