Dr. Keitz was awesome!

June 01, 2017

Our daughter and I have always felt that Dr. Keitz not only does a thorough physical exam each visit, but takes extra time to get to know the patient and what her/his lifestyle. Our daughter is extremely active, and we feel that is taken into consideration when choosing and maintaining her medication. Thank you Dr. Keitz!

Dr. Kietz is an exceptional doctor. Both times we saw him he is personable, friendly and courteous. He showed us compassion, empathy and unconditional positive regard for what our family is going through, with multiple illnesses with multiple family members. He took the time to listen and understand what illnesses other family members have, even though they are not his patients. i was extremely impressed. I have worked with many doctors in my 46 years and Dr. Kietz stands out the most. :)

Dr. Kietz was exceptional at helping us work through what my child was experiencing. He was knowledgeable, kind, helpful, friendly, and provided us with answers and a treatment plan to help my child get well. While my child was diagnosed with a rare uncureable disease, Dr.Kietz provided us with answers and hope for her future. We feel cared for and hopeful now and that is truly priceless. Dr.Kietz is a gifted and compassionate doctor and we feel lucky to have him in our lives.
