I had a few concerns and Dr. Lesniak listened to me, addressed them properly, and gave me the follow up I will need.

Dr. Lesniak is a fine doctor. He is clearly interested in the wellness of his patients. One of his best qualities is he listens to what I am saying.

I used the ProHealth care estimate system to understand costs. After reviewing I informed the receptionist I did not want to use my insurance as it is a high deductible and the estimate system showed a significant savings by NOT using insurance. Thus far I have received invoices at nearly 30% higher than the estimate for a check up, lipid and metabolic panel.This gap between estimate and actual is unacceptable. It is misleading.

It was a pre-op appointment. Got blood tests and an EKG, which led to a stress test. Found out some important things about my heart that I would not have known otherwise.

Provider asked me if I want to have another provider referral. I said yes, so provider gave me phone # to call before I called, other provider sent me a a voice mail to contact them.

I am a pharmacist - oops. With a great deal of continuing education in pharmacy with a great deal of pharmacology. I've been Dr. Lesniak's patient since he arrived in Hartland.
