Coaching Philosophy

My main goals for the players that I coach are that they improve in the game of volleyball, build confidence, and gain strong communication skills.

CAP I – Certified

I have been involved in coaching sports since I was 14 years old when I was helping my dad coach my older sister’s softball team. I have always had the passion to be a coach and share my experience with others. I have been coaching volleyball for over 30 years. I have coached all levels and I have coached players from 8 to 60 years old.

I have had lots of successes in coaching and not all have come from winning a game. Just the idea that players finally get what I am asking them to do is the greatest gift I can receive. The player will look over towards me with a big smile, and we both know what has just happened.

I have my degree in Physical Education from California State University Long Beach. I’ve taken many things that I learned from my degree and incorporated them into my coaching.

I have always liked this quote that I share with all my teams. ”There is no limit to what can be accomplished if it doesn’t matter who gets the credit”

I started playing club volleyball with Diablo in 2008 and continued through 2013. I also played at Deer Valley High School from 2010–2013, earning BVAL First Team All-League honors and Team MVP my senior year. I then attended Sonoma State University, where I played four years of collegiate club volleyball while earning my degree in Computer Science. As the Women’s Club Volleyball President and Team Captain, I helped lead our team to the 2018 Division II NCVF National Championship.

I have remained very involved with Diablo, serving as Boys Program Coordinator and managing the club’s digital media, including its website and social media accounts. I have also coached both boys’ and girls’ teams at Diablo for over 9 years.

My goal as a coach is to help players develop their volleyball skills and understanding of the game to their fullest potential in a fun and positive environment. Coaching has been an incredibly rewarding experience, and I’m excited to continue helping players grow, reach their goals, and discover their love for the game, just as I have!
