“Dr. Hager answered all my questions, and I never felt rushed during my appointments. I felt like he was talking to me the way he would if I were his daughter getting treatment.”

How Dr. Hager helped Stacy beat Hodgkin’s lymphoma


“My husband has been seeing Dr. Hager since 2009. He has a condition that will require him to see this doctor for probably the rest of his life. We have always been very happy with the care he gets at cCARE. Dr. Hager is kind, compassionate, explains things thoroughly, and has a great sense of humor. When my husband’s illness required a referral for an out of town specialist he did not hesitate to do so immediately. That is a very good sign that you have a good doc who is looking out for the patient and not his ego!! We’ve dealt with too many of those! Dr. Hager and his staff have always been there for my husband and all of his needs and we have felt very well cared for.”
