Office Staff

Tiffany is a Registered Medical Assistant with over 30 years of specialized experience in cardiovascular medicine and neurology. A deeply devoted woman of faith and a North Carolina native trained at Kings College in Charlotte, she combines clinical and diagnostic precision with a deeply personalized touch at our integrative health center.

You will never feel like just another number to Tiffany; she doesn't just punch a 9-to-5. As the warm, welcoming heart of the practice, she treats everyone like family—knowing every patient by name and routinely following up off-hours as part of her patient advocacy to ensure nothing slips through the cracks. Away from the office, she cherishes time with her family, nieces, and nephew.

As the welcoming voice and steady hands behind our patient flow and clinical operations at this integrative health center, Ruth brings decades of seasoned medical expertise in cardiovascular medicine to Premier Cardiovascular Care. Operating seamlessly as a medical assistant, phlebotomist, and front office administrator, she ensures every patient's journey—from initial scheduling to in-office throughput—is smooth, efficient, and deeply reassuring. Beyond her rigorous clinical background, Ruth is exceptionally multicultural, speaking English, Hindi, and Fijian. She is a strong advocate for patient advocacy and, outside the clinic, treasures quality time with her family while feeding her passion for international travel.

Cardiovascular care involves far more than just the physical heart—it encompasses the stress of a diagnosis and the challenge of navigating life after a cardiac event. Reba Milbourne Holley, PhD, brings a deep background in human behavior and wellness to Premier Cardiovascular Care, a leading integrative health center, as our dedicated health and lifestyle coach. Operating strictly in a coaching capacity, she bridges the gap between medical guidance and daily living, helping patients master stress recovery, nutritional navigation, and sustainable habit formation. As a trusted extension of our practice, Reba provides the unhurried support, accountability, and confidence-building you need to thrive outside the exam room. For patients seeking a more private, individualized setting, she also offers dedicated one-on-one sessions through her private practice, Wellbound Consulting, emphasizing patient advocacy and personalized care.

As a national speaker, published author, and experienced principal investigator, he upholds ongoing faculty affiliations with prestigious institutions, including Yale University, the University of North Carolina, and Wingate University.
