Riana Galassini Eaton

Owner / Business

and Finance

Riana is a graduate of Alamogordo High School and has been a lifetime resident with a short living stent in Las Cruces while attending New Mexico State University.  After graduating with a double Bachelor’s degree, she returned to Alamogordo to make it her permanent home.  Riana is married to Bryce, and they have two children.  Her love for gymnastics began when her daughter had a passion for the sport, and she wanted to create an atmosphere for others to have a place to go that offered multiple options for not only gymnasts but kids of all sorts.  

Echo Johnson

Owner / Head Coach &

Recreational Director



Echo Johnson has been married for five years to her husband Craig and has four beautiful daughters.  She recently moved back to Alamogordo, where she was introduced to gymnastics by her best friend in the 2nd grade.  Echo was a competitive gymnast for over ten years, in Alamogordo, NM, and Greeley, CO.  She transitioned from a gymnast to a coach as her career began winding down and has had the opportunity to coach at multiple gyms in Colorado, New Mexico, and Texas.  Her favorite part of being a coach is seeing a student get a skill and being part of that "aha" moment, where the drills, conditioning, and perseverance all come tougher to make that moment happen.  Echo is excited to be sharing her love for gymnastics and cheer with her hometown community.  She hopes that Xtreme Amplitude becomes a place that not only teaches student skills for gymnastics but also helps them to succeed in all aspects of their life.
