had an excellent experience with Physician Assistant Ayelet Mottahedeh during my recent gastroenterology consultation. She was professional, knowledgeable, detailed oriented and compassionate. I appreciated her prompt follow-up after my bloodwork results and the clear guidance she provided. Her care and professionalism exceeded my expectations, and I highly recommend her.

Dr Amy Tan is amazing, she is professional and makes you feel very heard. She saved my life when she d diagnosed my ovarian cancer. Thanks to her I have a chance! Im presently undergoing chemotherapy. I had no symptoms and without her I would have known. She is just an amazing lady who really cares about her clients.

My experience was amazing. Beautiful building, friendly staff. What else can you ask for. I was early for my appt and they were very nice to see me before my time and I did not have to wait long to be seen. I would recommend this facility to anyone. Thank you for making me feel like I matter. It is rare you encounter professional hi will treat you with humility and kindness. Thank you!
