Alumni Testimonials

RSI is everything they say they are

I attended RSI MME Program. I was in class 9 months and online for 6. Although due to health reasons I have not been employed yet with the awesome team that career services has I would have right away. Now almost 2 years later, they haven't given up. I still get every email with all job opportunities and frequent calls. I am ready to work. Good thing they offer free lifetime classes because I will be doing refresher classes while they help me look for work. I am very confident that I will have me placed in a job soon,. I wouldn't change my decision of choosing RSI over other programs offered at other schools.

Great experience

After attending RSI it was not long for me to locate a job even though I was looking out of Phoenix and the career department didn't have many out of area leads. After working for a year or so and seeing other people hired right out of school (not RSI) I realized how lucky I was to attend this school. I know have great opportunities that a lot of the time come to me so I am not looking for a job but jobs are looking for me. If you don't mind sweating, getting dirty, and working hard RSI will definitely put you on the right path for a job in HVACR.
