Welcome to the website of Advanced Surgery. Our board certified Rockville, Maryland surgeons, Glenn Sandler, MD and Craig Colliver, MD offer a combined 35 years of experience specializing in the management of breast disease and breast cancer, laparoscopic abdominal surgery, hernia repairs, gallbladder removal and hemorrhoid surgery.
Our Maryland doctors also specialize in the treatment of skin and soft tissue diseases, such as melanoma, lipomas, pilonidal cysts and sebaceous cysts.
The philosophy of our practice is based on patient care, physician availability, and dedication to surgical education and innovation. We continue to believe that these principles help our practice to deliver the highest quality surgical care for our patients.
Advanced Surgery has offices in Rockville, MD, and our physicians are available to see patients for office appointments Monday through Friday and available on-call 24 hours a day, 7 days a week.
