A note about our provider transition

Our office has recently undergone a change in providers, and our team remains committed to providing high-quality, personalized primary care services to residents in and around De Soto. Steven Rettinger, MD, and Lauren Fields, APRN-C, have joined the practice and Charissa Richard, DO, has left. James Boyes, RPA-C, remains at the practice.

If you were formerly a patient of Dr. Richard and need to establish care with another primary care provider, the team at Shawnee Mission Primary Care (SMPC) - De Soto will be glad to help you find a provider who is right for you. To schedule an appointment with Dr. Rettinger, Jim or Lauren, or if you have questions about these providers, please call our office at 913-789-3961. If you prefer to transfer your primary care relationship to a provider at another location, SMPC has offices conveniently located throughout Johnson County. To take a short survey that will help you determine which SMPC providers best match your health goals and your personal wellness philosophy, visit

If you have any questions during this transition, please call our office at 913-789-3961.
