Very good overall experience.
March 10, 2022
I find the provider friendly, professional and efficient, however, they seem over worked. Also, I wish that the Medical and Insurance industries would be more open to more wholistic review and recommendations for other natural options besides just drug prescriptions. We need to be considering and discussing all options and focus more on preventative options and tests. Providers need more help and more time to allow more time between the patients and Doctors. Time between Medical Appointments seem way to tight together.

Dr. Lesniak is always thorough and pleasant. He has always taken good care of me. This was my annual wellness check and it covered everything.

I'm extremely happy with the care I receive from Dr Lesniak, his assistant and all the staff at Hartland Clinic. No complaints at all.

I was a little disappointed that they didn't have anyone at the time of my appointment to do labs, so I had to make a follow up appointment.

I feel Dr. Lesniak is personable and very thorough. He always goes through all aspects of my medical history and patiently answers any questions that I may have.

This appt. was scheduled as an initial consultation/physician. Two days before the appt. I got very sick and was questioning if maybe I had the flu or COVID. The appt. became a test appt. for the flu and COVID. Fortunately all results were negative.
