Tomo Marjanovic, founder and CEO of Aspire Rejuvenation Clinic, today announces the release of his book, "Operation Optimal: Health, Wellness, & Becoming Your Best You," now available at OperationOptimal.com and major retailers. The book draws on Marjanovic's unlikely path from decorated police officer to healthcare entrepreneur, sharing his personal journey of taking control of his own health after the medical system failed to address the root cause of his hormonal issues.

Why it matters

Marjanovic's mission is to make hormone optimization accessible to veterans and first responders, a population whose careers systematically damage their hormonal health and who are routinely underserved by existing systems. The book aims to empower readers to take radical ownership of their health and become their best selves.

The details

After spending 12 years in law enforcement in Ohio and Florida, earning the Public Safety Medal of Valor, Marjanovic experienced firsthand how chronic night shift work and occupational stress quietly destroyed his hormonal health. When the medical system offered him antidepressants instead of addressing the root cause, he decided to take control of his own health. Marjanovic earned his certification in Advanced Bioidentical Hormone Replacement Therapy, left law enforcement in 2018, and founded Aspire Rejuvenation Clinic in Orlando in 2019 with maxed out credit cards and no outside funding.

  • Marjanovic founded Aspire Rejuvenation Clinic in Orlando in 2019.
  • COVID-19 hit three months after Aspire Rejuvenation Clinic opened in 2019.
  • Aspire Rejuvenation Clinic is expanding into Cleveland and Dubai with a franchise model planned for late 2026.
