Been battling UC for over 30 years. I only wish I’d have visited Dr. Sideritis sooner. He is well versed and caring. And he is up on the latest developments in the disease. Does not over-doctor and offers different alternatives.Colonoscopy went as smooth as could be and received results promptly. Strongly recommend.

Everyone was very professional and helpful. The PA I met with listened to me and answered all my questions. I was able to book the procedure much earlier than I would have in MA where I live. I plan to use this practice in the future if it becomes necessary.

Very friendly and professional staff. Dr. Kadam is one of the best doctors I've seen in my lifetime. I would highly recommend him. He is very attentive to your personal concerns and is very caring.

My experience here was nothing but amazing. I was so nervous but nurse Gracie made me feel so much better. Thank you Gracie for your hospitality, professionalism, and patient care. She even followed up with me the next day to make sure I was okay. Definitely recommend this place. Gracie you’re the best!!! We need more nurses like you. Thank you.

I love Dr. Sideridis! He’s been an amazing doctor over the years, spends time with his patients, and is very thorough. However, the new office policy is that you see the PA for everything, and the dr’s will just do the procedures. I’ve been coming to the practice bc of Dr. Sideridis! The PA seemed knowledgeable and nice enough. I can understand utilizing a PA - but for every visit for now on???
