I've read all of the negative reviews for this practice and just wanted to add my 2 cents worth in since opinions are like body parts, everyone has them. I was diagnosed with CLL cancer in 2010 and my Oncologist suggested that since some cancers as far as how it relates to the body sort of bring on other cancers, I should seek out a Dermatologist and have a full body scan annually. There was a large practice, which I will not name, that was located in Memorial North Park Medical Center and I started seeing a couple of their of their Nurse Practitioners. I went each year since and each time was pronounced for the most part clean with no Carcinomas for about four years. Since I had been passed to a female N.P. for the past couple of years I felt a little uncomfortable with her doing the full body scan, I guess I'm sort of a prude in that department so I was seeking out another practice where I could actually see a real live doctor instead of a N.P.. That is when I found the perfect fit for me with Dr. Mark Tusa at the Chattanooga Skin & Cancer Clinic, he hasn't been onboard with C.S.C.C. but for a couple of years and I was so lucky that I was able to get him to accept me as a new patient. Well to say the least he has helped extend my life by years - the first time I walked in and he did his scan he requested 4 biopsies from his nurse and of the four three turned out to be Squamose Cell Carcinomas (pretty serious) and it was apparent to me that these didn't develop just in the past year since my last scan at the other Dermatologist practice. Since those first three just 3 months ago he has also removed several more. He attended and graduated with honors from Chicago College Of Medicine And Surgery in 2004, and I promise he's unlike any other doctor you will ever meet - with his concern for his patients he goes out of his way to call you day, night or weekends to personally give you the results of your biopsies as well as tell you that if you need to talk with him after hours about a problem that may possibly develop from the surgery just call his answering service and he will respond (although with his and his surgical nurses detail to attention I've never had any issues from any of his surgeries). I'm reluctant to spread the word on how good he is since at some point I can see him being overwhelmed with requests from new patients but he deserves the praise and he is a great asset for Chattanooga Skin & Cancer Clinic and will be for years to come!!!
