Dr. Wimmers has unique experience in microsurgery and immunology. His extensive research utilizing stem cells in hand transplantation has been presented nationally and internationally and was funded by prestigious grants from the U.S. Department of Defense. Years of work in transplantation combined with three years of reconstructive training at the world-renowned Johns Hopkins University have made him an expert in microsurgery. Although he operates on the entire body, his special interests are breast reconstruction (DIEP flap surgery), abdominal wall reconstruction, and peripheral nerve repair. Dr. Wimmers has also developed a ground-breaking surgical treatment for erectile dysfunction. This procedure utilizes nerve surgery techniques to provide a long-term solution for patients with erectile dysfunction caused by nerve damage or interruption. He was invited to present this novel surgical treatment and successful outcomes at the American Society for Peripheral Nerve Surgeries 2021 Annual Meeting.
