Owner / CCFT-L3 / Nutrition Coach

Kellie Wunsch

I have a background in competitive team sports (softball and soccer). I was introduced to CrossFit in 2011 from one of my teammates and finally joined a CrossFit box in 2013. I immediately loved the team spirit & the community that CrossFit offers and I have continued to grow in the sport.

As a Master's Athlete, I recognized that proper nutrition, training, and recovery was important to avoid injury and have longevity in the sport. I am committed to sharing the value and benefit CrossFit has to offer to all ages and help athletes reach their own personal goals.

Owner / CF-L2

Todd Wunsch

In 2009 I was introduced to CrossFit in Encinitas, California. A short time later I was introduced to Rugby Union where I took on both playing and leadership roles within the sport. I received my USA Rugby L1 Referee Certification in 2014 and later went on to obtain my CrossFit L1 Trainer Certification in 2015.

After joining Aliso CrossFit in 2015, my passion quickly shifted to CrossFit helping people fight off metabolic disease and improve overall physical and mental health. I received my CrossFit CF-L2 Level 2 Trainer certification in 2021 and my CrossFit Weight-Lifting (Burgener) certification in 2023. I am committed to the CrossFit Community and educating overall health and fitness through the CrossFit core principles.

Regis Saalfeld

I am a Brazilian, undergraduate and postgraduate from the Federal University of Physical Education in Brazil and I am now a CrossFit Level 3 Trainer. With almost 20 years in the field, I specialize in exercise physiology and personal training and love to have fun in the big classes. "I see the CrossFit methodology as an excellent opportunity to generate autonomy throughout our lives and improve, not only our physical body, but also our mental, social, and spiritual aspects."

Andrew Corona

I currently reside in San Juan Capistrano, CA with my wife and our beautiful Weimaraner puppy Enzo. I have enjoyed active sports in my life including rugby, golf, and CrossFit. I started CrossFit in 2013 in Boston MA and I have grown with the sport and coaching ever since. My life's travels have taken me through New Mexico, Colorado, and now Southern California.

I am a big Denver Broncos fan. I obtained my CrossFit CF-L1 certification in 2021 and I absolutely love coaching and teaching all levels of individuals and groups the importance of moving well with relative intensity. I particularly enjoy bringing fun and excitement to each and every class that I coach.

CF-L1 / Nutrition Coach

Aileen Slivkoff

I grew up in Southern California and enjoyed an active lifestyle engaging in softball, volleyball, and cheerleading. As an adult, my interest shifted towards distance running while participating in multiple long distance running races annually. In early 2012, I was introduced to CrossFit as one of the original members of Aliso CrossFit.

Sparking a newfound passion, I attained my CrossFit Level 1 Trainer (CF-L1) certification in 2022 and now I find fulfillment in coaching and helping individuals reach their goals. I have a particular interest in master's women and their journey towards longevity. This passion aligns seamlessly with my extensive experience as a women’s health nurse practitioner spanning over two decades. I currently reside in Aliso Viejo with my husband where we raised our two beautiful daughters.

CF-L1

Liz Kelley

As the newest L1 coach, I'm proof that questionable life choices can lead to great things. After 10 years of doing CrossFit—all of them right here at Aliso CrossFit—I decided it was time to move from the whiteboard to the coaching floor. I proudly put the "fun" in functional fitness and believe that suffering is always better with friends. Expect plenty of encouragement, probably a few bad jokes, and a very high likelihood of spontaneous dancing during class. Outside the gym, I'm a proud dog mom to Presley and a firm believer that everything is more fun with good people and a good playlist.
HYROX-L1 Certified Coach

Eric Ritossa

Eric brings a lifetime of athletic competition and a genuine passion for helping others reach their potential. He competed in football, basketball, and track in high school before going on to complete both a half marathon and a full marathon. Most recently, he has taken his fitness to the next level by competing in four pro-division HYROX competitions, a format that demands a rare combination of strength, stamina, and mental toughness.

Backed by his HYROX Foundations Course and HYROX Level 1 Certification, Eric has the knowledge and methodology to coach athletes of all levels in HYROX-specific training and race preparation. He coaches with the same intensity and commitment he brings to his own training, meeting each athlete where they are and pushing them toward what they’re capable of.

When he’s not in the gym, you’ll find him doing his best to keep up with his three kids which, if you know Eric, is a workout in itself.
