Ryan Garcia Varsity Coach

Ryan Garcia is born and raised in San Jose. As an age group swimmer, Ryan was a Pacific Record holder and placed high at meets, including Far Westerns, and all the way up to Junior Nationals.  Living in the Bay Area, he competed for club programs such as Santa Clara Swim Club, West Coast Aquatics, and our own club, Palo Alto Stanford Aquatics.  Ryan attended Bellarmine College Prep high school, where he was a four year All-American and helped to lead his team to four straight CCS team titles.  He then moved to attend UC Santa Barbara, where he competed for the Gauchos and was All-Conference during his time there.  Ryan continues to compete at Master’s competitions and won backstroke titles nationally in his age group.

“My focus is on the development of the swimmer as a whole. I want them to learn the fundamentals of swimming and gain the necessary mindset to be successful in this sport. I want them to learn and gain important characteristics, such as developing a hard work ethic and being accountable. I want to create a challenging as well as rewarding environment for the athletes and create a love for the sport. Whether it be recreational or going to the next level of competitiveness, my goal is to foster a foundation of support for these swimmers.”

Keiichiro Yoshida Age Group & Advanced Age Group Coach
Keiichiro, "Coach K," begins his second professional start in coaching at PASA Rinconada beginning in the Fall 2019, primarily working with swimmers ages 10-12 years.  He has been coaching for more than 20 years, receiving his first professional start in USA Masters Swimming, coaching over 100 swimmers in a single practice, ages 18-87 years.  After a few years working in his field, he began Age Group coaching in 1996, and received his first full-time position in 1997.  He has coached all levels throughout his career including Senior student-athletes. Coach K has also held coaching and administration positions at the NCAA Division 2 and NCAA Division 1 levels, in both Men's and Women's Swimming and Diving Programs.  
Coach K swam competitively as a walk-on student-athlete at the University of Maryland, and has been mentored by some of the greatest coaches in the sport today.  Prior to his arrival at PASA Rinconada, he spent time volunteering for USA Swimming while transitioning his coaching from youth student-athletes to working with executive leadership and entrepreneurs.  He maintains two mantras while working with individuals of all backgrounds - the first he received from his coach mentor:  "No one cares how much you know until they know how much you care."  The second is a quote that he discovered while attending the USA Swimming Coaches College at the US Olympic Training Center, and is a quote that he tries to consistently model and instill into all of his student-athletes on a daily basis:  "Success is a Journey, Not a Destination."  
"Coach K" is an active member of several local boards, and enjoys supporting fellow coaches in a variety of sports as a trainer for the Positive Coaching Alliance.  He is the proud father of two children, and a dog named Kekoa.
Tisha Steimle Head AG Coach - Killer Whales & Sharks

Tisha was born and raised in San Jose and swam for San Jose Aquatics, one of two teams her Dad started. She began coaching in high school as an 8 and under assistant for her summer league team.  She took her first paid coaching job in 1980 and has been active in coaching swimming ever since. Graduating from Lewis and Clark College in Oregon, she stayed in Oregon for three years coaching Oregon City Swim Club.  Desiring a return to the Bay Area, she took the Head Age Group position at Palo Alto Swim Club in 1988.  With exception of a rewarding year spent coaching at Bradford-on-Avon Swimming in England, she has been at Rinconada ever since.  Returning from England, she took over the 9-10 year old age groups in 2004.

"Teaching kids to improve their strokes, watching their confidence grow and their ability to handle new situations that get thrown at them, is what I love most about coaching.  Watching a child "get it" is what keeps me coming to the pool day after day."

During her PASC/PASA years she has coached Nationally ranked swimmers in 9-10, 11-12, and 13-14 age groups.  She has coached Pacific Swimming Swimmers of the Year, Pacific Swimming Record Holders and many athletes who have made Western Zone and Pacific Swimming All Stars.  She has served on the Pacific Swimming Board of Directors and the Age Group Committee. Tisha has been nominated 3 times for Age group Coach of the year for Pacific Swimming.

Tisha and Tony love to travel the world and have done so with many swimming connections, and Tisha loves to take photos of her travels to make it seem like majoring in Art in college was worth all the money!  Tisha loves reading, Pittsburgh Steelers, San Jose Sharks and the Olympics.  She loves Presidents' and Ryder Cup golf and Professional Cycling.

Her experience from all over the Bay Area includes Ladera Oaks, BAC, Alameda Islanders, Golden State Water Polo/Swim, Aquatics Director at the Palo Alto JCC, & Skip Kenney's Nike Swim Camps before joining PASA 10 years ago. Hilary has coached dozens of swimmers to Pacific Swimming Zone Championships, Zone All-Stars, Junior Olympics, Far Westerns, CCS, and US Olympic Trials. Siince taking on the 8U Coaching position at Rinconada, she has had 100% success improving swimmer's times in every race. 

When not on the pool deck, Hilary stays busy with her other profession—Emergency Medical Response.  As a Paramedic, she is heavily involved in developing & teaching Aquatic Safety & Rescue protocol, teaching Search & Rescue techniques, and instructing CPR, Advanced Cardiac Life Support, Basic Life Support, First Aid, & Wilderness Medicine. To date, she has had thirteen personal saves in the field.

She teaches boating safety courses through the US Coast Guard Power Squadrons & currently ranks in the Top 10 Female shooters worldwide.

Coach Hilary believes her success with PASA’s 8U program can be directly attributed to the Coaches with whom she’s fortunate to work; “to be able to shape these young kids from novice level to national competitors as they matriculate through our program…wouldn’t be possible without the wealth of experience, the vested interest & vision that the Rinconada Coaches have—it’s truly invaluable.”
