A Vision Beyond Traditional Care
Frustrated by the limitations of traditional healthcare, Dr. Kostacos set out to create something different—a practice that redefines what it means to truly care for patients. Fueled by a belief in the transformative power of preventive care, she envisioned a model centered around empowerment, access, and deeper connection.

In partnership with Ms.Medicine, Dr. Kostacos designed a practice that makes time for unhurried consultations, fosters open dialogue, and ensures personalized care plans are never rushed or overlooked.

Personalized Care, Elevated Through Concierge Medicine
At Premier Medicine and Wellness, we believe healthcare should be built around you—not the other way around. That’s why we practice concierge medicine, a model that prioritizes time, access, and a deeper physician-patient relationship.
Unlike traditional practices where visits feel rushed and reactive, our approach allows for longer, more meaningful appointments. You’ll have direct access to Dr. Kostacos, same- or next-day scheduling, and a physician who knows your history, your goals, and what matters most to you.
This model isn’t just about convenience—it’s about truly proactive care. We focus on prevention, early detection, and whole-person wellness so you can feel confident, informed, and supported every step of the way.
From coordinating with specialists to offering advanced diagnostics and personalized care plans, we go beyond the ordinary to give you the attention and expertise you deserve.
This is healthcare the way it should be: thoughtful, connected, and centered entirely on you.
