Love Dr Len.  He's been my family's doctor for years and always will be.

Overall Rating: 1.0 2022-07-23

He walked in backed up against the door acted like an old handy caped person, made weird sounds. I gave him a look over my glasses. He straightened out his coat and coldly asked why I was there I told him, and he said oh. Listen to my heart and left. It was the first time I have seen him since I started. I don't need a rude non-caring doctor. I need someone who will help, care and talk to me. His write up was a lot different than what I had seen and felt in that exam room.
