Who We Are
shawnee mission internal medicine and pediatrics doctors

Paul Moore, Jr., MD, Katie Lorentz, MD, and Michael Greenfield, MD, are the Board-certified physicians at Shawnee Mission Primary Care – Internal Medicine & Pediatrics. All dual certified in internal medicine and pediatrics, our physicians work together to provide seamless, expert care for the entire family.

After practicing together for more than a decade, and with a combined 30+ years of experience providing care to children and families in south Johnson County, Dr. Greenfield and Dr. Moore joined SMPC-Internal Medicine & Pediatrics in 2015. Dr. Lorentz joined the practice in 2016 after working as a pediatrician and internist in Palo Alto, California. 

Because our physicians treat patients of all ages, our practice offers a dependable continuum of care from childhood through adulthood, giving you and your family peace of mind. And if you are ever hospitalized, you can count on your physician to be at the hospital, too, making sure you’re getting the care you need to get back on your feet.
