head-shotYgnacio Wood what time is it??? That’s right everyone, the summer of 2017 is upon us! My name is Conor Boal and this will be my third year returning to the decks of Ygnacio as a coach. I have been part of this team since the age of six when I first swam a race as a mighty seahorse. I also continued competitively swimming throughout my years at Ygnacio Valley High School.

I can’t wait to share my knowledge of this wonderful sport with you all and welcome you into the family of Ygnacio Wood! Goooooo Ygnacio!!!

Maggie Yamamoto – Co-Head Coach

Hey Seahorses! My name is Maggie Yamamoto and I am beyond excited to be joining Ygnacio Wood this summer! I grew up swimming for Valley Vista Swim Team for 13 years, Carondelet High School for one season, and I currently compete with the Walnut Creek Masters Swim Team. I was involved in the Cuda program and was a swimmer coach at Valley Vista Swim Team for a number of summers, I was an assistant coach at Valley Vista last summer, and I coached the YWST/VVST combined fall program. Swimming and coaching have been lifelong passions of mine. My philosophy focuses on proper stroke technique and racing hard while having lots of fun mixed in with everything. I am a graduate of Gonzaga University where I received a Bachelors of Science in Human Physiology and I will be attending University of Southern California in the fall where I will be pursuing a Doctorate degree in Physical Therapy. I am thrilled to be apart of such a magnetic team and I can’t wait for all the fun we will have together this summer!
