I recently had a procedure done with Dr. Carly Barth which I was completely nervous about. Dr. Carly Barth was amazing along with the staff. Thank you for putting me at ease!

I don’t know why every doctors office in the world isn’t ran like this place, it’s so incredible to have such a care free process. I’ve been to many doctors this last year and DR Barth has been wonderful and validating, something many doctors have not been for me.

Nobody walks into the doctor's office looking forward to a colonoscopy. I was nervous because a friend of the family was sick. From the moment I stepped out of my cau there was a gentleman who made it seem I was the most important client of the day. The staff was excellent and the facility was clean. Dr. Marshak spoke with me like I was a person. I had both an endiscopy and a colooscopy and it went well (as one could hope a procedure such as that would og). I recommend this office to anyone.
