“The was great. However....heads up. When I went to make the appointment with Dr. Ma, Zocdoc showed me what I thought was he availbiility. It led me to..."You are seeing Brian Lorenzon, a nurse practitioner." I wrongly assumed that would lead me to meet Dr. Ma. Wrong. Suspicious that something was off, I called toclarify that I would be seeing Dr. Ma. "No. Your appointment is with the nurse practitioner." Why did trying to make an appointment with Dr. Ma lock me into Brian (no offense to him). I needed a foot surgeon, not a nurse practitioner. We sorted it out on the phone. My call to attention and action: Don't lead the Zoc doc user to an alternative individual, even if he is in her practice. If you offer that alternative, explain why, and provide context to avoid A misunderstanding that costs me a few days to finally book it with the Dr. ”

Dr. Ma was awesome and super efficient!
Verified patient
Dr. Ma was thorough, kind, and competent. She made appropriate referrals for further investigation and communicated how she would follow up once those were complete.
I made the appointment to understand the strange behavior of my feet and legs, but the doctor performed a quick, standardized check and dismissed my concerns without providing any real answers.
Excellent care

Verified patient
Appointment was already booked, had to change
Verified patient
She is the best. I was in the area 2 hours early and she squeezed me in immediately and due to the need for another injection in 7 days, she squeezed me in when no appointment was available for weeks. Pleasant, smart, well worth the 45 minute trip.

Good appointment in timely fashion.
She knows her business and left me feeling comfortable so if things did not get better I would come back. She did not make me feel like what I was feeling was of no concern.
Dr. Ma is just that good.

Office sent a friendly reminder for upcoming appointment with dr. Which is always a good thing for me. Staff and Dr were friendly and answered questions my daughter and I had. TY
Verified patient
She was excellent. The other two firms that I visited before her i.e., orthopedic Associates and Somers orthopedics didn’t come close to providing the service that she provided. She examined the ankle carefully gave alternatives. She gave the good old-fashioned doctor service That’s getting harder and harder to find. ?
