Dr Treyzon was thorough, patient, and exceptionally caring in his approach to my presenting issues. I felt for the first time that here is a gastroenterologist that has listened to my concerns, and has a well defined plan to reach the diagnosis and finally get the treatment after years of having GI concerns. A great start to finding answers!
