James Tidwell, MD

“I went into dermatology because it is the perfect mixture of people, science, and meaning. Being able to tell someone that I cured their skin cancer is a dream come true.”

Why He Chose The Medical Field
I used to work as an engineer and switched over to medicine. I love meeting new people, solving their problems, and seeing that relationship build over the years. I’m motivated to use the newest technologies to fight and cure cancer.
