Meet our Amazing Virtual Coaches


Sami Czarnecki - Tennis Coach

I am originally from Sioux Falls, South Dakota. I have been playing tennis since I was about 6 years old and have always had a love for the game. My Senior year of High School I was awarded "Most Winningest Player" in South Dakota, and am currently at Rockhurst University in Kansas City on a tennis scholarship.   

Besides my love for tennis, I also have a love for teaching kids. After graduating Rockhurst this spring I will become an Elementary Education teacher. I am very excited to teach young athletes who also share a passion for tennis. My motto is that there is always room to grow and improve in your abilities on and off the tennis court. 

Adrielle Morante - Basketball & Tennis Coach [Bilingual English/Tagalog]

I have worked with Kassirer Sports & Youth League tennis for 8 years.  I grew up playing youth & high school athletics in San Francisco, Bay Area, California & I was awarded “Most Inspirational Player” by my coach Raymond Wong, as an athlete for leadership. My mission is to serve the community and youth to challenge themselves to become the best version of themselves by focusing on mastering fundamental movement skills. 

I attended Skyline College to obtain an associate’s degree in allied health science. While going to school, I developed a passion for working in the health & fitness industry. I worked at Sports Club/ LA San Francisco, and transitioned over Equinox Sports Club as a Sports Manager. I want to pass on to my students that you can grow through the adversity you face playing sports,  “It strengthens competitiveness, personal and professional values, self-assessment, teamwork, leadership, empathy, and emotional control. Through sports, I believe that it can help navigate relationships with others, and with ourselves as well as how to understand how our emotions can change the way you live and love.”   In my spare time, Adrielle loves to spend his time being active through basketball, cycling,  weightlifting, and adventures with his super dog, Biggins. I hope my students are able to grasp the concept of how to associate E.I. and reflective practice with applied sports or fitness performance.  My primary goal is to develop a positive inviting environment for students to grow.

Michael Hsu - Basketball Coach [Bilingual English/Mandarin]

My coaching career began in 2005 with Beijing Aoshen Olympians. It was a professional team from China that developed many players to play for the national team. We even developed a player named Sun Yue to make it to the NBA. I worked for them for 6 years as the assistant coach and skills trainer. During the period, I was very fortunate to learn from many great coaches like Phil Jackson (NBA's most championship winning coach), Pete Carril (former Sacramento King's assistant coach, famous for his Princeton Offense), Paul Coughter (FIBA Coach of the Year in 2006, legendary coach in Asia), Bill Tosheff (first NBA Rookie of the Year award winner, Indiana University Basketball Hall of Famer), Mike McGee (won 2 NBA championships with the Lakers in 1982 and 1985), etc. 

During the years from 2006 to 2010, I was also the basketball trainer of Sun Yue and Songtao Zhang. Both are Chinese National team players. Sun Yue was playing for Los Angeles Lakers from 2008-2009, and later on with New York Knicks and Washington Wizards. I was able to attend and observe all of their practices, trainings, meetings, and games during the time he was with those NBA teams.

From 2011 to 2015, I was running my own basketball agency/academy based in Covina, California. Other than representing players and coaches, we also did a lot of player skill development and camps for college and pro players, as well as youth athletes. We had done many basketball exposure tours to participate in many international exhibition games and tournaments in the countries like Mexico, Philippines, Japan, Taiwan, Indonesia, and China, as well as hosting basketball clinics in those countries. 

I’ve been continually coaching basketball and training players after I settled down in Pleasanton since 2016. Other than the local AAU teams I've been coaching, I have also started to coach basketball with Kassirer Sports since 2018.
