My 1st time meeting Dr Linn and I immediately felt comfortable discussing my issue. He explained the procedure that I would need thoroughly, showed me my CT scan and pointed out what needed to be done. I am confident he will take good care of me.

This was a first contact appointment. I appreciate the patience Dr. Linn and the entire practice staff showed during my visit. My questions were answered. A surgical plan was agreed upon. Directions on how to prepare for the surgery and what was expected of me and what I can expect of the surgical team were provided. Connections between my primary care physician and Dr. Linn were taken care of as expected. Thank you.

This was a 10 out 10 experience with the TEAM at Dr. Linn's office. Hands down the best all around experience I've had with NS/Endeavor. Leadership needs to find out exactly what they do, bottle it, and give it to every other team at NS/Endeavor.

Dr. Linn was recommended to me by one of my other physicians for which I am so extremely grateful. Dr. Linn is genuinely one of the nicest guys, very professional and extremely knowledgeable. His calm demeanor is so reassuring leaving you with the feeling that while in his care, you have very little to worry about. In fact, my wife, who was with me during my procedure and had not previously met Dr. Linn, felt so comfortable with him as well as the entire staff at Highland Park Hospital, she continues to recommend both Dr. Linn and Highland Park Hospital to everyone she gets the chance to. According to her, "he is the man to see and that's the place to go!" Suffice it to say, I can't say enough about Dr. Linn, he is one of the very best!!

In the office, I experienced Dr Linn as calm, solid, present, caring and kind. As my surgeon, during the operation he encountered unexpected, potentially life threatening conditions. He calmly pivoted, solved the problems and, in my view, without much fanfare, saved my life.
