Dr Lesniak is an incredible physician. He listens to your concerns and is extremely kind and patient. All physicians should be so dedicated like he is. Thank you for taking such great care of your parents.

My only complaint is there was an excessively long way to secure an appointment with Dr. Lesniak as a new patient. I made the appointment in December and the earliest available date was at the end of June. For someone who was new to the area and needed ongoing care that was concerning as I was on the verge of running out of medication’s before I would have been able to see the new doctor.

Dr. Lesniak listens, amplifies what he understood, and/or sought further query, then provided insightful and learned feed-back as well as recommendations and suggestions.

Dr. Lesniak explained things very well to me, listened to me, and suggested a new medicine that no doctor had ever suggested to me. I’m very grateful that I decided to try a new doctor, he seems great!

Hackensack has everything in the same place: my physician, thyroid doctor, vaccines, blood work, specialized tests, and a walk-in clinic. I do not stress because it is a team.

Always have a positive experience.

Dr. Lesniak listened to my concerns and then walked me through his diagnosis over a one-hour period, which was incredible. I come from a perspective where most medical folks spend 2.5 minutes talking to me and then move on to the next person so they can file their insurance claim and ramp up revenue. Being able to talk to the doctor for that period of time was incredible and made me feel valued.

Have been seeing Dr. Lesniak for while. He is always thorough with his reviews of my lab work. He listens to my responses and explains everything to me. He makes sure that any prescriptions are current and update if needed. He is very professional and takes the time. I am happy he is my doctor...

Positive , professional and pleasant experience from check in to check out. Dr Lesniak is a charm. He took the time to listen attentively to all of my concerns and addressed them all in a professional and caring manner. He truly made me feel comfortable and at ease during my office visit. The intake tech Navi was terrific too gathering my outside health records for Dr's review prior to my exam. Thanks again to the HMHC team for making my first visit exceptional!

I love how you have the one stop shopping at this facility and am hoping to find doctors there for a few of my other health needs. On the down side. Finding a parking spot was a mess but it was the week of thanksgiving so I'm willing to let it slide ?
