Coaches and Staff Bios

Robyn Ross

Robyn has a strong background in gymnastics as an athlete and wanted to “Pass it Forward” and became a coach at a YMCA in South Pasadena. She coached through her college years and when she had children, her oldest JJ Ross was introduced to the sport of gymnastics at a young age and started the whole ball of wax all over again! He never looked back. He competed from age 7 to 18 and started coaching at the age of 16. At age 21, JJ and Robyn opened their own club, Champion Gymnastics & Cheer together in June 2008. We started with 30 athletes and have grown by leaps and bounds. My goal is to motivate and inspire each athlete by instilling strong values and self-respect and to show them how to strive for even more. Teaching our coaches to “Lead by Example” and treat each athlete as if they were their own. The moment you walk through our doors you will see and feel what CGC is known for….FAMILY!

JJ has been in the gymnastics world since age 7. He competed for 12 years throughout the Junior Olympic Qualifiers and Regional Invitationals. JJ's heart was in love with the sport as well as coaching it. He knows the hard work and countless attempts to achieve the skills in this sport. To be able to share that with others, is something that he has wanted for a long time.  JJ coaches just about everything. Currently, JJ is the Head Coach for our Level 4 to Elite Boys Compulsory/Optionals Competitive Team. If it has to do with gymnastics....JJ coaches it!

Savannah Ross

My name is Savannah Ross and I have been involved in the sport of gymnastics for about 20 years. I started doing gymnastics at the age of 6 and competed through the age of 18. I began coaching at 18 and have had the chance to work with such amazing athletes ever since. I love being able to coach these gymnasts through their struggles, provide them with a confidence that they didn't even know they had, and watch them grow not only as an athlete but as a person in general. I love to watch the joy spread across their face as they achieve new skills or move up into the next level. Gymnastics has been such a positive thing in my life and I want to share that with everyone that I get the pleasure of working with.

Amy Ferraris

Gymnastics has been in my life for over 20 years. I participated in the sport from age 7-18, competing in the Junior Olympic Program, qualifying for multiple state and regional competitions up to level 9. I also competed in Track & Field as a sprinter and jumper. After high school I began Weightlifting and earned a spot on the US National Weightlifting team and won multiple national championship titles while competing professionally for 8 years. I attended Western Oregon University where I earned my Bachelor’s degree in Exercise & Sports Science with a minor in Spanish. During my undergrad I worked as an intern with the Oregon State Gymnastics Team and helped to develop their strength and conditioning program. After graduating I continued coaching Gymnastics at a club in Oregon where I coached levels 3-10 and multiple level 9 regional and national champions. I coach gymnastics because I love the sport, but also because I want to make sure that every one of my athletes is given an experience that is positive, supportive, safe, empowering, and meaningful. My personal coaching mantra is, “If they have not learned, you have not taught” and I believe that every child deserves my very best effort as their coach. I am so honored and humbled to be a part of each of my athletes’ gymnastics experiences. 

Andrea Chance

My name is Andrea Chance, and I am one vocal (some would say loud), positive, and high energy coach that loves the sport of gymnastics. Gymnastics is my passion, and getting to share my passion is truly a gift. I have been involved in the sport of gymnastics for over 20 years. I studied business and marketing at Lewis Clark State College in Idaho. I started as a gymnast at the age of two and soon went on to compete at an optional level in the state of Montana. I was a competitive dancer, and trained in ballet, jazz, and tap. I have been coaching gymnastics for over 13 years. I have coached all levels from just walking to optional level competitive gymnasts. I have been USAG certified the entire duration of my coaching career as well as attended National Congresses and completed USAG courses and training. The best part of coaching for me is seeing a child's face light up when they achieve something that they have worked so hard for! My goal is to help every child achieve confidence, discipline, overcome obstacles, teamwork, and above all else have fun!

Brittany Pharis

My name is Brittany Pharis and I have a huge background in Gymnastics, Dance, and Competitive Cheerleading. My gymnastics career started at the age of three and lasted for the next 12 years. I have been coaching competitive USAG compulsory teams for ten years, as well as, judging high school gymnastics for NFHS for the past nine years. I have just recently begun my adventure into the Judging world of USAG and cannot wait to see what opportunities are to come. I have been a dancer all my life competing, showcasing and participating in semi-pro and professional dance teamsDance along with gymnastics are one of those sports where it can change your life for the better. I possess three bachelor’s degrees in Dance and Choreography, American Sign Language, and Criminal Justice and Criminology. I am currently obtaining my Single-Subject teaching credential and Master’s in Education. I want to teach our athletes not only the art of gymnastics and dance but life lessons along with learning to be a better human being then they were yesterday. I want them to understand that with hard work, motivation, and dedication they can do anything their hearts desire.

Brynnan Venters

Hi Everyone! My name is Brynnan. I have been doing gymnastics since I was two years old. I started competing when I was 11 years old and I haven't stopped. I am currently a college student, participating in club gymnastics at San Jose State. I love coaching the sport of gymnastics. I started coaching 3 years ago. I love watching the look on a kids face when they get a new skill or land something they have been working really hard on. This sport has had such a huge impact on my life and I hope to help other kids love it as much as I do.

Sherri McCullen

Sherri’s love of gymnastics began when she was an elite gymnast way back in the 80’s (before

most of the coaches at CGC were born!). Since then she has been a coach, choreographer, gym

owner, judge, Ironman finisher, world traveler, CrossFit competitor, and mom! Sherri always

has a positive attitude and teaches her gymnasts life skills as well as gymnastics skills: be kind,

be healthy, and always give 100% effort!

Diego Mercado

I was a gymnast for 21 years. I got to compete for Mexico’s Senior National Team and the University of Iowa, and I have now been coaching for 10 years. I like the fact that gymnastics is a very unique sport. Not everybody can do it at the highest level. My goal for my athletes is to make sure they are having fun, while working hard to be the best.

I also assist with Birthday Parties, insuring that all kiddos have a great time. I am thankful for all that Champion and Coach JJ has given me and I am looking forward to meeting my goal as a gymnast to go to the Olympics.

Austin Adams

What’s up, my name is Austin Adams I’m the tumbling, boys gymnastics, and parkour coach! I grew up in Austin, Texas where i spent most of the time playing sports like football, wrestling, track and lacrosse, and I work all through high school as a rec gymnastics, and as tumbling coach and then started practicing and teaching parkour my senior year. There is nothing I love more in this world then watching people accomplish their goals, and I get to be lucky enough to have a part in helping them here at Champion. 

Hey, athletes! My name is Justy Rice, and I am one of the instructors for CGC's Tumbling classes! A little bit about me: I have been -- for 13+ years -- a gymnast/tumbler, certified Taekwondo Black Belt, as well as a Master Class level dancer, thus exposing me to a variety of sports. As a takeaway from those activities, I believe that the basics are a crucial part of growth as an athlete for any sport, and therefore my tumbling class will always focus mainly on developing the students' understanding of important tumbling fundamentals. This solidity of technique allows for more success when eventually moving on to more advanced level tumbling classes; something I'd like to see in all of my students. My goal is that when you take my class, I can effectively spread the knowledge I've gained over the years, as well as evolve your skills so that over time you can be the best tumbler that you can be. That being said, always remember to keep working your hardest, and I hope to see you in class!
