Meet Our Team

Sarah Derrenbacher, Founder & CEO

Sarah is a leadership and performance strategist who advises, consults, and works hand-in-hand with entrepreneurs, executives, and sports teams in the areas of peak performance, leadership, organizational/team culture, and mindset.

Her expertise is in guiding leaders and coaches through high-risk/high-reward growth and development, accelerating breakthrough moments, transforming mindset and culture, and sustaining peak performance. Sarah has built her expertise over 18 years of experience consulting with a wide range of businesses, from small and mid-size to Fortune 500, and with athletic directors, head coaches, and athletes across multiple sports teams and divisions in university athletics. Sarah has helped facilitate 20+ new individual and program records across clients, multiple league championship appearances, multiple first-time bids to NCAAs, a NCAA Sweet 16 appearance, and continues to touch the lives of the many athletes, coaches, and executives she works with. When Sarah’s not providing strategies to strengthen performance, she’s helping clients identify with and connect more deeply to the fulfillment and joy in what they do.

Sarah is the creator of the Evolveability™ Performance System. She is also a certified DISC behavioral analyst, a HeartMath Add Heart Facilitator, and a 10-year student of meditation and embodied inquiry practices.

I believe passionately that 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.

Isa Peczuh, Community Program Manager

Isa is an advocate for social-emotional learning for children in secondary schools. Her skills and passion around this type of learning within education and sports environments helps to deepen a child’s connection to athletics while also deepening their mental well-being and confidence. She aims to cultivate the potential in each child she works with and believes that social-emotional learning opportunities can lead to personal and academic growth for all children.

As a graduate from Vassar College with a Bachelor of Arts in Education and Psychology, Isa was also a member and two-year captain on the women’s basketball team. Under her leadership, the team set multiple program records, including a 16-game winning streak and an at-large bid into the NCAA tournament.

Isa is deeply connected to her purpose around creating a more equitable and holistic education system for students of all identities and backgrounds, and looks forward to sharing the Evolveability programming with younger athletes and community partners.
