Assistant Head Coach - Georgi Cappelletti 

Georgi Cappelletti has been with the HOX for 25 years; 14 as a swimmer and this will be her 11th year as a coach. Her accomplishments in the water include breaking multiple records: the HOX 13-14 50 breast team record, in addition to the 15-18 100 free record at County, Woodlands and VSA League Championships, which held for several years. She is still the current HOX team record holder in the 100 free.  Coach Georgi attended Monte Vista High School in Alamo and was a member of both the Varsity Swim Team and the Varsity Water Polo Team. During her senior year of high school, Georgi’s 200 free relay broke the meet record at NCS.  She went on to play Division 1 Water Polo for two years at University of California, Berkeley and graduated in 2011.

She loved growing up on the Blackhawk pool deck because of the fond memories created, life-long friendships formed, and personal goals achieved. It is her desire to create that same experience for every HOX swimmer she coaches. Georgi brings a tremendous level of dedication and spirit to the team and leads the Hike to Hawk during Spirit Week each summer. She loves coaching kids of all ages, but her specialty is leading the 10 and Unders and instilling a foundation for a long-term commitment to swim and love for the team. She completed her teaching credential in December 2013 and has worked at Tassajara Hills Elementary School since 2014.

Assistant Coach - Michelle McConnell

 I am very excited to be a part of the HOX Coaching Staff, coaching the 8 and under age groups as well as the mini HOX this season at Blackhawk.  I grew up in Concord, and graduated from Ygnacio Valley High School.  In high school I played waterpolo, basketball, and was a member of the swim team.  I was the first athlete in the history of my high school to receive 12 varsity letters for the sports in which I played, and in 2015 was inducted into the Ygnacio Valley High School Athletic Hall of Fame. Upon graduating high school I attended Brigham Young University where I received my Bachelor of Science Degree in Physical Education Teaching, Kindergarten through 12th grade and a minor in Spanish. I returned to Ygnacio Valley High School to teach Physical Education for two years before returning to school to receive my Masters of Arts Degree in Education, with an emphasis in Athletes and Academic Achievement from the University of California, Berkeley. This is my 12th year teaching in the San Ramon Valley School District. I taught Physical Education, and was the Assistant Athletic Director at Monte Vista High School two years before coming to teach Elementary PE at Creekside.  I have over fifteen years of swim coaching experience coaching at Ygnacio Wood Swim Team, Valley Vista Swim Team and Roundhill Swim Team.  I love the sport, and hope to help my swimmers have the same passion for it that I do.  

I am married to Jason McConnell, and we have a 10 year old daughter named Mia, and 4 year old son William.  I am looking forward to a great summer at Blackhawk.  Go HOX!
