The Phoenix, Arizona campus has trained skilled trades professionals since 1965, when it opened as a school specializing in HVAC and refrigeration training. It later operated as The Refrigeration School, Inc. (RSI) and was acquired by StrataTech Education Group in November 2009. On July 20, 2026, the school changed its name to Tulsa Welding School and now operates as the TWS Phoenix campus, joining TWS locations in Tulsa, OK; Jacksonville, FL; Houston, TX; Dallas Metro (Irving, TX); and Atlanta Metro (Decatur, GA) under one shared brand and one unified network of six campuses.
The mission of the TWS Phoenix campus, consistent with the rest of the TWS network, is to provide students with the hands-on skills, knowledge, and attitudes necessary for entry-level employment and professional growth in the skilled trades. Training emphasizes practical, job-ready instruction that can be completed in as few as seven months.
Combined across all six TWS campuses, including the Phoenix location under its former RSI name, the school network has an estimated 60,000-plus graduates and employer relationships across more than 16,000 companies nationwide.
The Phoenix campus is designed for adults who are ready to make a career change, start a first career in the trades, or earn a credential to advance in their field. It primarily serves three types of students, consistent with the rest of the TWS network:
Career changers - adults leaving unsatisfying or unstable jobs who want to enter a skilled trade with strong demand and earning potential.
First-career starters - recent high school graduates, GED holders, and young adults who want a faster, more affordable path to a stable career than a four-year degree.
Military veterans and transitioning service members - individuals applying their discipline and work ethic to a new civilian trade career, supported by GI Bill and other military financial aid.
The Phoenix campus's core value proposition is speed, affordability, and hands-on practicality. Most programs can be completed in seven to fifteen months, financial aid is available to those who qualify, and training is hands-on and job-focused from day one.
