Coaching Staff


Marie McSweeney, Head Coach

Coach Marie McSweeney

Marie McSweeney is Head Coach of the Tidalwaves Swim Team as well as the Head Coach of Tam Masters, an adult swim team recognized for its excellence in the US. Marie has developed Tidalwaves into a foundational swim and athletic experience for thousands of children in our community -- in fact, many of our team's current parents fondly remember being coached by Marie when they were young! 

Marie has the ability to encourage, motivate, and support swimmers, young and old, in a POSITIVE way that focuses on transferring her love of the sport to her swimmers. On top of that, she has an unbelievable memory for names and swim times. You, too, will marvel at the way she can tell them all apart even when they are all wet! This will be Marie's 30ish year with Tidalwaves. 

Have a coaching question or concern about your child?

Coach Marie is always open to talking to you. However, during practice and meets Marie needs to be focused on ALL the kids in the water. This is for safety reasons as well as to ensure all swimmers get the most out of their practice and meet experience. The best way to let Marie know you have a coaching question or concern is via:

Lisa Wulf, Assistant Coach

Lisa Wulf is back this year for her third Tidalwaves swim Season. Lisa started swimming competitively at the age of 8 for the Orinda Aquatics in the East Bay. She continued her competitive swimming career until college when she decided to pursue basketball. During her years of competitive swimming, Lisa began coaching as an assistant coach for the Sycamore Stingrays, a summer league swim team in Danville, CA.  While attending the University of South Carolina, she continued coaching at the club level for the Carolina Aquatics Swim Team.

Lisa moved out to San Francisco after college and met up with Coach Marie to coach for the Marin Pirates. We knew she would fit right in with our Totally Tubular Tidalwaves Coaching Crew!  Even though Lisa works full time as a Customer Enablement Manager she absolutely loves working with kids and giving back to the community by coaching a sport she is extremely passionate about. We feel very fortunate to have her with us again this season.

Leena Bing, Assistant Coach

Leena Bing was born and raised in Oregon and is the oldest of 4 siblings. Her mother was an aquatics director for a small local pool so she grew up on the pool deck, spending summers in the water. As a teenager she spent many years lifeguarding, teaching swimming lessons, and later joining the local USA club team in order to stay in shape for basketball. Leena went on to coach the Novice program for that team. Her other coaching experience includes serving as an assistant coach to a couple of summer rec programs in the East Bay: the Blackhawk Country Club, and the Danville Sea Devils. Leena is very excited to bring her high energy and love of coaching to the Tidalwaves.

Matt Whittle, Assistant Coach

Matt Whittle joins us for his second year as a Tidalwaves coach! Matt recently completed a degree at UC Berkeley where he was captain of the Men's Swim Team. Matt's interest in pursuing swimming seriously started in high school, after a youth dedicated to multi-sport exploration and enjoyment.  His swim times?  How about a 1:46 200 yard IM, and 53.0 100 yard breast stroke? Not bad, Matt, not bad.

Matt's coaching experience includes coaching the Davis Summerdarts summer league team near his home town of Davis, coaching private lessons, and working as the Head Counselor at Cal Berkeley swim camp. Matt, we welcome you to our Tidalwaves community. (Go Bears!)

Scott Sherrod, Assistant Coach

Scott Sherrod feels like he literally grew up in the water. After taking swim lessons at a very young age and subsequent adventures in boating, waterskiing, and wakeboarding, Scott started swimming competitively in high school. He then continued competing at Santa Rosa Junior College, where he also played water polo and became a professional scuba dive master.

When Scott’s not on deck passing on his love of the water to our Tidalwaves, you can find him working at the Marin Dive Center, where he teaches people of all ages how to safely scuba dive in open water. He continues to swim 5 days a week.

Alex Sennhenn, Assistant Coach

Alex Sennhenn started competitive swimming three years ago when he swam for Warren Lager on the College of Marin team. After two successful seasons swimming for Warren, Alex transitioned to US Masters, where he currently competes with the Tamalpais Aquatic Masters (under Coach Marie!).

Sierra Kim, Assistant Coach

Sierra was born in Daily City, CA and moved to Novato at the age of two. She began swimming competitively when she was 9 for the Marinwood Waterdevils, where freestyle and breastroke were her two top strokes. Her family believed she was meant to be a mermaid or some sort of fish since she spent so much of her childhood in the water! 

After graduating from the Novato High School Marin School of the Arts, Sierra began teaching swimmers of all ages at the Kings Swim Academy. After attending the dance program at the College of San Mateo, Sierra transferred to Santa Rosa Junior College where she's now part of their animal science program.

Sierra is very excited to be starting a new chapter with the Tidalwaves. She has a huge heart, is very humorous, and loves working with kids.
