Gwen Holtan

Virtual weight loss coach and health advocate 

A coach who helps her clients achieve sustainable weight loss, improve their health, and live more fulfilling lives through personalized nutrition and lifestyle plans.

She also serves as the health coach for The Heart of Wellness Integrative Medicine, collaborating with Dr. Hillary Bassett, MD, to support patients in achieving lasting healthy lifestyle changes through nutrition, movement, and mindset.

With a background in healthcare, Gwen saw firsthand how preventable health issues overwhelmed the system. Now, she helps clients take control of their health before illness strikes, bridging the gap with health coaching that nurtures both body and mind.

Gwen’s approach combines functional health coaching—developing customized plans based on each person’s medical history, genetics, lifestyle, and environment—focusing on root cause identification, addressing emotional, physical, and physiological barriers to lasting change.

Her coaching goes far beyond food and the scale. Gwen empowers clients to boost energy, improve sleep, balance mood, and build confidence while creating sustainable habits rooted in self-compassion and self-trust. The ultimate success? Clients who feel confident continuing their health journey long after coaching ends.

No dieting. No gimmicks. Just real, flexible solutions designed to help you feel your best, unlock your potential, and show up in your life with more energy, clarity, and purpose.

Leah Casey

Virtual Nutrition Coach and Mental Wellness Advocate

Leah helps clients create healthier, happier lives by blending nutrition, movement, and mindfulness with a deep understanding of mental well-being. With a background in mental health and art therapy, and years of experience coaching CrossFit and fitness, she knows that health is about more than just numbers—how you feel in your body and mind.

Her journey began in 2017 when she realized she was undereating by over 1,000 calories a day and following a restrictive low-carb diet. With the guidance of the Beyond the Box Nutrition® team, Leah learned the power of flexible dieting, fueling her body with more food, not less, and saw dramatic improvements in energy, strength, and mental clarity.

Today, as a compassionate weight loss coach and holistic nutrition coach, Leah combines empathy and accountability to help clients improve their relationship with food, feel stronger, and regain their energy, without restrictive diets or unrealistic plans.

As one client shared:

“She never put me in a box. She never gave me a one-size-fits-all approach. She listened, guided, and helped me every step of the way… Today, I have the BEST relationship with food I’ve EVER had!”

Leah is here to meet you where you are and guide you toward sustainable changes that help you feel your best, inside and out.
