Meet the Team

Ronnie Oswald – Owner, Head Coach and Personal Trainer

Passion for People: From day one of his professional career, he has been dedicated to improving the lives of his clients. Prior to his personal training career, he was a child services social worker for the state of Missouri. His desire to help children and their families find a better life was not enough to make a difference in an understaffed, bureaucratic government agency.  To his pregnant wife’s initial dismay, he quit his state job and began a fresh start as a personal trainer. Fitness and health had been a hobby, but as he built his clientele base, he discovered in personal training a fulfilling career as he helped people improve their quality of life.

He has worked with every type of client imaginable, from recovering couch potatoes, to triathletes, to figure competitors. Ronnie has a love for fitness and lives it in his everyday life, always experimenting with his own personal workouts, incorporating his experience to help members reach their goals. He has the unique ability to connect with people of any personality and background to inspire and motivate them to be their best. Upon discovering CrossFit programming in 2009, he found an even more effective and fun way to help people be their best. He loves sports; working with athletes to help improve their sports performance while also helping them develop self discipline and foundational life skills.

Education and Experience:
Ronnie has been a certified personal trainer since early 2007, servicing over 5,000 training sessions while holding various nationally recognized personal training certs like ISSA, NESTA, and AFAA. He is currently Level One CrossFit and CrossFit Weightlifting certified. And hey, he is not some certified meathead, he’s actually a college graduate, with a Bachelors in Sociology from University of Missouri Kansas City.

The Guy Behind Sky’s Limit CrossFit: There’s a lot more to Ronnie than CrossFit and tattoos. He’ll claim his favorite movie is Gladiator, but secretly, it’s Urban Cowboy. He’s a fan of hard rock and country music, mixed martial arts, hunting/archery and big obnoxious trucks. You’d think he’s some kind of tough guy based on all that, but then you haven’t seen him with his two daughters, Skyler and Layla. He’s a strong guy with a big heart, who’s driven by the journey to health, fitness, and happiness, not only for himself, but for his family, friends, and clients.



Sean Russell – Coach/Firefighter

A.k.a. “Big Scene” was born in Kansas City, MO and raised in Overland Park, KS. He dabbled in the whole gamut of team sports growing up, but finally settled on a single sport, baseball, in high school. Sean was recruited out of high school by Avila University, right here in Kansas City, and pitched for the Avila Eagles throughout his college career.

Subsequent to college graduation, and due to a lack of exciting career choices relevant to a B.A. in Sociology, Sean was compelled to serve his country. He enlisted in the United States Air Force and served as a paratrooper/ROMAD (Recon, Observe, Mark and Destroy) in a TACP (Tactical Air Control Party) unit. He was stationed at Pope Air Force Base in Fayetteville, NC and was aligned with the 82nd Airborne Division at Fort Bragg.

Upon completion of his military service, Sean worked as a volunteer firefighter and earned his Firefighter and EMT certifications. He has worked as a full-time firefighter ever since and has been with the Lenexa Fire Department since 2007.

Fitness Inspiration: Sean has been committed to fitness ever since he was bullied one sunny afternoon while walking home from grade school; he was determined to never allow that to happen again. As a collegiate athlete, the desire to remain competitive and produce favorable results was the motivation to be fit. As a paratrooper and now as a firefighter, the motivation to be fit is survival, not only his own, but that of his crew; the main goal being to make it home to his wife, Heather, at the end of each and every shift.

Sean has been exposed to a variety of fitness regimens throughout his athletic, military and firefighting careers. He was introduced to CrossFit while attending the firefighting academy for the Lenexa Fire Department and never looked back. Sean loves CrossFit, not only because of the obvious health and fitness benefits, but because of its competitive nature. In 2016, he qualified for the CrossFit Games Masters Regional (age 40 – 44) competition. Sean became a CrossFit Level I certificate holder in April of 2012 and CrossFit Weightlifting in 2014. He has also been a National Strength and Conditioning Association Certified Personal Trainer for several years.

Big Scene’s inspiration is rooted in his faith. He believes that anyone who has been blessed with a healthy mind and body should always strive toward perfecting these gifts through hard work and perseverance. Sean hopes that through his coaching, he will not only be able to inspire others, but to help them make their fitness goals become reality. There is nothing more gratifying, from a coaching perspective, than to witness someone accomplish what they had set out to do; or to even achieve a task they had previously thought to be impossible.

When Sean is not at the fire station, coaching/training at Sky’s or teaching CPR, he spends quality time with his wife Heather and their three cats, Tito, Gracie, and Pee-Wee.


  1. Hi,

    I was wondering if you guys had a drop-in policy. I have been doing crossfit for three years or so and love to catch work-outs when I am on the road. I was hoping to potentially catch you 7PM tonight or definitely a workout tomorrow.


    • Normally we have people buy a t shirt but we are all out so it would be $15. If you are here multiple days I just have people pay 1 time and then just come in and join us for the week. Hope to see you soon.

  2. Ronnie & Jesse, thanks for the outstanding WOD! I am definitely feeling the aftermath of the ringdips- good pain! We’ll definitely be back for more. Thanks again for the coaching and motivation.

    Semper Fi,

    Erik J.

  3. Awesome write up guys, thanks! I need to get a good pic of myself for the bio.
