Endurance Multisport started as two coaches combining their efforts to provide quality coaching across the three disciplines of triathlon. Over the years, we've added several associate coaches, and group of qualified instructors to help you meet all of your training needs!





head coach | director | owner

During the summer of 1992, in a small convenience store near the University of Pennsylvania where I was a student, I picked up an issue of Triathlete magazine. And I’ve been hooked on multisport ever since. I was drawn to the individual nature of the competition, the goal-oriented focus of the preparation, the variety and difficulty of the training, and eventually to the physical and mental challenge of long and ultra-distance racing. I set out on an exploration of personal limits. I became a student of the sport, absorbing all the information I could gather, all the while testing methodologies with my own training and racing. Years of advising fellow experienced athletes as well as easing new triathletes into the sport led me to discover a passion for teaching and a talent for coaching. Now, after all these years in endurance sports, I’m thrilled to be able to share knowledge and experience with the athletes I work with as a full-time professional coach.

triathlon coach

My triathlon journey started with a simple challenge to run the Broad Street Run in 2007 ... Wait, rewind 20 years ...  I had excelled as an athlete earlier in my life. I was Athlete of the Year my senior year in high school; having excelled in Golf, Baseball and Basketball. I remained relatively active throughout my years at college. After college,  I moved to the Philadelphia area to work for a small medical illustration firm.  Over the next decade, life became busy and I easily added on 5-6 lbs a year until I didn't recognize myself, so I started working out again. I was challenged to run the Broad Street Run. Ten miles may as well have been 100 miles back then, but I did it and it hurt and I loved it. Shortly after that someone floated the idea of doing a duathlon ... A what? ... So I bought a bike,  road it a few times and soon thereafter, completed my first sprint duathlon.  I thought I was going to die, but that was all it took. I was in ... hook, line and sinker, as they say. I was immediately drawn to the preparation and the technical nature of cycling, in general.  Over the course of the last 7 years I gradually challenged myself and have been challenged by the sport. From a Sprint to an Ironman, you find yourself out there. During the process of training and racing you are broken down and rebuilt ... and you continue on to the next challenge with a new sense of yourself.


My father was my coach throughout most of early athletic life. My earliest memories of athletics from childhood were out in front of our house after dinner.  My father practiced with me for months leading up to the local, regional and state finals for the Punt, Pass & Kick competition. He coached me in little league baseball all the way through to my senior year in high school on the varsity team.  He also supported me throughout my achievements in golf on the local and national level. My father had coached for many years prior as the high school girls basketball, volleyball and softball coach. He was a loved coach. He knew when to push and he knew when to listen. I had always thought that perhaps I would enjoy coaching and then the sport of triathlon came into my life. I really enjoy the technical and analytical aspect of the sport, but more than that, I enjoy the mental aspect of it. There is a fine line between thinking you can and knowing you can. When you find yourself out on the race course and you are confident in your training, the words of your coach and in your own ability ... well, that's when the magic happens.
