The Arizona Local Masters Swim Committee (LMSC) is the official agent for USMS, governing master’s swimming in the state of Arizona. It was formed in 1973 and consists of the entire state of Arizona.

Over 1100 adults of all ages are members of our LMSC. They range from college students, professionals, military personnel, business owners, educators, senior citizens, and all other walks of life. Some are former competitive swimmers, others are triathletes, and many are simply fitness swimmers who enjoy staying fit. Some swim on their own but the majority train with one of over forty teams located throughout the state.

Arizona Local Masters Swim Committee (LMSC) is a non-profit, tax-exempt organization that operates as a subordinate unit of United States Masters Swimming. It is recognized by the Internal Revenue Service as a 501(c)(3) organization.
