Our Founders
Valerie Penn — Founder
Valerie Penn is the founder of Calibrate and a Peak Pilates® Level III instructor, certified across the full apparatus in the comprehensive classical system. She discovered Pilates in 2000 under a teacher trained and certified directly by Romana Kryzanowska — Joseph Pilates' own protégée — and has been devoted to the method ever since. After losing her husband, Valerie stepped away from a senior executive career in business and returned to the practice that had anchored her through the hardest season of her life. That experience shapes everything at Calibrate: her focus never changes — helping each client move with confidence and reach their goals, within a community where it is safe to show up exactly as you are.

With over 35 years in movement and fitness, she owns and operates one of the Dallas region's premier classical Pilates studios.
