General Surgery

Our general surgeons specialize in removing cancerous tumors of the breast, liver, pancreas, gastrointestinal tract, colon and rectum. We also treat a wide spectrum of benign surgical conditions like inguinal and ventral hernia repairs, gall bladder surgeries and appendectomies as well as bariatric surgeries.

Mohs Micrographic Surgery

Mohs micrographic surgery is a procedure to remove skin cancers (basal cell carcinomas and squamous cell carcinomas). Mohs surgery is used mostly for high-risk cancers on the head and neck, where keeping normal tissue around the cancer is important. To learn more visit the Dermatology page.

We also have regional expertise in the surgical management of gastroesophageal reflux disease, hyperhidrosis and congenital chest wall deformities. We strive to stay current with evolving practices by participating in and supporting research, and the education of students, residents and fellows at both the St. Joseph’s and St. Michael sites.

Urology Surgery

Our urologists provide consultation, diagnosis and treatment for cancerous (malignant) and noncancerous (benign) diseases of the urinary tract including prostate, kidney and bladder cancer, urinary incontinence, benign prostatic hyperplasia and kidney stones. We perform minimally invasive (laparoscopic) surgery, resulting in less discomfort and bleeding and a faster recovery than conventional surgery.
