About Doctor Slim Med Spa in Lewisville, TX
Local Care Built Around Real People
At Doctor Slim Med Spa, we know that choosing a med spa is personal.

Our Lewisville location makes care convenient for patients throughout Flower Mound, Highland Village, Lake Dallas, Corinth, and nearby North Texas communities, but what matters most is how patients feel when they walk through the door: heard, respected, and supported.

Dr. Reno’s approach blends medical oversight with practical, patient-centered guidance. At Doctor Slim, she focuses on regenerative procedures, longevity-focused peptide programs, and supportive care for patients using medical weight loss therapies.

Before joining Doctor Slim Med Spa, Dr. Reno founded and directed Performance Sports Medicine in Dallas, where she cared for athletes, performers, active adults, and complex musculoskeletal cases. Her experience includes treating pediatric and professional athletes, dancers, soccer players, gymnasts, martial artists, cyclists, and high-level recreational athletes. She has also served as a team physician for multiple athletic organizations and has extensive experience developing customized rehabilitation and corrective conditioning programs.
What makes Dr. Reno especially unique is her background as a professional dancer, choreographer, and educator before entering medicine. This gives her a deep understanding of movement, body mechanics, performance demands, and the importance of staying active at every age.
At Doctor Slim Med Spa, Dr. Reno is excited to support patients through a thoughtful, medically guided approach to longevity, regenerative wellness, peptide therapy, and body transformation.
