Who We Are

Why We Are Here

Sender One’s purpose is to discover ourselves and connect with others through climbing.
Every individual who climbs with us has a unique story. We vow to foster a space that offers inspiring climbing, yoga, and fitness experiences; an opportunity for self-discovery, and a sharing, social atmosphere for every member, new visitor, guest, and partner who walks through our doors (or who we meet outside of our doors).

What We Believe In

Who We Are

Alice Kao

Co-Founder, CEO

Alice discovered climbing while living and working in London in 2008, following a difficult breakup. She was inspired by the healing and self-discovery that climbing brought her, which led her to co-found Sender One in 2011 upon returning to the United States with her business partners.

Alice hates following rules but loves rallying people to believe in an idea. She wears her heart on her sleeve and is not afraid to cry in meetings. She was born and raised in Taiwan and moved to the US when she was 12. Alice's superpower is her ability to ask for help relentlessly -- because no one has all the answers!

Nicole Pate

Vice President of Operations

Nicole grew up exploring the Santa Monica Mountains but didn’t discover climbing until after college. Her first experience climbing was at the New River Gorge in West Virginia, and she was immediately hooked. Once back home, she honed her new skills in the mountains she grew up in, and shortly after, moved to Costa Mesa where she found Sender One SNA. She started working at Sender in December of 2013 after being a member for a few months. In 2016 she moved back to Los Angeles to open Sender’s LAX location and continues to share her passion for climbing there today!

Morgan Sander

Director of Operations

Morgan connected with climbing and yoga because of their unique combination of mental and physical challenges. With her background in competitive gymnastics and developmental psychology, she became fascinated with the way that these movement practices affect our mental states, encourage creative problem solving and play, and build community. Today, Morgan teaches a multitude of movement activities including climbing, aerial silks, yoga, and acro yoga, and she strongly believes that anyone, of any background, can grow mentally and physically by mindfully challenging themselves through these practices.

Jeffery Tamayo

Human Resources Manager

Jeffrey retired from long-distance running back in 2016 due to destroying his knees. I guess you can say being injured all the time was not the bee's knees. He started climbing more as an alternative. Though he's been climbing for almost 10 years, it will always remain a recreational sport for Jeff. Don't get it twisted - he will try hard on occasion, but don't expect much. Jeff did most of his outdoor climbing when he was living in Yosemite and now aspires to become the best belayer in the world at Sender One. Jeff mostly rope climbs, but he is not a morning person (not sure why those two things would go together, but it felt right for you to know that). Finally, he enjoys listening to people.

Alexandra Erdman

Digital Marketing Manager

Alexandra discovered climbing as a senior in high school to escape pressures of college applications and has been climbing with friends ever since. She joined Sender One as the Customer Experience Manager at Playa Vista in 2021 and has since joined the Marketing team as the Digital Marketing Manager. If you've ever chatted with Sender One on Instagram, it's likely Alex you spoke to!

Alexandra prefers boulders but has been known to rope climb (with enough convincing). Outside of climbing, you will find Alexandra on the slopes in Big Bear or Mammoth, in the yoga studio or on her couch watching criminal amounts of reality TV.

Jae Wu

Financial Analyst

After taking 30 minutes to overcome a simple roof climb in a small highschool wall, Jae knew climbing would be something they would always seek out. Climbing strikes a balance between community, athleticism, and land appreciation, which Jae promotes as a coach and a member of the Sender Team. On rest days, Jae enjoys building out their homebrew world in Dungeons & Dragons, crafting chainmail, and being the very best like no one ever was.

Ian McGarraugh

Santa Ana Gym Manager

A SoCal native, Ian has been climbing since 2009 and has been working in the outdoor industry for about as long. He prefers roped climbing, often switching between sport and trad from season to season. When not climbing, Ian pursues many other outdoor sports, including canyoneering, backpacking, and mountain biking. Every day he gets to connect with new people and loves when he gets the chance to teach people about climbing techniques and technology (almost as much as when he gets to connect about various nerd fandoms).

Art Alvear Garcia

LAX Gym Manager

Art dove headfirst into climbing in 2013, purchasing an annual membership during his second time climbing before working at that same gym only a month later. Since then, Art has integrated himself into the SoCal climbing community, helping to foster the same inclusive and welcoming environment that he felt immediately when exploring the sport. Art is extroverted and social, and can often be found forging new connections with any nearby climbers, at the gym and crag alike. Art loves bouldering, teaching people how to lead climb (though he's scared to lead fall himself), and he especially loves guiding people through their first outdoor climbing experience. He enjoys playing games, anime, cats, and generally having fun with people. If you see him, don't hesitate to say hello!

Mike Rohsler

Director of Routesetting

Mike grew up in climbing gyms and participated on climbing teams in New Jersey with his older brother. The incredible images of Southern California rock climbing plastered around the gym and in magazines set the destination for him. Twenty years of climbing, and nine years of routesetting later he arrived at Sender One, more psyched than ever to showcase his creativity to this community.

Marcus LaCavera

Santa Ana Head Routesetter

Marcus was introduced to indoor climbing during his last year of highschool in 2013; He was immediately hooked despite the torn skin and tired fingers. During his time at UCSB, Marcus discovered his love of routesetting, helped found the school's climbing team, and eventually stumbled upon an online listing for a setting position at Sender One. Nowadays, Marcus splits his time between setting, getting lost in Black Mountain, and playing too many video games.

Climbing is better when we climb together—at work and on the wall. Explore open roles and see if there’s a fit.
