My PA Scott did a fantastic job of going over my records with me, making the transition to a new doctor and PA so much more comfortable. Change can be difficult when you've been seeing the same doctor for years and have developed a solid relationship with your doctor and his/her assistants. I have also spent time with Amanda, who is so personable and understanding. Dr LeeAllan is also very thorough and thoughtful, and she takes the time to listen and weigh out a 'course of treatment'. I'm feeling way better about Dr. Walling's retirement!
Response from the owner:We are so glad you had a great experience, thank you for trusting our care team.

I met with Dr Scott Zeilstra. He was very kind, gave me his full attention and gave thorough advice and explanations. I felt very confident we will get to the core of my GI issues.
