Dr. Shara Posner
A College Park Scholar at the University of Maryland, Dr. Shara was studying for her Bachelor of Science in Kinesiology when she first encountered chiropractic. As an intern at a chiropractor’s office, she saw people walking into the practice bent over in pain but leave happy and feeling well. Since then, Dr. Shara has been hooked on the idea of living a more health-minded lifestyle. “I don’t have a deficiency of pain medications in my body. We get to the source of the problem and use the body’s own abilities to heal.” Read more about Dr. Shara Posner »

Marcus Quiaiot NP
With more than a decade of experience in healthcare, I bring a unique combination of critical care expertise, advanced practice experience, and a passion for proactive wellness and longevity medicine.
I began my nursing career in Florida in 2012, working in trauma care and vascular access. I later continued my clinical journey in Washington, DC, as a critical care nurse, caring for patients with complex and life-threatening conditions. These experiences gave me a strong foundation in clinical medicine and taught me the importance of precision, prevention, and truly understanding each patient’s individual needs.
In 2021, I became an Adult-Gerontology Nurse Practitioner, specializing in critical care and palliative medicine. Caring for patients through some of the most serious and defining moments of their lives profoundly shaped my approach to healthcare and reinforced the importance of preserving health and quality of life long before illness occurs. Today, I bring that clinical experience into the outpatient setting, where my focus is wellness, preventive health, healthy aging, and longevity.
My philosophy is simple: healthcare should be personalized, proactive, and centered around the individual. Rather than taking a one-size-fits-all approach, I take the time to understand your health history, goals, lifestyle, and unique needs to develop a personalized wellness strategy.
Through a medically supervised wellness-style approach, my goal is to provide a more thoughtful and individualized healthcare experience—helping you optimize the way you feel today while building a foundation for better health and vitality for years to come.
