Michael Castillo

Corporate Accounts Manager

Born and raised in Las Vegas, Nevada. Played some football, but mainly wrestled in high school, which brought my encouragement in life toward health and fitness. In college I focused on getting involved in student organizations, which included being inducted into the Sigma Chi Fraternity and holding an office in Student Government. In 1997 I graduated from the University of Nevada Las Vegas with a Bachelor of Arts Degree in Communications, with emphasis in Special Events and Public Relations and a Minor in History. Upon graduation, I expanded my career in special events as the Events Director for the Fremont Street Experience, which then led to becoming Programs Director of the UNLV Alumni Association.

For the past 15 years, I have been a licensed Real Estate Professional, working with commercial and residential investors and property managers. Moving to Ellensburg has allowed me the opportunity to work for Maximus Gym, managing retention and Corporate Accounts, all while getting to know the community and locals alike. Outside of Maximus, I am a husband and father of two incredible teenage  boys. My family and I very much enjoy the outdoor activities the Pacific Northwest has to offer; we also enjoy shooting. Also, I devote time to playing Lead electric guitar for Mercer Creek Church.

Hi there! My name is Raymond, and I am a part of this awesome team here at the Maximus Gym. I am currently working on getting my certification as a strength and conditioning coach so I can fulfill my dream to be an athlete coach. I am an active competing powerlifter, and my all-time favorite exercise is squat. I love working at the gym where I get to meet people with different backgrounds. I definitely want to hear your story because that's what fascinates me most when meeting people. Please feel free to come and chat with me if you have any questions about the club or if you need help with your workout. I look forward to meeting all the members here!

........Btw, squat day everyday lol
