He continues to help advance minimally invasive techniques specifically for colon cancer, rectal cancer, pelvic floor, and fecal bowel elimination disorders.

Dr. Stadler, I may not have told you while I was hosptialized what a wonderful, caring, great bedside-mannered doctor you are, but I am praising you for all your care and thoroughness through all that I went through. Apprehensiveness, scared to death about my surgery, but you made me feel at ease. You never missed a day visiting me for 16 straight days. You never sent a colleague or another associate to check on me; it was always your caring self that came to visit and for that I am so grateful.
