John Lesniak, MD

I have generally received great care except on one occasion. That lack of knowledge is now costing me thousands of dollars a year. I will not recommend the endocrinology department at the Hartland clinic because of this. I now happily go to the Oconomowoc office and receive great care.

Dr. Lesniak caught something on my medical history that needed a follow up after two years. I really appreciated that because I completely forgot about it

I have been seeing my provider for over 25 years. He is very good & trusting.

Dr. Lesniak is very kind. He is easy to talk with.

My family is very pleased with Dr.Lesniak. He is a great Doctor

Good talk with Dr, reviewed health concerns

Alway polite and attentive greeters and nurses. Dr. Lesniak is exceptional in listening and providing feedback.

Look forward to going to the doctor. All good experiences

Dr. John Lesniak is very caring, professional, good listener, and gives me good instructions. He is a great doctor and I am very lucky to have him as my care provider.

It was good.

Dr. John, as always, listened to any concerns I had. I appreciate his gentle nature, his listening ear, his vast medical knowledge. I am very thankful for him.

Wellness visit.

Dr.Lesniak was very thorough, reviewed my medical history and prescription meds and answered my questions in a satisfactory manner.

Dr. Lesniak was very up front and informational as I am switching Doctors within the ProHealth system. Excellent personality and informative.

I fell and to have stitches. I had to have them taken out so Dr Lesniak took them out himself and it is healing very well.
