I arrived for my appointment and was put into an exam room quickly. Unfortunately, I then sat in the exam room for 1.5 hours waiting on the doctor to come in. Once he arrived, he explained everything thoroughly to me in a manner that I could understand. After, Katrina scheduled my procedure, of which the first available appointment was not until 3 months away.

He is great. He listens to everything you have to say. He asked questions, to know more about your health, and what is going on. He is friendly and is someone I like to have all my medical team, taking care of me. He does not make you feel rushed. Every one I met on his staff is very nice and friendly. Except one. When she checks her blood pressure, temp and ask about your meds. She needs to be reminded of patient courtesy. But the doctor, and everyone else is awesome
