    Provider's Bio

    I am an internationally trained dermatologist and Mohs micrographic surgeon with expertise in cutaneous oncology, skin cancer surgery, and appearance medicine. I am patient-centered and believe in compassion when caring for my patients and their dermatologic concerns. When you become my patient, you will also experience the quality care from the dermatology nurses and clinical support well-beyond the traditional patient encounter. I look forward to working with you.

    I grew up in Indianapolis, but I have lived all over the United States and abroad. After completing my surgical fellowship in New Zealand, I moved to the Mankato area. I enjoy spending time outdoors hiking, walking and exploring local restaurants and vineyards.
