Dr. Karzel is the ultimate physician. He fully explains the surgery process and gives you the time to ask any questions you might have without feeling rushed. My procedure went without any problems and I recovered very fast with little pain. He has follow up emails to keep up with the recovery progress and answers any questions you might have post surgery. I have had several surgeries and would rank him at the top and have no problem recommending him!

Dr. Karzel is an amazing Doctor. I have never felt more comfortable and at ease prior to a surgery ever. He did such a great job on my knee that it's almost as if I didn't have anything done. His demeanor should be an example for all surgeon's. I can't say enough about him and his amazing team.

Dr. Karzel is a rarity of both extremely skilled in his profession and also a very warm and caring personality. If you want a successful surgery and recovery go with Dr Karzel. His office uses an app that does a daily check in after surgery. They answer fast and you have the added security if you do you have an issue you have an answer quickly. He truly is a top Doc

I’ve seen Dr. Karzel many times over the years for knee and shoulder issues. Have had 2 arthroscopic surgeries now. Dr. Karzel is knowledgeable, thorough, friendly and in my opinion tops in his field. His entire team is great.

This is my second surgery (first shoulder, now knee) with Dr. Karzel and both have gone extremely well. He understands how important it is to get back to the sports activities that I was doing before surgery. He has a calm, caring manner and is genuinely concerned for his patient’s well being. I would highly recommend Dr. Karzel.

Having fairly extensive shoulder surgery only four weeks ago, I can say that I am feeling amazing. Dr. Karzel did outstanding work on an old injury and my new injury. Because of the great work that the doctor has done, I need to constantly remind myself to remain compliant and let the healing continue. I can't wait to begin PT and get back to all my favorite sports. I am blessed to have been referred to Dr. Karzel, Dr. Peffer and their great nursing staff.
