Professionally Dr. DeMar and Dr. Knoll are the only surgeons in the area who do laparoscopic inguinal hernias and are certified wound care specialists. They are both experts in minimally invasive (laparoscopic) surgery. They take pride in taking care of their patients using a team approach thereby providing 24/7 coverage of their patient’s needs. This approach, unfortunately has become increasingly uncommon in today’s medical environment. They remain committed to consistently and dependably providing for their patients despite the growing obstacles brought to bear by insurance companies and the government.
