Meet Our Team

Sarah Derrenbacher

Founder, Head Leadership & Performance Strategist

There is a different way of achieving high performance — a way that doesn’t leave us feeling depleted and fatigued from the pressure to perform and instead can heighten our ability to go and grow beyond our limitations, bringing deeper meaning to our lives and skillful mastery of our craft.

Inspired by the belief that the highest performance doesn’t come from a place of relentless struggle and strain, Sarah Derrenbacher founded Evolveability to guide leaders towards a more fulfilling way of achieving success within their team, organization, and society.

As an established Founder, trusted Leadership & Performance Strategist, and certified behavioral analyst, she is on a mission to re-envision the path to performance.

Since 2015, Evolveability has guided individuals and groups within sports and business to realize their potential and perform well beyond their expectations.

Over the past seven years, Sarah has contributed to over 20 league championships, NCAA tournament runs, and individual record-breakers in sports while helping Fortune 500 companies to outperform and growing small to mid-sized businesses into industry leaders.

From guiding teams out of slumps to accelerating breakthrough moments, Evolveability’s proprietary E3 Method™ successfully transforms groups through individual performance coaching and dynamic team sessions.

The first half of her 18+ year career focused on client success and partnerships, where she witnessed the direct correlation between performance and the wellness of individuals, groups, and environments. And Sarah has committed the second half of her career to transformation as she turns high-pressure environments into high-context cultures, fearful groups into motivated teams, and validation-seeking individuals into self-assured leaders.

With a background in Communications and Psychology, Sarah is an excellent communicator with a strong understanding of people. And as a 12-year student of meditation and Inquiry, her approach is enlivening and transcendent.

As an advisor for The Heartwork Institute, an organization that informed her own inner-work journey, a board member of the Rochester City Soccer League, and partner of like-minded organizations such as Rising Phoenix, Sarah finds fulfillment in helping others. By embracing awareness and humanness on our own journeys, she believes we can find unconditional joy within ourselves, our teams, and our world.

Working with Evolveability has taught me that we do not have to grind ourselves to the bone; that we can accomplish and achieve great things with compassion, empathy, and care.

Over the course of her 20-year career, she has successfully led the development and launch of multiple knowledge-based initiatives within global organizations in the employee engagement, employee recognition, and HR software space.  Her strategic and analytical approach and her passion for quality ensure efficiency and high-level client delivery.

Courtney gets excited by the impact and change when people start to see and make the shift from struggle into flow. She is grateful to be a part of a growing team that is dedicated to cultivating more fulfillment in work and in life. As a resident of Denver, CO, Courtney finds deep joy and rest in the mountains (pictured).

Our Philosophy

Our Philosophy

The highest performance doesn’t come from a place of relentless struggle and strain.

It comes from a place of wholeness and joy.

All our lives we’ve been told that high performance comes at a cost. And we’ve been warned that the cost is high. That it is about the grind, the hustle, the sacrifice; the fearless, relentless, single-minded pursuit of excellence. They said this was the only way.

They were wrong.

The real cost of high performance is care.

Make no mistake: Winning still takes grit. Stamina. And courage. It takes a lot of courage to care enough to win.

Caring this much requires vulnerability. It requires high tolerance for risk. It requires an environment where obstacles to success are identified, addressed, and shared openly and directly and without judgment. Where we have been given the permission and opportunity to be fully ourselves. Where it is safe to be fully present. Where it is safe to really, really care.

When the conditions are right, winning isn’t something you do … it’s something you are.

The highest performance, the most incredible achievements, and the realization of our fullest potential doesn’t come from a place of relentless struggle and strain. 

It comes from a place of wholeness and joy.

It comes from a place of perfect flow, where we are totally present and exquisitely aware. It arrives in the moment where the edge of our skill meets the threshold of challenge and our talent is fully actualized.

It’s not magic.

It’s proven. It’s a repeatable, reliable process. And it’s something we do again and again for coaches, executives, and teams who are ready to win.
