Lawrence Koning, M.D.
Lawrence K. Koning, MD, FACOG
“For the 30-plus years that I’ve been an obstetrician-gynecologist, I’ve always been motivated to provide the highest standards of care. In truth, it’s etched into my core personal values. I watched my father, a family physician for more than 50 years, dedicate himself to helping others. I was raised with the principle that it’s important to make a valuable contribution…and to really strive to do it to the highest level. For me, it was almost natural that I became a doctor — not simply because my father was one, but because I share his desire to make a positive difference in people’s lives.
Today, that sense of compassion and commitment is as strong as it was when I started medical school and when I opened my own OBGYN practice. After delivering more than 7,000 babies and caring for many thousands of women, I have a high degree of experience. Yet, to provide today’s highest standard of care, I’ve also dedicated myself to performing advanced, state-of-the-art procedures, as well. My goal is to provide premier OBGYN care that meets the needs of every woman while exceeding their expectations.”
