About BeActivated

What if everything we knew to be true was false?

Is a question Douglas Heel begins with. Are we willing and able to let go of things that have served us for some time and no longer benefit us? 


The BeActivated system is a groundbreaking neuromuscular activation system developed by South African physiotherapist Douglas Heel. This innovative method employs simple hands-on techniques to 'reset' the body's natural sequencing patterns, often starting with breathing and muscle activation. By restoring proper function to key muscles, the BeActivated system enhances movement efficiency, reduces pain, prevents injury, and unlocks greater performance. Many clients experience quick, powerful changes in strength, mobility, and overall well-being, ultimately contributing to their Parasympathetic Performance.

The Framework Begins With Breath

The primary objective of the BeActivated system and its associated neuromuscular activation techniques is to help individuals transition out of the fight-flight-freeze responses that our Nervous System can often become trapped in. The performance you experience is a direct result of this shift towards Parasympathetic Performance.

The system as a whole

In the BeActivated system, we analyze the system as a whole rather than focusing on individual parts. This approach, which includes specific neuromuscular activation techniques, provides us with a framework for client sessions that prioritizes assessment-intervention-assessment. This structure helps us determine the effectiveness of our work and enhances Parasympathetic Performance.

The Athlete in Everyone

We meet everyone where they are! If you are ready to take your health into your own hands, the BeActivated system can effectively guide you closer to high-level wellness and performance, regardless of where you are on this continuum. By utilizing neuromuscular activation techniques, we help shift your body towards optimal functioning.

About BeActivated and Neuromuscular Activation

We prioritize getting people out of their minds or thinking brains, and into their bodies and how they feel, utilizing the BeActivated system to enhance this process. A key component of the neuromuscular activation techniques we employ is allowing the client to walk after a shift occurs on the table. This enables the mind/body to integrate and process the change effectively, promoting Parasympathetic Performance. We highly value the subjective information gained from clients.

The Mission

I founded Parasympathetic Performance out of both personal struggle and discovery. For years, I searched for solutions to elevate my performance abilities and confidence. I have experienced firsthand the frustration of navigating the current landscape of health and human performance, particularly with the overwhelming amount of information available on the topic. Throughout my journey, I have navigated numerous personal injuries, most of which were entirely avoidable, and have often had to return to the drawing board. I always knew there was more to learn—something better yet to be discovered. This interest, along with the obstacles I faced, led me to develop what I believe is an all-encompassing system that will continue to evolve alongside Parasympathetic Performance and myself.


I have had the privilege of learning from incredible teachers and mentors, which fueled my passion for helping others unlock their true potential through neuromuscular activation techniques. Eventually, I no longer felt the need to continue searching. I found what worked, delved deep into it, and was amazed at how effective it continued to be. I began to experience a newfound ease in life that did not require an extensive morning routine or forced discipline for minimal improvement. My approach combines objective assessment with subjective experience, ensuring each client’s progress is measurable, sustainable, and meaningful.


I hold a degree in Applied Exercise Science from Northern Michigan University, am a Certified Strength and Conditioning Specialist (CSCS), a Licensed Massage Therapist (LMT), and a Level 1 & 2 BeActivated Practitioner. More importantly, I have personally experienced the benefits of this work—engaging in activities like running, jumping, skiing, boxing, mountain biking, and more in ways I never thought possible.


My mission is to guide others in experiencing that same freedom. I strive to help clients not only improve their movement but also rediscover joy in their bodies, build lasting resilience, and leave each session feeling empowered, confident, and equipped with the tools necessary for continued growth—both with and without my guidance.
