“Dr. Kavaler and his entire staff were absolutely amazing!! Very supportive, and caring and went above and beyond for me! I will never forget that especially when I was sick for 1 month! Thank you immensely everyone!”
“Dr. Freuman is an exceptional doctor who made a real difference in my recovery. From the start, she listened carefully and quickly identified several approaches to address my symptoms. What stood out was how clearly she walked me through each option and explained the reasoning behind them — it was both reassuring and genuinely helpful. I left the appointment feeling confident, and that clarity ultimately helped me recover. Highly recommend.”
“Dr. Desai was outstanding in what was a particularly stressful situation for me. He was attentive and thorough from start to finish — listening carefully, walking me through his conclusions, and explaining his thinking every step of the way. His bedside manner is truly exceptional, and the procedure itself was a seamless, comfortable experience. I couldn't have asked for better care. Highly recommend.”
“Very professional!!!”
“Just a great doctor”
“I had an excellent experience at this clinic yesterday. From the front desk to the nurses, anesthesiologist, doctor, and support staff—everyone was incredibly kind, professional, and thorough. My doctor, Dr. Wong, was especially wonderful—very attentive, reassuring, and clear in all explanations.Every step of the process was clearly explained, including insurance details, copays, and the procedure itself, which made me feel completely at ease. What stood out most was the exceptional bedside manner across the entire team—something that’s unfortunately not very common these days. I felt genuinely cared for and never rushed. Highly recommend this place!!”
“Dr. Wong is very nice and very professional.I had a very brief but pleasant medical experience with Dr.Wong.”
“Dr Tuyama took her time talking to me about any issues and is a good listener. Highly recommend.”
“Great gastroenterologist with a warm bedside manner. Highly recommended.”
“Excellent facility!!! Dr. Yang and the staff are all professional and caring individuals!!! Everything went smoothly.”
“Super thorough, efficient, friendly and caring. A++”
“Super personable, both the doctor and the entire staff. I see the doctor once every 5 years for 5 minutes and he makes you feel important to him; the staff tries very hard to make the process smooth.My only complaint is that i would have liked to have slept another hour or so before being woken up. I would pay extra for that :)”
“From my very first consultation with Dr. Metz, it was clear I was in the hands of someone who truly listens. I came in with a complex medical history and a number of concerns, and rather than rushing through the appointment, she took her time to understand the full picture — asking thoughtful questions, reviewing my background carefully, and making sure nothing fell through the cracks.What genuinely impressed me was that Dr. Metz went well beyond what I expected from a gastroenterology visit. She ordered a comprehensive allergy panel that ended up being one of the most valuable pieces of information I've received in years of medical care. The results uncovered several significant food sensitivities and confirmed allergies that I had not previously identified, and Dr. Metz walked me through each finding with clarity and patience. That level of thoroughness changed the way I approach my diet and overall health — and I'm grateful for it.Her attention to detail is outstanding. She clearly reviews your chart before walking into the room, and her follow-through between appointments reflects a physician who is genuinely invested in her patients' outcomes rather than simply moving through a caseload.Equally important to me was how comfortable she made me feel. Medical procedures can be anxiety-provoking, and Dr. Metz has a calm, warm, and reassuring presence that put me at ease from start to finish. During the procedure itself, I felt informed, respected, and completely confident that I was in capable hands. Her demeanor never felt clinical or dismissive — she treated me like a person, not a chart number. I would highly recommend her to anyone searching for a Gastroenterologist.I am most grateful....”
“Dr Desai the best gastro doctor I’ve been to and I’ve been to a few. Cares about his patients takes the time to get to the route of the issue. Hes the best”
