The “Why” Behind The Work

For over 15 years, I navigated the niche world of performing arts PR and marketing. But behind-the-scenes, I was managing a much more personal challenge: birthing injuries—including diastasis recti and multiple hernias—that fundamentally changed my relationship with my body.

I spent four years exhausted by every physical therapy protocol and non-surgical option available before advocating for the surgery I needed to truly heal. I wasn’t a runner then; my recovery required starting from zero. I began with simple, intentional walking, eventually pushing into high-intensity power walking to test my core’s stability. Those power walking intervals became jogging intervals, which later became running intervals, and ultimately snowballed into adjacent strength training.

Later, while researching exercise science to understand why my intuitive recovery was so effective, I discovered my method closely aligned with the principles of Japanese Interval Walking. I also realized that my commitment to consistency played a major role in my results. That is exactly why I called my business iwill. It’s not “I’ll try,” and it’s not “I can”—it’s a commitment to showing up. It’s not about perfection; it’s about the fact that you will show up for yourself and live with purpose. Today, I combine that lived experience with these evidence-based frameworks to help others navigate their own physical “pivots” and safely acclimate to higher-intensity movement.

My Approach: Longevity in Motion

While I am now an avid runner, my coaching is built on “fitness for life.” I focus on helping people who feel sidelined or hesitant about getting back into motion. My goal is to help you rebuild your foundation so you can transition into higher-intensity exercise with confidence.

My Approach Focuses On:

The Power of the Interval: My methodology is inspired by Japanese Interval Walking (IWT), a high-impact tool for building a powerful aerobic foundation. For those starting from the ground up, we adapt these principles to create the perfect “bridge” to movement. For runners, we apply these same interval structures to your sport—using toggled intensity to increase speed and stamina without the burnout.

Smart Acclimation: I provide the structured roadmap needed to get your body used to working hard again. For non-runners, this is your on-ramp to movement; for athletes, this is the active recovery and base-building required to increase your tolerance for exercise without the ‘all-or-nothing’ burnout.

Consistency & Fuel: Progress happens when you show up regularly and support your body with evidence-based nutrition. I help you manage both so you have the energy to live your most capable, inspired life.

Senior Fitness & Longevity: I apply strategies designed to keep you mobile, independent, and vibrant. My focus on longevity ensures that whether you’re chasing a personal best or a grandchild, your body has the resilience to keep up.

The Scene Room Podcast

Additionally, I host the podcast The Scene Room. While it began with a focus on the business of the performing arts, I am shifting the conversation to align with my new career pivot while remaining connected to my roots.

I explore wellness in conjunction with cultural experience and the importance of music in our communities—from the benefits of music therapy on the brain to its role in early childhood development. I am obsessed with the rituals and mindsets that sustain us; I believe that while fitness supports our ability to be creative, it is ultimately the foundation that allows us to show up for our work and our lives with resilience.
