Our Team At EBHC Innovative Solutions For CIRS Disease

Shane Lashley

Shane Lashley, ABAAHP, MBA, M.Mgt.

Clinic Director

Shane collaborates with the medical team and each EBHC patient so that their personalized medicine program aligns with their needs and goals. Shane’s passion for health began after he experienced his own health crisis in 2008 that disrupted a successful business career. He became passionate about helping empower others who experience complex or chronic diseases.

Shane has completed the most advanced and comprehensive training in mold, Lyme, and biotoxin-related illness known as Chronic Inflammatory Response Syndrome (CIRS).  He serves as a consultant to both clinicians and patients regarding the assessment and treatment process, and he serves as a consulting expert to law firms engaged in litigation related to biotoxin exposures.

Shane is not a physician and does not diagnose or treat EBHC patients. He is Board-certified as an anti-aging Health Practitioner by the American Academy of Anti-Aging Health Practitioners. He is in the final stages of completing an advanced fellowship in Metabolic and Functional Medicine.

Shane is also pursuing a Master of Science in Health Sciences (MSHS) degree in Integrative Medicine at The George Washington School of Medicine & Health Sciences.

Prior to entering the health profession, Shane earned his Master of Business Administration and Master of Management in Corporate Finance, both through the University of Dallas Graduate School of Business.  For nearly two decades, Shane served as an international business consultant to companies ranging in size from start-ups to thousands of employees.
