I was a Clinical Pharmacist, mostly in Infectious Diseases and Nutritional Support in Hospital ICUs for about 20 years prior to going to Medical School at Medical College of Wisconsin. I also completed my Internship and Residency at The Affiliated Hospitals of the Medical College of Wisconsin in Internal Medicine/Pediatrics, and served as Chief Resident during my final year. I am a Board Certified Fellow in Both Internal Medicine and Pediatrics and love giving quality, compassionate care to my patients in both specialties. I am also close to Board Certification in Cosmetic Medicine. I enjoy going on Mission Trips to Central America and have learned Spanish doing so and serve the Spanish population in my area. Most all areas of medicine interest me. I have recently board certified in Addiction Medicine

Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.

No: You are not likely to get tetanus from wood splinters but your vaccination is good for ten years and is current. You should seek help to get the splinter out before it gets infected.
