Your Path to Healing, Vitality, and Peak Performance


Choosing Nikki as your coach means stepping onto a personalized, regulation-first path to healing and performance. Before adding more effort, you’ll learn to restore balance to your body’s main operating system, the fascial matrix, so every cell can communicate, repair, and thrive. Your program is built around your unique blueprint, weaving together fascia focused movement, nutrition, breathwork, gut health, hydration, sleep and trauma informed self-regulation to create lasting change from the inside out.

With over 25 years of lived experience healing her own body and guiding thousands of clients with a 90% success rate, Nikki brings both science and somatic wisdom to the table. She doesn’t chase symptoms or prescribe quick fixes. Instead, she helps you attune to your body’s natural intelligence—retraining your system to regulate, rebuild, and return to its original rhythm of health, strength, and vitality.

What to Expect


Relief — Regulate First

Repattern flow and communication through the fascial and nervous systems with personalized myofascial stretches, ELDOAs, and lifestyle recalibration. As the fascial matrix rehydrates and the stress response resets, pain eases, hormones rebalance, chronic conditions lose their grip, and mental and emotional wellbeing are restored. This is where your body’s ability to change begins.

Release — Repattern Through the Fascial Matrix

Integrate fascia-focused strength and mobility practices that retrain your body’s tension and tone from the inside out. Through precise, fascia-normalizing movement and nervous system awareness, you’ll rebuild strength, coordination, and postural integrity while re-educating your body’s main operating system.

Resilience — Rewire for Longevity

Adopt advanced regulation techniques and daily self-care rituals that stabilize your fascial-nervous system connection. Learn to respond—not react—to stress, restoring the body’s natural adaptability, rhythm, and capacity for recovery. This is where freedom, resilience, and longevity become your new baseline.

Who can benefit from coaching with Nikki


  • Perimenopausal and Postmenopausal Women – Reconnect and Rebalance

    Hormonal transitions can amplify fascial stiffness, inflammation, and nervous-system dysregulation—showing up as hot flashes, anxiety, brain fog, or joint pain. Nikki’s approach restores fascial hydration, improves circulation, and helps regulate stress and sleep cycles, allowing your body to regain rhythm, resilience, and hormonal harmony through every stage of midlife and beyond.

  • Athletes – Regulate for Recovery and Performance

    High training loads and repetitive movement patterns can dysregulate the fascial and nervous systems, leading to pain, tightness, and fatigue. Nikki’s fascia-focused recovery and performance program helps rehydrate and realign the fascial matrix, regulate the nervous system, and optimize energy output. You’ll move more efficiently, recover faster, and extend your athletic longevity.

  • Working Professionals and Students – Repattern for Posture and Focus

    Hours at a screen or carrying heavy loads pull the body out of alignment and into chronic tension. Through fascia-friendly movement and nervous-system regulation, Nikki helps re-educate posture, decompress the spine, and release overworked muscles. The result: greater focus, less tension, and sustainable energy throughout your day.

  • Aging Spines and Joints – Restore Rhythm and Resilience

    Over time, gravity and repetitive strain compress joints and stiffen fascia, reducing mobility and vitality. Nikki’s regulation-first methods decompress the spine, re-educate posture, and restore fluidity through the fascial network. It’s never too late to move with ease, strength, and confidence again.

  • Biohackers – Optimize the System Before You Stack the Hacks

    True optimization starts with the body’s main operating system: the fascial and nervous systems. If fascia is dehydrated, restricted, or dysregulated, even the best supplements, cold plunges, peptides, or wearables can’t fully integrate at the cellular level. Nikki’s fascia-nervous-system approach restores conductivity, hydration, and regulation—so every hack, nutrient, and biofeedback protocol you use actually lands. When the matrix is healthy, your biohacks amplify rather than compensate.

  • Scoliosis – Realign from the Inside Out

    Scoliosis alters the body’s fascial tension and spinal communication. Using ELDOAs and fascia-based re-education, Nikki helps retrain alignment through the matrix, creating decompression and balance in the spine. With consistent practice, both children and adults can experience improved symmetry, stability, and comfort.

  • Pre- and Post-Surgical Patients – Regulate to Rebuild

    Surgery, injury, and inflammation can distort fascial tension and overload the nervous system. Nikki’s fascia-nervous system protocols accelerate recovery by restoring fluidity, decompressing joints, and reducing compensatory stress patterns. You’ll move beyond symptom management toward true, systemic healing.

Coaching with Nikki means real results and lasting change.

When your fascia and nervous system communicate in harmony, everything improves — from pain relief and posture to hormones, energy, and mood. You’ll receive all the tools you need to build your foundation for true, sustainable wellbeing.

My Happy Customers

Testimonials

  • Nikki fixes people. That’s what she does. Plain and simple. I showed up a broken athlete. I was strong in some areas but weak, imbalanced and in pain in others. In just a matter of only a few months, Nikki helped guide me through complete transformation both of my mind and my body. Now, not only am I a stronger and more balanced athlete physically, I am also a smarter athlete, having been armed with the knowledge to take my game to the next level.

  • Nikki is amazing! She is clearly very knowledgeable and a pleasure to work with. She is fantastic at assessing the body and asking questions to properly determine what my needs are. I appreciate her individualized approach and attention to detail. I can tell she is invested in my success. I’m so grateful to have found her!

    J. TostaStudent, Naropa University
  • Nikki is an incredible coach! I’ve worked with a lot of practitioners over the years and her knowledge, intuition, presence, and professionalism is the best I’ve encountered. I began seeing and feeling positive changes in my pain body, physical body, and psyche within a week after starting to work with Nikki. I appreciate her ability to tune into what’s really happening internally, meeting the client where they are, and pushing just the right amount!

    M. BurlingameSuper Mom and Entrepreneur
  • Nikki is always evolving her thinking. She pushes me, introduces new things and figures out the puzzle to keep me healthy and strong. I’m an intricate puzzle and she has figured out how to first make me work again, and now how to keep me working.

    B. SeamanCyclist and Entrepreneur
  • Nikki has been helping me with my low back issues. I have been making more progress with her combination of exercises and stretches than any other option I have tried. I have done PT, massage, Rolfing, a personal trainer, chiropractic, yoga, and stem cells, all of which helped some, but not as much as the progress I have had with Nikki.
