Wow! I saw the one review and I've never heard one negative about Dr. Hesslegesser , not once. I think he is the best! He has the most years experience, explains so you understand, truly cares, and is so smart, and incredible memory. I was told by 3 Dr.s it was too late. I was allergic to my Chemo, couldn't have surgery, he is the only one who diagnosed my Steven Johnsons Disease, I'm so grateful for radiation & Dr. Hesslegesser because he doesnt just go by the text book Im still here!!
