Dr. Kwasniewski is friendly, knowledgeable and efficient. He takes time to answer all of my questions (and I have a lot!) without making me feel rushed. He explains things so that I understood my diagnosis. Also, appointments are easily booked online which is a huge bonus in my opinion.

Steve was amazing and very thorough and really wanted to get to the bottom of my mobility challenges. He suggested a Cortizone shot in the knee and it has been life-changing. I look forward to my next appointment with Steve in a week as a follow up. Very thorough very professional.
June 30, 2025Susan B S.Verified patient
Dr. Stephen Kwasniewski was absolutely amazing. I’m terrified of doctors and when we met, it felt like we were already friends. I’m 32 years old and he made me feel at ease. The office staff? Also amazing! It really was a pleasant experience.

Great experience with Zocdoc
For sone reason there is always a long wait to get to see the Dr. I had an 11AM appointment that they asked me to arrive by 10:45 Am. I was taken in for X-rays and then sent to a waiting area until the Dr came to see me approximately 33 minutes later. I was very anxious to see the Dr and get some updates so my anxiety levels were high by the time the Dr arrived. I think this office should do a better job of scheduling appointments so that patients aren’t left waiting over 30 minutes in an empty room thinking they were forgotten about
In any case once Dr Stephen K came in to greet me and explained everything to me I was relieved but I never expected to have such a long appointment
March 18, 2025Sharon F.Verified patient
Love my provider, takes the time to explain what the treatment plan options are and recommends what is best based on my history and presentation.
