Staci lifshen

I was born & raised in Dallas then graduated from the University of Arizona with a degree in Elementary Education. After graduation, I chose Denver to be my new home. Shortly after arriving, I discovered JumpBunch & became a Coach in 2007. Then, in the fall of 2010, I purchased the franchise and decided to continue expanding the business to include TGA in 2022. I have always had a strong passion for sports and grew up being a competitive gymnast while somehow also finding time for dance, basketball, soccer & softball. Now, even as an adult, I stay active through yoga, pickleball & volleyball. I also enjoy escaping to the beautiful mountains of Colorado to hike & camp with my wonderful fiancé, Steven and our sweet German Shepherd mix, Indiana Bones.

Steven Stockdale

Raised in Savannah, GA, I have been blessed with parents, coaches, and mentors that instilled a love of athletics from a young age. My parents instructed ballroom dance, and my first introduction to competition was as a young child in ballroom dance. I began studying and competing in TaeKwonDo at 10 and earned a second degree black belt at 16. In high school, I captained the varsity marksmanship team, competed on the JRTOC Raider Challenge Team, and played varsity soccer. After high school, I studied Goshinbudo Jiujitsu, Muay Thai, and MMA as well as played racquetball, intramural softball and football while studying Chemistry and Physics at the University of Georgia. I opted to pursue academia rather than a career in mixed martial arts and earned a Doctor of Pharmacy from the University of Georgia in 2009. Today, I enjoy backpacking, scuba diving, and pickleball with my wonderful partner, Staci.

Scott

My passion in life is to inspire children to live a life of compassion, self-discovery, empathy, resilience, emotional connection, integrity and fun. My coaching career started when I was just 10 years old, when I volunteered to help younger swimmers on my swim team. Over the years, I’ve discovered that (aside from my son) two of my most favorite things are teaching children how to read and play sports! I believe that playing sports can be a positive experience for everyone when respect, sportsmanship and teamwork are the focus. I enjoy helping youngsters from a variety of backgrounds with diverse abilities and challenges. I enthusiastically look forward to each interaction with children because I find it a privilege to spend time with them while honing my skills to create a fun atmosphere and helping each student learn while constantly improving as a coach and leader.

Oliver

I was born and raised in Denver and have been playing sports from a young age. Over the years, I have played football, rugby, soccer, golf, tennis, and lacrosse. I’d have to say that golf has always been my favorite though so when I discovered the TGA Golf program, I knew it was the right fit for me! It has been such a great opportunity and I’ve discovered how much I enjoy working with kids. I’ll be a Senior at South High School this year and planning to attend the University of Wisconsin for my undergraduate degree.

Hello! I’m Maggy! I’m from Pawtucket, Rhode Island and grew up playing tennis, basketball, and softball. I studied Sport Management for undergrad at Syracuse University and Broadcast for my masters. I moved to Denver with my dog, Bucci, and am employed full time in social media. I joined the TGA team because I missed teaching kids Tennis and want to share my passion for my most favorite sport with others!

maddie

Hi, I’m Maddie. I recently moved here from South Dakota and work as a speech-language pathologist. Sports have always been a big part of my life. In high school, I played volleyball, basketball, softball, and track, and later joined the golf team. I love coaching and teaching young kids, helping them develop skills and a passion for the game. There’s nothing more rewarding than seeing a player achieve the success they’ve worked so hard for all season.

kim

Hi there! I’m Kim! I was born in Denver then grew up in Virginia, but decided to move back to Colorado as an adult. I have a huge passion for tennis & golf and love sharing my passion with kids! I was on my high school tennis team for 4 years and currently participate in a women’s 9-hole golf league…which I absolutely love! I’ve been with TGA for almost 5 years now and believe that our curriculum and coaching style sets kids up for success and a lifelong interest in tennis and golf!

kevin

I grew up in S Florida and went to school at the Uni of Florida. Even at a young age, I loved sports so much that I started a sports club at my high school where we would play a new sport every single week! In college, I also coached a YMCA basketball league and we went undefeated in our first year! I continued to coach that team for another 3 years and it was one of the highlights of my entire collegiate experience! I started working for JumpBunch when I first moved to Denver in 2021, but ended up moving back to NYC for work. I couldn’t stay away from Colorado for long though and when I came back in 2023, Staci welcomed me back on her amazing team of coaches and now I coach all Amazing Athletes and TGA programs!

katya

Hi, my name is Katya and I absolutely love tennis! Currently, I play varsity singles at Thunderridge High School and practice at clubs all over Colorado. I’ve been coaching for TGA for the past 2 years and really enjoying working with children, as well as, partnering up with the other coaches to ensure we’re providing a fun, engaging and mindful learning experience for the participants. Inspiring kids to play tennis is one of my most favorite things and I hope I can continue to do so for many years to come.

Hello, I am coach Juan! I am a student at MSU Denver pursuing a bachelor’s degree in exercise science with a minor in sports management. I grew up playing football, basketball, and running track and field. My experience as a student athlete helped me understand the importance of coaches maintaining strong relationships with their athletes. I’m excited about the opportunity to be a role model within the Amazing Athletes JumpBunch and TGA communities to inspire, motivate, and teach these young athletes about the values of life.

Iliana

Hey, I’m Iliana! I’m from Maryland but moved to Colorado in mid-2023 to start a new adventure with my doggo, Sky. I’m a nationally accredited personal trainer and fitness nutrition specialist. My passion for healthy living was ignited in my late teen years when I started weight lifting and training in Muay Thai. I love teaching and working with kids, and Jump Bunch is the perfect way to introduce fitness and hopefully have a positive, long-term impact in their lives.

erin

My passion for golf started as a toddler. While in high school, I honed my skills, earning the top spot on our team, which then helped me earn a scholarship at Rockhurst Uni. After earning my B.S.B.A., I pursued a Master’s at Avila Uni. Next, I was employed as an assistant to the Head Golf Professional at an established golf resort. While there, I worked with the Jr program, which marked the beginning of my teaching journey. After receiving my Master’s, I became the Operations Manager for the PGA CO Section then launched my own coaching practice! Now, I’m thrilled to join TGA’s admin team as their Golf Manager & Head Coach. My mission is to expand the program, empower children through golf, & inspire fellow coaches to share their enthusiasm for teaching the game.

emma

My name is Emma and I’m so excited to coach tennis for TGA! I’m currently a senior at Highlands Ranch High School and have been on my school’s varsity tennis team since my freshman year. I have been involved in childcare and education for 5 years, and love seeing how fast kiddos can learn and grow in class. Fun fact: my favorite shot is my forehand!

claire

Claire Griffin was a NCAA Division 1 Women’s tennis player at Western Illinois University, where she graduated with a BS in Hospitality Management. She managed restaurants in the city of Chicago for 6 years, overseeing hundreds of employees’ schedules, managing budgets, and training all levels of personnel. While she enjoyed this work greatly, she missed instructing tennis as she had done seasonally while in college. She decided to leave the restaurant world to return to her passion of teaching tennis full-time at her home clubs in Oak Park, and River Forest, Illinois. During the pandemic, she and her husband relocated to Northern California, where they lived off-grid and became farmhands for a family friend. During this time, she still felt the pull of coaching, and took it upon herself to build a small tennis program for the community entirely from scratch. While doing this, she also gained a full year of digital marketing and public relations experience working remotely for her long-time friend’s award-winning marketing agency. In this time, they also welcomed their first child Marshall. Having this wide range of experiences makes for a versatile director! Since moving to the Denver area, Claire has been longing to make a real difference in children’s lives by bringing sports to as many kids as possible. Then along came Youth Athletes United, and she knew this was the right home for her professionally. As the director for JumpBunch and TGA Denver, she will do everything in her power to properly train and equip coaches, be a resource for parents, and bring these incredible programs to as many more schools as possible. Claire understands that greatness can only be achieved when teams have what they need, communicate freely and frequently, and have an open door policy with their chain of command. Only together can we bring the mission of fun and fitness to kids far and wide!
