Holly Munger

Assistant Coach IVC Age-Group


My name is Holly Munger, and I am twenty-four years old. This will be my 7th season coaching for Marin Pirates Swimming. I have a broad range of experience working with all of the Age- Group swimmers. This upcoming season, I will be one of the primary coaches for our Captains group. I am also the age group drylands coach, where we stretch and do a lot of exercises to strengthen the core muscles along with agility work.
I am from the small town of Penngrove, California and grew up with the sport of swimming. Swimming has been a huge part of my life and has molded me into the person I am today. The sport of swimming provides kids with positive life long lessons, and I hope to carry those lessons to each of my swimmers. My swimming career started when I was just five years old. I have been with a couple local teams within my area (Sonoma County): Piranha Swimming, Twin Valley Aquatics, and Westside Aquaducks. Alongside with swimming with my club teams year around, I also swam for Petaluma High School. I was awarded “Most Inspirational” my Sophomore year and “Most Valuable Player” my Freshman, Junior, and Senior year. I graduated Petaluma High School in 2010, with High Honors and continued my education at Santa Rosa Junior College. I graduated from the SRJC in the fall of 2015 with Associate Degrees in Child Development, Early Childhood Education, and Social and Behavioral Sciences. I am currently at Sonoma State University entering into my Senior year as an Early Childhood Studies major. I plan on continuing my education further to obtain my Multiple-Subject teaching credential in the fall of next year.
I am excited to kick off the new season of 2016-2017, and I am looking forward to seeing our returning swimmers as well as meeting our new swimmers and families!

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!
