Genetic Testing and Review

Through an in-depth review of your genetic blueprint, bioenergetic patterns, and personal health history, I evaluate how your Endocannabinoid System (ECS) is communicating and regulating your body’s internal balance. Because the ECS acts as the body’s master regulatory system—guiding stress response, inflammation, hormones, and repair—these insights allow me to translate your DNA results into a personalized at-home protocol. Your plan may include targeted nutrition, plant compounds, breathwork, sensory inputs, and lifestyle practices designed to gently restore balance and support your body’s natural intelligence. Genetic Testing, Review, & Protocol

We're designed different.

The Endocannabinoid System is one of the most important biological systems regulating human health—yet most people have never been taught how it works.

At MainSpring Well Center, founder Dani Fontaine has developed a unique and innovative approach to understanding and supporting the Endocannabinoid System (ECS)—one of the body’s most important regulatory networks responsible for maintaining physiological balance.

Our work is centered around precision wellness, integrating advanced genetic testing, ECS science, biofield measurements, energy-based technologies, and plant-based therapeutics to help restore balance within the body’s master regulatory system.

Every individual has a unique biological blueprint. By exploring your personal ECS profile, we gain deeper insight into how your body responds to stress, inflammation, nutrition, and environmental influences. Understanding these patterns allows us to uncover why your body functions the way it does.

Using this information, we develop personalized wellness protocols tailored specifically to your genetics, physiology, and lifestyle, helping you move toward more consistent states of coherence, resilience, and long-term vitality.

At MainSpring, we believe that when you understand your body’s natural design, you gain the ability to support it in returning to its optimal state of hOMeostasis and becoming the best and healthiest version of yourself, that you deserve to experience.
