Focused training to unlock your full potential.

As a coach, my mission is to empower athletes at every level to realize their full potential by drawing on the lessons and experiences I've gained over the years. Success comes not just from the training plan itself—but from the strong, communicative partnership between coach and athlete. I believe that regular feedback and honest dialogue transform a standard plan into a tailored strategy that fits the athlete’s goals, experience, and lifestyle. When communication is open, implementation becomes seamless, and the athlete’s path forward is clear.

With over two decades of experience in endurance sports, I've developed deep expertise across all facets of athletic training—from nutrition and strength conditioning to race strategy, equipment, and scheduling. My coaching philosophy is rooted in both study and mentorship, shaped by real-world experience and a passion for helping athletes grow.

I hold certifications from USAT Level 1, Ironman University, TrainingPeaks Level 2, 80/20 Certified Coach and US Masters, equipping me with the knowledge to guide athletes of all levels. As head coach of a YMCA program with over 50 members for five years, I supported athletes training for everything from 5Ks to Ironman triathlons.

Now through Gu3 Training, I work with athletes across the United States, creating customized programs for triathlon and running. I've helped dozens achieve their first finish lines—and others reach elite milestones, including IM 70.3 World Championship and Kona qualifications.

My approach to balancing training with all the aspects of day-to-day life will take the guesswork out of the process
