ninaChristina “Nina” Raymond, A.C.E. Personal Trainer, AIS Therapist LMT (#39331)

Nina has college degrees in Botany and Wetland Ecology, and she used that knowledge in her professional career to restore native vegetation on disturbed lands. Her hobby is learning native medicinal and edible plants.

For the past 15 years, Nina’s primary modality has been Active Isolated Stretching (AIS). She was inspired to master AIS after Aaron Mattes (inventor of AIS), in just 2.5 hours, applied AIS therapy to successfully eliminate Nina’s humpback that resulted from auto accidents. With her new lease on life, Nina then apprenticed with Mattes for 3 years in his clinic to master his work. She is an assistant instructor at Mattes’s AIS seminars and teaches AIS classes for specific needs, such as yoga preparation, rehabilitation, posture improvement, and athletic conditioning.


chantellChantel Hormuth, BS, LMT

Chantel Hormuth graduated from the University of New Orleans with a Bachelor of Science in Human Performance and Health Promotion. Diagnosed with Chron’s Disease at 16, Chantel has since developed an interest in nutrition and wellness for over 30 years. Before turning 19, she had three intestinal surgeries leaving her with no core strength and poor posture. Her first introduction to yoga came from the Jane Fonda exercise album she used to do as a teenager in her living room. Those exercises became part of her daily life for many years to come.

“My first yoga class at the YMCA in Asheville, NC, was not a hit at all. I didn’t know what I was doing and there were too many students for any individualized instruction. A couple of years later, I tried it again in Hawaii where I was living at the time” Chantel recounts. “As a new mom, free childcare offered by YMCA was a reason to return there regularly. But as she recalls :

“No elliptical machine or crunches had any effect on my pooch, despite ongoing exercise”. One day she noticed how sweaty yet relaxed people were coming out of the yoga class and decided to try again. “I fell in love with the teacher’s lighthearted style, her openness, and her compassion, despite her young age.” That class was so great that she soon gave up elliptical and crunches for downward dogs and pigeons.

“This practice transformed me: body and mind. With a steady yoga practice came not only a strong core and impeccable posture but also stillness of mind. When the opportunity to participate in a yoga teacher training came up a few years later, Chantel took it thanks to endless support from a dear friend. She completed her training with Yoga Hawaii on Oahu in 2005.

Years later now living in Tallahassee, her position as a state employee felt incompatible with her aspirations for a more authentic way to earn a living. Chantel then embarked on the journey of becoming a licensed massage therapist, a path she felt would complement her love of yoga.

Thus Chantel attended CORE School of Massage and Bodywork in Tallahassee and became a licensed massage therapist in June 2009. She took advanced classes in medical massage, Thai yoga massage, lymphatic drainage, Indian Head Massage, and myofascial release bodywork.

She has also had the opportunity to be a model for a therapist completing the 10 sessions of Structural Integration training. This experience informs her own massage practice she enjoys calling “therapeutic relaxation”.

“I want my client to feel safe, supported, and even loved. When receptive, the client benefits from this wonderful transfer of energy and healing begins through release of oxytocin and stimulation of the parasympathetic nervous system.”
