Founders / Leadership
Dr. Frank J. Welch, MD, MSPH, FACPM, ABAARM — Medical Director | Longevity & Regenerative Medicine
With a background in Public Health and board certification in Anti-Aging Medicine, Dr. Welch moves beyond treating symptoms. He focuses on optimizing the biological foundations—hormones, metabolism, and cellular health—to extend your healthspan.
Todd J Ashcraft— CEO | Strategy & Performance
Todd bridges the gap between clinical data and real-world application. His focus is on the operational excellence of OHI, ensuring every client receives a seamless, data-driven experience that translates medical insights into tangible life improvements.
Rainey Ashcraft — Fitness Director | Strength & Longevity Specialist
Rainey leads the 'Strength-First' mission. She designs functional movement protocols that protect lean muscle mass—the most critical organ of longevity. Her approach ensures that as you age, you aren't just living longer, but staying powerful and capable.
Clinician-guided options when appropriate
For eligible clients, prescription-based therapies may be considered as part of a comprehensive plan—never as a stand-alone solution. We focus on shared decision-making, monitoring, and long-term sustainability.
Important expectations
Results vary. The goal is not “eternal youth”—the goal is better function, better health markers, and better quality of life when treatment is clinically appropriate.
Information on this website is for educational purposes and is not medical advice. Services are provided by licensed clinicians where appropriate. Individual results vary. Always consult a qualified healthcare professional for diagnosis and treatment.
At Oak Health Institute, our core services—HRT & peptide therapies, medical weight loss, and functional fitness—are designed to work together because research shows the greatest improvements in long-term health occur when hormones, metabolism, and muscle are addressed as a system, not separately.
Medically guided hormone and peptide therapies can support energy, recovery, and body composition when appropriate, while modern weight-loss treatments improve metabolic health—but without strength training, muscle and performance are often lost.
What sets Oak Health Institute apart in the Raleigh area is our physician-led, strength-first model, where medical care and functional fitness are fully integrated to help clients build resilience, confidence, and measurable health as they age.
