He later founded APEX Brain Centers to combine his ground-breaking rehabilitation approach with a unique patient and caretaker-centered care model.

Dr. Denise Trayford


Dr. Denise Trayford spent many years in integrative health care settings in both New York and Boston working hand in hand with providers from both the traditional and complementary medicine arenas. Being able to bridge the gap between these worlds has given her the ability to relate to clients with virtually any type of health care concern, ensuring their voices are heard and their health care needs are met.

Her undergraduate training in exercise physiology and post-graduate training as Doctor of Chiropractic have given her the unique opportunity to work with clients on a one-to-one basis providing encouragement and constant guidance to assist them in meeting their individual health performance goals and objectives.

In her current role, she directs performance of all neurophysiological testing applications in a safe, friendly environment; which, in turn, direct the individualized treatment programs at APEX Brain Centers.

In her spare time, Dr. Trayford enjoys quality time with her two daughters and dog Titus, camping with the family, travel, and photography in the beautiful mountains of Western North Carolina she calls home.



Traci Turpin grew up in the Smoky Mountains of Western North Carolina. She holds a degree in substance abuse treatment and has worked in the health care community for over 20 years; most recently in the administrative aspects of a large post-acute rehabilitation facility.

Having worked with various patient populations and having served in many roles, Traci has a keen awareness of the care continuum from both the clinic’s and the patient’s perspective. She believes a key part of the healing process is the patient having an active and informed role in their recovery.

Traci enjoys live music and traveling to different cities where she can immerse herself in the sights and sounds of each new place.

While the Smokies will always be home for Traci, she is naturally drawn to the sea.
