Good !

01/08/2024

It Was Awesome

01/08/2024

I think Dr. Leshen could spend more time with his patients. I transferred care to him with cautious optimism after reading some patient reviews about him seeming "rushed" during office visits. Unfortunately, I found the same to be true. Gratefully, my needs were such that I didn't require him to spend a lot of time explaining things. However, patient perception is his reality, so taking a few extra minutes to narrate care could serve him well.

01/03/2024

I will not be back and will urge others to do the same

12/29/2023

Very good

12/21/2023

Very good

Good care...

12/13/2023

I like Dr. Leshen. He listens to what I have to say.

12/12/2023

Dr.Leshen is an excellent listener and knows his stuff.

12/11/2023

All went well, though I had to wait in the room for the doctor to come in for the visit

12/07/2023

I got less than what I was expecting. I got the radiologist’s report without the expertise of the specialist I employed for his expert opinion. I was short changed!

12/06/2023

Lack of respect as to what a person's time is value wise. We all have things to do and waiting for a physician seems to show total lack of respect for our time.

12/01/2023

ALL GOOD

11/30/2023

Happy with care. Would recommend

11/29/2023

This was a quick visit. Dr was running late. I know from experience that he is there for me when longer visits and conversation is needed.

11/29/2023

I had a helpful and pleasant experience

11/28/2023

I appreciate that Dr. Leshen went to great lengths to make sure all the testing that I needed was accomplished. He is most committed as a physician.

11/26/2023

You can feel Dr. Leshen cares, is knowledgeable, and kind. All I could ask for.

11/13/2023

I only wish I had a bit more details on my EKG results, but they were wonderful outside of that.

11/11/2023

Very good entire time.

10/27/2023

He doesn't "order me" to do things I don't want to do.
