ELIDA P.
Patient
If you are looking for a compassionate, knowledgeable, efficient, responsive, caring, flexible, office that treats you as an individual human being and not just another number, look no further! What I love about Dr Mehta is that he is an extremely compassionate, and knowledgeable doctor. With him, you feel more like you are visiting a caring friend and he knows you by name. He is knowledgeable not just in traditional medicine, but also always willing to offer and try alternative more natural modalities!
RENE M.
Patient
I can’t say enough about Dr. Mehta. He took the time to research and figure out why my ALP was low. Come to find out I have a rare bone disorder and now have the information I need to get help. I’ve never met a doctor who I feel truly cares about his patients and wants to help them feel their best self until I started seeing him. If you’re considering a doctor, I highly recommend Dr. Mehta.
CHRIS C.
Patient
The staff doctor billing are top-notch. Beginning with staff, they are very responsive to request and or needs. The doctors, take all time necessary to evaluate and listen to the patient. And from billing, they are on point with getting necessary, paperwork, submitted, and file for insurance processing. Those are three huge pluses in my book that weren’t anyone searching for a primary care physician to consider this practice without any hesitation!
CINDY C.
Patient
My partner in healthcare! Both Dr Mehta and his office team are there for me. In the two years that I have been with this practice I have been able to wean off of an arthritis medication that I have taken for 20 years. He has guided me through the MRT test which is a blood test that measures the bodies reaction to foods and chemicals to identify food sensitivities. Those changes I’ve made in my diet to exclude the two “red” foods has facilitated me to start a weight loss journey that has me down > 50lbs! Yay me! If you’re looking for a PCP that will listen to you, and guide you with his knowledge this is where you need to be!
SHANIE Y.
Patient
Dr. Mehta is extremely knowledgeable, kind, compassionate, friendly, thorough but yet so humble. He is proactive, he takes his time with every patient and explains things effortlessly. His vast knowledge and putting things together is extremely impressive while still treating you like a person and not a number. Saranda is the PA and is also exemplary! You will never find a better level of care and compassion than you will with Dr. Mehta and his staff. Whether it's making an appointment over the phone or getting labs drawn, every single person in the office are just incredibly helpful and friendly and make you feel like family.
YASIR Z.
Patient
I took my father to go see Dr Mehta for his follow up appointment. After meeting him, I know that my Dad is in great care under Dr Mehta and his friendly staff. He is very personable person he took the time to examine my Dad and answer all his his questions in detail without rushing him. Dr Mehta is very knowledgeable professional and a passionate doctor who genuinely care for his patient’s health. It’s really good to see a doctor these days who can treat you like human rather than just a number for their practice.
