    Dr Lashner was exceptional! He listened to me, validated my concerns, and had a plan to work towards identifying the specific cause of my ongoing issues. He was reassuring that we would find a solution and validated that I was justified in leaving my state (NC) to come to the Clinic. After dealing with these issues for 4 months, I finally felt heard.

    Dr. Lashner listens as I explain new issues/symptoms. He does NOT respond with oh, that's nothing to worry about. He does NOT rush thru the appointment. Dr. Lashner explains and includes me in my treatment. I will continue to recommend Dr. Lashner to Anyone who asks me who I see for my gastro issues & when asked why, my response remains Because I trust him & I trust him because he knows what he's doing.
