MEET THE TEAM
CATHERINE DIVINGIAN (“Dr. D”), MD, PHD
Chief Executive Officer (CEO)
Chief Medical Officer (CMO)
Dr. Catherine Divingian (AKA “Dr. D”) serves as the Chief Medical Officer (CEO) and Chief Medical Officer (CMO) of Operation Phoenix Health, where she provides regenerative medical services.
Years ago, her body was racked by numerous injuries and even premature osteoporosis, disabilities that led her to a wheelchair, along with a box full of pain killers and other prescription drugs. But she learned how to overcome ALL her limitations—both physical and mental—and is now a dedicated tactical hybrid athlete who runs, rucks, and lifts with more dedication and zeal than most people half her age.
Dr. D’s personal journey, marked by physical debilitations and an indomitable spirit, now fuels her drive to help her patients overcome their debilitating conditions. She’s not just a survivor; she’s a strategist, turning past battles into sources of inspiration for patients seeking to break through barriers and overcome their limitations.
LIFELONG PASSION FOR SCIENTIFIC RESEARCH AND INNOVATION
Dr. Divingian is a licensed physician who began her medical career in internal and emergency medicine. However, her passion lied in regenerative medicine where she ultimately established her own practice.
But Dr. D has always had a keen interest in all aspects of health. In addition to her MD, Dr. Divingian holds a PhD in Health Psychology and an MS in Pharmaceutical Sciences. She is also an ISSA-certified Sports Nutritionist, an ISSA-certified Corrective Exercise Specialist, and an NSCA-certified Tactical Strength and Conditioning Facilitator. Collectively, her extensive education and experience make her an innovative powerhouse as the company’s Chief Medical Officer.
PIONEER OF REAL-WORLD CLINICAL APPLICATIONS
Since the 1990s, Dr. Divingian served in various academic roles as a professor and research scientist. But her journey was never about the titles and accolades; it was about rolling up her sleeves and diving into the trenches.
Her investigations have spanned the medical-health spectrum and included innovative proposals on wearable battlefield triage sensors and cardiac stress-detection devices; improved policies for female combat readiness; rapid community response to medical disaster; post-traumatic stress syndrome and delayed wound healing; the effects of aspartame on the brain; complex post-traumatic stress syndrome in first responders; the physiology of diabetes; and sudden cardiac events in firefighters.
Despite her scientific training, Dr. Divingian is never one to be satisfied in the lab or the university. She prefers to deal with the real-world stuff. Whether that be the injuries and traumas she treated in the hospital emergency room or the chronic pain of the men and women she treats today, Dr. D never stops.
MEDICALLY TRAINED MILITARY VETERAN
Dr. Divingian’s background is a testament to her dedication and impact. As a former Medical Service Corps officer in the U.S. Navy, she conducted research in operational medicine and telemedicine, produced educational materials on radiation safety, and led crucial disaster medicine drills on the USNS Mercy.
After more than two decades, she returned to duty as a Reserve Soldier in the Army Medical Corps. Now, Dr. Divingian has combined what she has learned from her medical and military training toward helping her patients rise above their perceived limitations and reclaim their STRENGTH, VITALITY, and DIGNITY.
AUTHOR AND CO-AUTHOR OF NUMEROUS PUBLICATIONS
Dr. Catherine Divingian is the author and co-author of several life-changing books and other publications, including Sleep Victory: How to Defeat Chronic Sleep Loss and Finally Get the Rest You Need; Optimizing Combat Readiness in Female Military Personnel; The Spartan Diva: The Ultimate Get Lean Diet Plan; Real Talk, Real Women; and When You are Stuck in a Rut. She was also published in Medscape, EM Resident (“Firefighter Down!”: Sudden Cardiac Events and Risk Mitigation for Emergency First Responders); Fitness & Physique magazine (Going Beyond Fat-Loss); and Navy Medicine journal (Leading Fitness), among others.
DARIUS CREED
Chief Educational Advisor (Consultant)
Darius Creed is the Chief Educational Advisor for Operation Phoenix Health. As the company’s leading consultant, his responsibilities are mainly focused on regenerative medical research, patient communication, and educational training. His expertise is especially relevant to the sales department, the first point of human contact for our patients.
Unofficially, he devotes additional time to the company’s evolving vision, brand design, and strategic leadership. He is also the primary creative force behind the development of our company’s name, logo, ethos, and trade dress.
Creed has devoted most of his life to investigating the multifaceted domain of human potential, where he combined his research of exercise science, nutrition science, performance psychology, body language, and regenerative biologics into a unified discipline that is now being leveraged towards education, communication, and transformation. These actionable outcomes, both for our company and our patients, are his primary motivations behind his role in Operation Phoenix Health.
ADVANCED EXPERIENCE AND EXPERTISE IN HEALTH AND FITNESS
Creed has been a strength and conditioning trainer and peak-performance coach for more than two and a half decades. Back in 2000, he first started volunteering coaching services to U.S. Marines to enhance their physical performance. Over the years, he has provided training, classes, and consultation to countless people from a wide range of backgrounds, with clients ranging from teenagers to senior citizens.
In 2007, Creed participated in the international military-wide Crews Into Shape contest and led an eight-person team that collectively lost over 50 lbs. of weight. His group had the distinct honor of being first-place winners out of hundreds of teams composed of thousands of competitors.
Creed has authored and published numerous health and fitness articles. He is also the primary author of the book Sleep Victory: How to Defeat Chronic Sleep Loss and Finally Get the Rest You Need, released in 2024.
Formerly an ACE-certified Personal Trainer and USAW-certified Sports Performance Coach, he continues to maintain his certification as a Tactical Strength and Conditioning Facilitator with the National Strength and Conditioning Association (NSCA).
In addition to his fitness certifications, he earned his Bachelor of Science in Health Science and graduated with honors (summa cum laude). He also completed his second master’s degree, which is in Sport (Performance) Psychology, the study of psychological performance.
INNOVATIVE MEDICAL INVESTIGATOR
Creed’s coaching, while focused primarily on diet, exercise, mindset, and regenerative biologics, has repeatedly led to surprising health outcomes beyond his clients’ expectations, including complete reversals in conditions such as tendinopathy, osteoporosis, chondromalacia patellae, hypertension, pre-diabetes, chronic fatigue syndrome, osteoarthritis, degenerative disc disease, cellular agglutination, urinary trac t infections, and even stage-3 chronic kidney disease. These regenerative outcomes were often accompanied with supportive medical documentary evidence.
In 2012, Creed disclosed his microscopic before/after blood analyses to the Human Performance Laboratory of the Naval Special Warfare (NSW) Group 2 Training Detachment (TRADET) and revealed definitive proof of the adverse agglutinating effects of gluten on red blood cells.

In another example with the same military unit, he contacted the lead physical rehabilitation specialist and shared his investigation of platelet-rich plasma (PRP), which at the time was still a relatively obscure method to address tendon degeneration, a technique that was quickly adopted as an effective treatment modality for injured members of the Naval Special Warfare Development Group (SEAL Team Six). His success with regenerative solutions is directly correlated with his commitment to scientific research and unconventional medical investigation.
MEDICALLY TRAINED MILITARY VETERAN
A former Fleet Marine Force Corpsman (infantry medic), Creed has over 14 years of training and experience in military trauma field medicine. During his active-duty tenure, he devoted nearly five years attached to several infantry combat units with the 2nd Marines, 2nd Marine Division and has been deployed to several locations in the Middle East where he participated in various missions including Operation Iraqi Freedom. Creed concluded his active-duty service with Naval Special Warfare, Group 2 Training Detachment, where he provided medical care for Navy SEALs and their instructors during pre-deployment training operations.
Today, Creed continues his military service part-time as an Infantryman in the Florida Army National Guard. Unquestionably, his medical and military experiences irrevocably influenced and enhanced his perspective on health and human performance, which he now leverages to help men and women to achieve RADICAL transformations.
