it was a great experience.

I truly can't say enough good things about Dr. Zahka. I was impressed by several things: 1. He was prepared before he entered the exam room--knew my daughter's history despite not having seen her before, and previous cardiac care was provided in our former state of residence. 2. He spoke to my daughter as well as to me. She's only 4, but it is her health and she deserves to be spoken to. 3. He didn't rush AT ALL. Certainly this wasn't the case, but it felt as though we were his only patient of the day. I have already recommended Dr. Zahka to others and will again.

Dr. Zahka was one of the most thoughtful and understanding doctors we've ever met. He took 2 hours to thoroughly go over our son's medical history, understand our concerns, and explain the situation and possible follow-up. He also spent time to walk us through relevant questions in writing, which was helpful as we referenced them after the visit when relaying information to our family. Dr. Zahka cares about his patients at all levels, not just physical care.

The care provider acted a bit "put-off" by my appointment for my child. I was seeing him as a specialist for potential Marfan's Syndrome diagnosis, recommended by my pediatrician, after my child's annual physical exam. The provider was a bit arrogant in his approach with me, as if I was "over-reacting" with the visit. Ultimately, my son was not diagnosed with marfan's, and the outward characteristics that the pediatrician found, this provider confirmed inconclusive.
