Meet the Team
Erin Renzas
Erin is a former tech executive and operating partner who has worked across more than 80 global companies at the intersection of leadership, growth and transformation. Boxing became a catalyst for rethinking her own relationship to work, identity and ambition — and ultimately the foundation for Fight Co.Lab. Today, she is an entrepreneur, advisor and author developing a memoir with Simon & Schuster on boxing, burnout and the fight for something entirely your own.
Christina Lang
Christina is a senior marketing and brand leader with deep experience building teams, shaping strategy and leading through organizational complexity. After participating in the first Fight Co.Lab, she became part of the team behind it. Today, she oversees operations, bringing the same strategic rigor and instinct for turning ideas into action that has defined her career.
Shea O’Neil
Shea is an executive coach and facilitator with more than two decades of experience helping leaders navigate complexity, change and growth. Her work brings together executive coaching, somatic practice, neuroscience and personal mastery to help people develop greater clarity, presence and capacity under pressure. She co-developed the Fight Co.Lab experience and leads its facilitation.
Fight Co.Lab is shaped by coaches whose expertise goes beyond the ring — bringing together elite boxing experience with a deep understanding of presence, composure, clarity and strategy.
