My swimming career started in Arcata with Humboldt Swim Team at the ripe age of nine, and I continued swimming through high school. During the 2003 and 2004 high school swim season I was Eureka High Swim Team's MVP.  After graduating high school in 2005, I was the head coach for Redwood Swim Club for three years. During this time, I finished my general education at College of the Redwoods. I moved to Santa Rosa in 2008 not only to coach for the Santa Rosa Neptunes but to pursue my Bachelor's degree at Sonoma State University.  I was an assistant coach for Neptune Swimming for three years while also serving as the Head Guard for the Santa Rosa City Park and Recreation Department.  In 2011, I obtained my B.A. in Criminal Justice and Criminology, and recently started my masters program for coaching and athletic administration. I have a great passion for coaching and developing swimmers and have a well-rounded background working with all types of children, from at-risk youth to elite level swimmers.  I am enthusiastic to build the Pirate swimming community, and as a coach I hope to give back to my swimmers what this sport has given to me.

This will be my 6th season coaching with Marin Pirates Swimming. I have experience working with our Age-Group program, primarily with the 8 and under and the 9-10 year old groups. This year I will also be working with the 11-12 group as the primary drylands instructor, alongside with Andrew Johnson. I am from Penngrove, California and grew up with the sport of swimming. Swimming has been a huge part of my life and has molded me into who I am today. Swimming provides children with life long lessons and I hope to make an impact on every one of my swimmers as my coaches has done for me. My swimming career started when I was 5 years old. I have been with a couple local teams within my area: Piranha Swimming, Twin Valley Aquatics, and Westside Aquaducks. Alongside with swimming with my club teams I also swam for Petaluma High School. I was awarded “Most inspirational” my Sophomore year and “Most Valuable Player” my Freshman and Senior year. I graduated Petaluma High School with High Honors in 2010 and continued my education at Santa Rosa Junior College.

Griff Helfrich

Senior Team Dryland Coach


I was born and raised in Williamsburg, Virginia, where I started swimming and playing other sports at an early age. Competitive swimming helped me earn a scholarship to swim in college at the University of North Carolina, where I specialized in the 200 butterfly before a shoulder injury forced me to retire from competing after 3 years. I earned my degree in Philosophy in 2005 and have been coaching swimming at every level and every age group since then. In 2011, I started training at CrossFit gym and have since gone on to compete at CrossFit and become a Level 1 Certified CrossFit coach and am currently employed at Tamalpais CrossFit. Living in California is the fulfillment of a lifelong dream for me and I am extremely excited to become a part of the Marin Pirate family and share my wisdom, passion and experience with everyone!
