Dr Koch immediately was able to see me, and accommodate my pain, as well as provide insight and a prognosis for my tooth. In this day and age, I feel like a lot of doctors are selling you snake oil and false promises just to make a profit. I feel like Dr Koch’s honesty is sincere. You can tell he really cares about his patients and enjoys his profession. The staff was amazing, kind, and made me feel at home. I highly recommend Dr Koch’s practice”


“Dr. Koch was excellent. He thoroughly explained everything and was very considerate of my TMJ issues, asking me if I needed a break throughout the process. He did everything he could to make me comfortable and take care of my TMJ while doing the root canal. “

“I am the world’s biggest chicken when it comes to pain. Dr. Bartling was extremely reassuring. The root canal was completely painless. I didn’t even feel the shots. He is professional, as is the office staff. I highly recommend this office. My husband is equally impressed with his care.”

“Dr. Michael Parsons is the best. Just had my first root canal, and it couldn’t have gone any better. of all the horror stories I have heard, not so with Dr. Parsons. I would recommend him to everyone. Great bedside manner, explained the procedure, and made sure I was relaxed and comfortable. Hagerstown is very fortunate to have such a skilled Endodontist. 5 stars!”
