Hi my name is Katelyn Heinrich or "Kat". I played 4 years of collegiate softball as a pitcher, hitter and 1st baseman. I was an assistant coach at the college level as well, coaching at the NAIA and NCAA levels. I have attended many skills camps and trained with many college coaches. I specialize in pitching and hitting but also train catchers and infielders. My goal is to work with each athlete on an individual and group level to become the best player they can be.
Hi! My name is Octavia Bond, and I played 3.5 years of softball at Cal as an outfielder and slap hitter. I also coached for the NorCal Bears organization for 3 years for ages 13U, 14U, and 16U. During my time at Cal I coordinated multiple softball camps from ages 7-18, and loved working with each girl on their own personal strengths and weaknesses. While I was an outfielder and slap hitter in college, I played shortstop and was a power hitter as well growing up, being able to provide versatility to the field. I specialize in teaching outfield, slap hitting, and middle infield. While those may be what I specialize in, I am dedicated to help each and every girl become the best athlete they can possibly be regardless of their position on the field. In addition to this, I am a firm believer in helping my girls create success for the future off the field as well through the concept of life lessons taught by the game of softball (and baseball).
