Our People
Kelly Clark, MS, ACNP-BC
Founder & Owner
Kelly is the owner and founder of Medical WeightLoss & Wellness, Inc. She earned both her undergraduate and Master’s degrees in Nursing from Marquette University in Milwaukee, where she became board certified in Adult Acute Care. Much of her nursing career was spent in emergency medicine. After completing her master’s degree, she served as a Nurse Practitioner in the emergency department at Froedtert Memorial Lutheran Hospital through the Medical College of Wisconsin.
Driven by a passion for prevention and long-term wellness, Kelly recognized the opportunity to make a greater impact on patient health outside the ER. This inspired her to establish Medical WeightLoss & Wellness, Inc., where she now combines her clinical expertise with a deep commitment to health education. Her mission is to empower patients through sustainable lifestyle changes.
Kelly now lives in Wisconsin with her husband, Matt, her stepdaughter, Gabby, and their three dogs—Asti, Pearl, and Millie. She is also the proud mom of two grown sons, Jack and Brady.
