I would go back and will recommend him to friends. This was my son’s second appointment with Dr Greene in four weeks. Dr Greene is excellent.
June 30, 2025Nathaniel S.Verified patient
The front desk was helpful and receptive. The sign in process was quick and efficient. The PA was also helpful and efficient before we met the doctor. Dr Greene was effective and thoughtful while talking to my son and diagnosing the issue and resolutions. Excellent and quick visit.

This was my first visit with Dr. Gleason, and it went extremely well. She was thorough, professional, listened, offered detailed, easily understandable explanations, and alternatives for treatment. I would highly recommend her and would definitely return should I hve a future need.

Dr Gleason is incredibly diligent in her evaluation. She was professional, relatable and explained very granularly the circumstances and images. I really appreciate her candor and communication. I would look no further than her if I needed a doctor in this space!

My appointment was on time, x-rays were taken and I was seen, evaluated, diagnosed and given a treatment plan by Dr. Gleason in about an hour. She is personable, professional, knowledgeable and straightforward about options and outcomes. I was extremely satisfied with my experience and look forward to being treated by this professional and courteous staff.

I have had a very sore / strained MCL for several months. Icing and PT wasnt able to get me moving like I needed. A friend recommended I see Dr. Levchenko, as he had resolved a similar issue with their knee.
18 hrs after seeing Dr Levchecnko, my knee feels so much better and has not bothered me at all today. Fingers crossed that PT works for me this time, but this is a very good start right after seeing Dr Levchecnko.

This is my second opinion for my back. What I appreciated about the doctor was his honesty. He explained that he usually doesn’t see patients with this kind of back pain right away, but since I was there, he was willing to take the time to speak with me. We did X-rays, and overall, he made me feel truly heard. I would recommend him because he took the time to listen, explained everything carefully, and reviewed the X-rays with me closely.

I had an appointment to have my hand checked after a prior injury, and the experience was excellent. The doctor took the time to really listen to my concerns and explained everything clearly in a way that was easy to understand. He had a great bedside manner and made me feel comfortable throughout the visit.
The office itself was very clean, and the staff were friendly, professional, and efficient from start to finish. Overall, it was a very positive experience, and I would definitely recommend this doctor to others.

November 21, 2025Karina G.Verified patient
I hurt my hand a week ago. By the time I was able to see Dr Cantlon, most of the swelling had gone down and pain had lessened greatly, but the office still did an X-ray to be certain there was no hidden damage. Dr Cantlon told me to continue icing and that I should make sure to exercise my hand so that it doesn’t stiffen up. He also said, it would be okay to use hand weights as long as I was comfortable holding them. This totally put my mind at ease and I’m really glad I now can resume chair yoga and strong & fit classes. I got to the office 15 minutes early and was seen immediately. Also, everyone listened to me and made an effort to speak clearly and loud enough that I could hear them. I especially appreciate that.

I felt welcomed and I appreciated being taken in almost immediately. Hailey and dr. Mark were wonderful. Such a calm presence and very attentive. I admire what a good listener dr. Mark is. My case is a head scratcher but he was very help providing options about next steps. I will definitely be coming back if/when the pain returns.

The staff was so friendly and warm, they were on top of everything prior to me going in. Ethan, an NP I believe went through all my details thoroughly with care and caution. Dr. Otten was really great. He was easy to talk to, cared about my concerns, reassured me I was ok and provided a recommendation for follow up with a different doctor. Overall, I felt heard and was given the best bedside manner- not rushed or undermined. .So grateful to have met this team. .
