I had my first colon screening last Friday, 6-28-19 with Dr. Snowberger at Old Town Endoscopy. Not knowing what expect, I must say the prep was not pleasant, but it's not supposed to be - all things considered. Dr. Snowberger and her staff were not only nice; they were KIND. There is a difference. Her lady at the office called me the day before and walked me through some concerns I had. Once at the facility, no one rushed me, each person explained their role and what I was going to go through with them during my visit. Dr. Snowberger came highly recommended by my Gyno Nurse, Melissa Lang and I'm so glad I took her advice. The pace was steady and over with faster than I thought it would be. I kept expecting discomfort after I left but it never happened. It all went so smooth. I was nauseous when I arrived but it went away once things got started and it never came back. It's still a bit of a mystery to me how well it went and how great I felt (and feel now) since it was done. VERY grateful my screening results were best case scenario and that I don't have to go through that yucky prep for another 10 years, but I know I will return to Dr. Snowberger and Old Town Endoscopy! Thank you Dr. Noel for such a great experience! Lisa (Sally) Johnston

Dr. Baker is absolutely amazing!! He knows how to look at the patient and not just numbers.. he was able to help get our daughter off of the NG tube in 2 weeks when others had recommended placing a G-tube. We are so thankful to have found out about him and are forever grateful! I would absolutely more than recommend him to anyone, especially those with feeding issues. He’s very experienced!! Thank you for everything!
