Meet Our Team

Administrative Team


Sarah Wolfer


Sarah started this company because she is passionate about women supporting women, leadership, and the many benefits of sports – and here at Girl Boss Sports she was able to combine all three! She has been a soccer coach for 16 years now and has consistently found a lack of female coaches no matter the geographic region where she has coached. Research shows that this is not just an issue in the sport of soccer, but across most others as well! This is an area Girl Boss Sports makes a difference in through recruiting passionate female coaches and athletes and providing training and ongoing development for all Girl Boss Sports coaching staff.

Sarah has also found that every time she coach a girl’s team, she is able to connect on a deeper level with the athletes as she understands the unique experience it is to be a female athlete growing into a young woman. It is this knowledge and experience that she is excited to share with other female coaches and athletes through the reach of Girl Boss Sports. Sarah is also a Licensed Independent Clinical Social Worker (LICSW) which has given her knowledge around learning theories, child development, and mental health that have increased her skills in the coaching realm as well.

Currently, Sarah also plays for the Oregon Ravens Professional Tackle Football Team. As a current professional athlete herself (and former semi-professional soccer player), Sarah is able to relate to the athletes she works with on a different level.

All of this combined with her 26 years of experience playing the beautiful sport of soccer have led her to where she is today – making an impact on the world by changing the life of one girl at a time.


Mandi Marquardt

Administrative Wizard

Mandi’s love for the beautiful game began in 1998 in France while she was playing street soccer with local youth. Her main athletic focus for 18 years was the sport of Figure Skating, but along-side that she continued to play and develop skills in soccer. Ten years ago she was sidelined from figure skating due to injury, and found a new home in the sport of soccer, where she has been able to apply the same passion, focus and love for learning and improving technique and skill constantly.

Mandi is an NASM certified personal trainer and Performance Enhancement Specialist, and plays indoor soccer multiple days a week primarily at the positions of midfielder and goalkeeper. She has been a gameday volunteer with the Seattle Reign/Reign FC since 2016, serving on the stretcher crew, retail, and game day field and stadium set up positions.

She loves coaching for the opportunity it gives her to share everything that she learned, not just from soccer but also from figure skating and personal training. Sports are about preparation, dedication, and fun. Even when learning skills that are daunting or that may not be your favorite, it’s important to find ways to keep your mind and body engaged and connected to the joy of sport.


Sylvie Aibeche

Marketing Director

Sylvie has had successful career as a business consultant and a marketing executive for more than 10 years across many industries. She wants to spend her life with purpose and have an impact on the world and decided to bring her strong business background to Girl Boss Sports to help women’s sports to thrive, empower the future generation of women, and set up positive female role models for girls but also for boys.

Sylvie created Stronger Together a Marketing and Branding agency to help develop women’s sports by giving solid tools and more exposure to female athletes and teams and to help companies such as Girl Boss Sports to change the status quo.

Sylvie started playing soccer as a kid in the south of France. She was the only girl among boys, but despite that she was the most physical player on the team. She was made team captain during all her career due to her tremendous leadership ability. She remembers her dad telling her to choose another sport as there was no future for girls in soccer, but she decided to follow her passion nevertheless. Since then, she has faced even more adversity as a woman playing football, a sport that is also typically seen as one solely for men.

In 2012, Sylvie fell in love with American football, has played 10 seasons internationally and currently is a quarterback and safety for the legendary DC Divas. Sylvie is fuelled by all the positive impacts sports can have on people and society. She was a Head coach and Offensive Coordinator for high school football in Paris and was amazed by how the future generations of men are inspired and look up to female coaches. The future is bright!


Taylor Herman

Director of Business Development & Operations

As Girl Boss Sports aims to position itself as a company that is disrupting the sports industry and fighting for more inclusivity and equity for female athletes, we have brought Taylor Herman onboard as our Director of Business Development and Operations.

Taylor brings a strong business and operations acumen, as well as a background of being a life-long athlete herself. She started playing sports at age 3, and has been a multi-sport athlete for most of her life, but focused on basketball through elementary and middle school. She also started training in Taekwondo (Korean martial art) when she was 12, and by the age of 16 was a black belt competing at the Junior Olympics (where she would become a double gold medalist), so elite sports training is no stranger to Taylor. She also played collegiate soccer in South Korea at Yonsei University, and continued playing semi-professionally when she moved to Seattle in 2016. She now plays professional women’s tackle football for the Oregon Ravens in the WNFC.

Being in the sports world for almost 25 years, Taylor has realized the gaping divide between male and female athletes and their coaches and trainings, and jumped at the opportunity to combine that background with her business knowledge to help forward the fight of Girl Boss Sports. She hopes that she can support Girl Boss Sports to give girls of this generation the opportunity to compete on an equal playing field that she could only dream of when she was young.

Katrina Guerra

Director of Coaching

December 2004 the Colorado State Rams took on Tennessee-Martin, led by 5’ 3” point guard Vanessa Espinoza. It may have just been another game for Vanessa Espinoza, but for one 14-year-old, it was the first time she had ever seen a female compete in a sport. That 14-year old girl got to watch an athlete that looked just like her dominate in a sport she loved, and her life was forever changed.
That 14-year-old girl went on to continue to play basketball through her high school career, lettered in softball, played flag football in college, and is currently the quarterback and captain of the Oregon Ravens Women’s Tackle Football team. She also never forgot the impact that the strong, female role models had made in her life, so she became a coach as well; for the first time as a junior in high school and continues to this day. It wasn’t until she started coaching girls that she realized the impact she could have on the future. She saw herself in the girls she was coaching and wanted to give them the best shot at success.
Katrina Guerra joined the Girl Boss Sports team because her passion for sports and empowering the future generation of female athletes is directly in line with the mission of the company. She has finally found a place where she could do something she loves with an amazing group of women that have the same passion. She cannot wait to see how she can be the positive change for girls and women around the world.

As an OUT and PROUD transgender athlete, Erica also serves as an Athlete Ally Pro Player Ambassador for Athlete Ally, an organization that is on a mission to end the rampant homophobia and transphobia in sport and to activate the athletic community to exercise their leadership to champion LGBTQIA+ equality.

Stories should be told in order to make an impact on the next generation of female athletes.

This entails being on standby during matches, ready (with a stretcher) to carry any injured players off the field. Hannah always tells people that as long as she doesn’t have to do her job, she’s doing a good job.

Equality and inclusion should be a given in our society. Unfortunately it isn’t. Hannah. believes Girl Boss Sports is a leader in leveling the playing field. She is constantly inspired by what Girl Boss Sports does and is excited for what the future holds for this awesome organization.

Marann Leuck


She has been interested in photography since summer of her 8th grade year. From there her passion has grown. She started out with a point and shoot but later on in life her Jr. year of high school she joined yearbook where she would take pictures of the sports team for the pages. She photographed baseball, golf, but mainly football games. She grew up around her brother always playing sports so football and baseball have been a big part in her life. Her interests now are concerts but she joined GBS because I want to get back into shooting sports. Photography has always been a passion for her because you can never relive a moment twice so she loves to try and capture it. Being the photographer for GBS she wants to capture the memories for these amazing girls/women! She wants them to look back at the photos and be like damn I did that, or just remember all the good times they had while playing. GBS has a great team who’s dedicated and has a very great goal that she loves being apart of! The world doesn’t have enough women coaches and she learned that while growing up only watching guys play sports, only have the dads help out with the coaches/being a coach. She hopes being apart of GBS she can help motivate the girls while also capturing the amazing moments they have on their teams.
