October 11, 2024Emilio E.Verified patient
I booked both an appointment for myself and my daughter. We were taken immediately at our appointment time We were given a considerable amount of time which is not typical In this current medical healthcare system Where you’re lucky if you get 15 minutes before your scooted out the door. He listened asked questions was very thorough. Great personality seems very well-versed and educated and was the breath of fresh air I was looking for In today’s healthcare

I am not a fan of health providers in the United States and tend to travel overseas for my health needs. My US health insurances requires a PCP and through ZocDoc I saw John's profile and plethora of reviews compared to others on ZocDoc. I took a chance off the reviews and booked an appointment. I received a call from John before my appointment to confirm I'd like to see him as I am not local to where his practice is located. Through my new patient interview with John through telehealth, I immediately felt the quality of how health and patients are viewed when I get care overseas. John is a brilliant individual and while at the time of this interview I have yet to go to his practice in person, I say whole heartedly he is one of the few healthcare providers I have met in the US who respects the views and health of his patients and abides by his Hippocratic Oath.
