Paseo Club Hero Greg Santilli: Athlete and social justice advocate

February 9th, 2024 | 5 min. read

By Jen Azevedo

Usually, the Paseo Club publishes informative and educational articles based on recent research and the latest trends. Today we will depart from that model to share a personal story about Paseo Club member and social justice advocate Greg Santilli.

Greg’s story is about how one person decided to get fit as an adult for the first time — and the incredible journey it took him on. We also learn how Greg’s mission in life to help others comes from his experience with hardship. 

Greg’s story is both educational and encouraging. We hope you enjoy reading this article about him.

Greg never felt like the sporty type. He was uncoordinated as a youth and rarely was involved in athletic activities. But after years of living an inactive life, he decided to do something about it. 

My fitness journey began in October 2015 when my wife encouraged me to join The Great Results program at the Paseo Club. I was overweight and leading a completely sedentary lifestyle. The Greatest Results program changed my life forever.”

Greg was 51 years old when he joined The Greatest Results. He went on to complete the program — not once, not twice, but thirteen times in a row between 2015 and 2018. 

Paseo Club mentors

Making changes in your lifestyle can be scary. It means trying new things, creating goals, and sometimes failing and having to get back on the proverbial horse.

As we age, this process is less and less enticing. But with the help of good friends and mentors, these changes can be a little less painful.

Greg found the instructors at the Paseo Club to be instrumental in learning how to change his habits. 

“(Fitness Director) Cezanne Youmazzo taught me how to cycle, and most importantly, that the key to finishing very challenging fitness events is ultimately all in your head. She also taught me how to properly recover from grueling fitness events by utilizing cryotherapy and getting stretched professionally. 

Other instructors taught me about endurance, how to have good form in lifting, and a great stretching technique to help with my lower back pain.”

Greg also sought advice about his diet. He tightened up areas that needed improvement and learned that one poor meal choice can completely negate a good workout.

Greg worked long days, but that did not deter him from making time to train. He joined a group known as the 5 am Warriors. 

Working out with other members — many whom were much more fit than Greg — did not discourage him. In fact, it had the opposite effect. He was inspired. 

“I saw so many other Paseo Club members who were in phenomenal physical shape. They seemed to be able to get through the grueling morning circuit workouts with ease. I remember looking at them and thinking, ‘I want to be just like them.’"

Greg’s first quadrathlon

One evening Greg met with his good friend (also Greg) for dinner. Over the meal, Greg (the friend) relayed his positive experiences in participating in quadrathlons. He was so enthusiastic that it got Greg thinking. By the end of the meal he decided he would do the next Mt. Taylor Quadrathlon with him.

After successfully completing the Mt. Taylor Quadrathlon in February 2018, Greg’s friend Greg suggested that they do their first triathlon — the beginner Hermosa Beach Triathlon in June 2018. 

And that is when Greg realized he needed to learn how to swim. 

Did he see that as an obstacle? Nope!

Greg was introduced to Jimmy of Paseo Aquatics and began swimming with Master’s Swim on Mondays, Wednesdays, and Fridays at 4:45 am. Jimmy never gave up on the uncoordinated Greg, and Greg went on to participate in several more quad and triathlons.

He also lost 30 pounds, which he has been able to maintain for the last five years by eating clean, swimming, cycling, running, weight lifting and being disciplined.

After completing the quadrathlon, Greg didn’t go back to a modest workout routine. Instead, he decided to up the ante. 

Here is his current training routine:

  • Mondays, Wednesdays, and Fridays: swim at the Paseo Club 3,200 to 3,500 yards (128 to 140 laps).  
  • Tuesdays and Thursdays: Live Cycle at Paseo or Peloton cycle at home, and/or a shorter run workout (e.g. five miles).  
  • Saturdays: long cycle workout on the Santa Clarita bike paths outside (40 to 70 miles), or Cezanne's amazing Saturday morning cycle workout at 8:30 am, or both.  
  • Sundays: 8-10 mile run on the Santa Clarita paseos or in Pacific Palisades — one of his favorite run venues.

Not just a beast in the gym

When Greg lost his brother in 2005 to suicide, it was a pivotal moment in his life. He decided to dedicate his free time to volunteering for non-profit organizations that provide mental health resources to those in need. 

Since then, he has volunteered at Innovative Housing Opportunities, Didi Hirsch Mental Health Services Advisory Committee, and Saint Kateri Tekawitha Catholic Parish — to name a few.

His role as the Chief Financial Officer of Hillsides is also a huge part of his life because it is where he gets to engage in his greater purpose, “to forever (be) an advocate for social justice and the downtrodden.”

“Hillsides is an amazing non-profit organization based in Pasadena that is dedicated to healing children and young adults, strengthening families, and transforming communities through quality mental health and other comprehensive services and advocacy.”

Greg also uses his Facebook page to share about his fitness journey. He has found that by letting others know about his progress, he can benefit them.

“I use my Facebook page for positive communications only, most of which are focused on my fitness journey. I do this with the intent to inspire others to either start or continue to improve their fitness level. Several of my friends have commented that one of the reasons they have either started a fitness journey or have continued their fitness activities is partially due to my inspiring social media posts.”
