Additionally, he completed his Colorectal Surgical Fellowship at the University of Ohio before returning to Phoenix to join Pinnacle Colon and Rectal Surgeons. 

With a passion for utilizing technology effectively to minimize the patients’ pain and improve the speed of recovery, Dr. Weiss specializes in laparoendoscopic (minimally invasive) treatment of colon and rectal disorders, inflammatory bowel disease, colorectal malignancies and benign anorectal diseases. He is skilled in robotic assisted da Vinci Surgery techniques and performs rubber band ligation for internal hemorrhoids and Transanal Endoscopic Microsurgery (TEMS) for the removal of rectal tumors and early-stage rectal cancers. He also regularly performs screening colonoscopy for the early detection of colon cancer.
