Alexandra Mattingly

Leadership


With a foundation in biology, environmental sciences, and art, Alexandra brings a thoughtful and multidisciplinary approach to her role overseeing clinical operations at Longevity Centers of America. She manages inventory systems, supports in-office treatments, and handles much of the clinic’s branding and graphic design work. She especially enjoys assisting with regenerative therapies, particularly using VSELs with the Song laser. She learned the technique firsthand while training at Dr. Todd Ovokaitys’ clinic in California, where the therapy was originally developed. This therapy uses healing frequencies to activate the body’s own very small embryonic-like stem cells, allowing for deep, internal repair with precise cellular targeting. Her attention to detail and understanding of both science and aesthetics help ensure that patients receive thoughtful, effective care from start to finish.

Integrative Healing Meets Longevity Science

Chloe Kessel

Hippocrates Team


Chloe Kessel, MSN, APRN, FNP-C, grew up in West Palm Beach, Florida. She earned her BSN from the University of Florida and her MSN from Chamberlain University. Her clinical background as a nurse was primarily based in adult and pediatric emergency departments. Before transitioning to integrative medicine, she practiced both acute care and outpatient cardiology as a nurse practitioner. This trajectory provided her with an understanding of the profound complexities, but also the limitations of reactive healthcare. Her approach at The Longevity Center is defined by a compassionate yet analytical process that prioritizes evidence-based, individualized protocols over standardized symptom management. Rather than addressing health concerns in isolation, she strives to unearth the underlying physiological drivers of a patient’s chief complaint. She views each patient as a unique biological system, necessitating a customized strategy to reach their specific health goals. By merging her traditional clinical experience with a focus on regenerative and integrative principles, she strives to ensure that every patient receives a comprehensive, evidence-based roadmap to long-term wellness.

Carly Ehrlich

Hippocrates Team


Carly plays a key role in supporting patients throughout their time at The Longevity Centers, helping ensure a smooth and welcoming experience from the moment they walk in the door. Her interest in health and wellness is personal: after facing health challenges that traditional medicine struggled to resolve, she found answers through her own care experience with Dr. K, eventually discovering that mercury toxicity was the root cause of her symptoms. That journey to relief now shapes how she supports other patients navigating their own paths to wellness.

Frequently Asked Questions

Who leads the medical team at The Longevity Centers of America?

The Longevity Centers of America is led by Dr. Benjamin Kosubevsky, DO, a board-certified osteopathic physician specializing in regenerative and integrative medicine. He earned his Doctor of Osteopathic Medicine degree from the Lake Erie College of Osteopathic Medicine and holds board certification through the American Academy of Stem Cell Physicians. Kyle Hulbert serves as CEO, overseeing operations across all locations.

What credentials do the clinicians at The Longevity Centers of America hold?

The clinical team includes a board-certified osteopathic physician, board-certified nurse practitioners holding Master of Science in Nursing degrees, and registered nurses with acute and critical care experience. Providers have trained at institutions including the Lake Erie College of Osteopathic Medicine, the University of Florida, the University of South Carolina, and Chamberlain University. All therapies are administered by licensed healthcare professionals with certification appropriate to the treatments they provide.

Are treatments administered by licensed medical professionals?

Yes, every therapy offered by The Longevity Centers of America is administered by a licensed healthcare professional holding appropriate certification, under physician-led clinical oversight. Intravenous therapies, regenerative injections, hormone protocols, and other therapies are delivered by clinicians whose scope of practice includes those procedures under applicable state licensure.

What training do the clinicians have in regenerative and longevity medicine?

Clinicians combine conventional medical training with advanced study in regenerative and integrative protocols. Dr. Kosubevsky holds board certification from the American Academy of Stem Cell Physicians and has developed proprietary EBOO ozone protocols. Members of the clinical operations team have trained directly with the developers of specific therapies, including VSEL protocols learned at the California clinic where the technique originated. Nurse practitioners on staff bring prior experience from intensive care, emergency medicine, and cardiology.

Will I see the same provider at every visit?

Patients are assigned to a clinician at their chosen location and see that same provider for consults throughout their care plan, which supports continuity in reviewing results and adjusting protocols. Therapy sessions themselves may be administered by a different member of the clinical team, all working from the same plan established with your provider. Advanced regenerative protocols are developed and supervised at the practice level by Dr. Kosubevsky, so patients receive the same clinical framework regardless of which clinic they visit.

How do I schedule a consultation with a specific provider?

Consultations can be scheduled online through the appointment page, where patients select a location before booking. Patients searching for a “longevity doctor near me” in Greenville, South Carolina or in the West Palm Beach area can request a particular provider in the appointment notes, and the patient relations coordinator for that clinic will confirm availability. New patients typically begin with a diagnostic consultation before any therapy is scheduled.
