Our Peak VO2 Team | Meet the Owner
Bree Mabley, ACSM Certified Clinical Exercise Physiologist (CEP) with BLS and ACLS certifications, brings 16 years of hands-on experience from world-renowned cardiology hospitals to her mobile service, PeakVO2. A Colorado native raised in a small mountain town, Bree developed a lifelong passion for outdoor adventure and athletics, earning a collegiate softball scholarship at Hastings College while graduating with dual degrees in Exercise Science/Kinesiology and Psychology. These foundations led her to a cardiology clinic early in her career, where she discovered her calling in exercise physiology.
For over a decade and a half, Bree performed cardiac and cardiopulmonary stress tests of all kinds, working side-by-side with top physicians and providers in high-stakes diagnostic settings. This clinical expertise honed her ability to interpret complex physiological data—from VO2 max thresholds to resting metabolic rates (RMR)—and communicate it clearly to support patient outcomes, rehabilitation protocols, and performance training.
Now through PeakVO2, Bree offers fully mobile VO2 max and RMR testing tailored for clinics, hospitals, gyms, and health clubs. Services include precise submaximal and maximal assessments, detailed reports with zone training recommendations, and actionable insights for nutrition, endurance building, and recovery. Whether supporting post-rehab clients, optimizing athletic members, or empowering everyday fitness enthusiasts, PeakVO2 bridges the gap between lab precision and real-world application, helping your team deliver personalized, evidence-based results that drive progress and client satisfaction.
Bree founded PeakVO2 to bridge the gap between well healthcare and performance; to deliver hospital-grade metabolic testing to improve overall health, wellness and to promote longevity.
