I’m a USAT Level 1 coach and since 2011 I’ve coached athletes to pro card qual, Kona, Norseman (black shirt), 70.3 Worlds, ITU Long Course Worlds (Tri & Du), USAT AG Nats (Tri & Du), State TT podiums and numerous Boston quals.

Most of my athletes race long course events (70.3, 140.6, ultra/full/half marathons) which is my area of specialty, but I work with talented, short course athletes also.

I’m a 12x Ironman, 5x Kona qualifier (2013-15,2017, 2020), 5x 70.3 Worlds qualifier (2011, 2013, 2016, 2017) and 9x USAT All American (2010-2018). In 2013 I was the WTC #1 ranked Ironman (M40-44) in the US and #3 Worldwide. In 2016, I set the course record (at the time) for my AG at IM Cozumel.

I limit myself to a handful of athletes who are focused, motivated and committed to progress and who bring positive energy to the table. I'm a big proponent of knowledge transfer, execution and making sure my athletes are progressing in a balanced environment so they can maintain sustainability in the sport.

In 2011, I co-founded Meridian Performance with my wife, Jennifer, who is also a USAT coach. While we each coach our specific athletes, each of our athletes benefits from our collective experience, input and attention.
