Degrees and Certifications:

Mr. Gabriel Teixeira

My name is Gabriel Teixeira. I have been teaching HVAC/R at Diman since August of 2016. I am a part of Diman's class of 1999, graduating from the Electronics Technology shop. I worked in the Telecommunications field for my original Diman co-op employer for about 5 years before realizing that I was unsatisfied with that career path.

I decided to pursue a career in the HVAC/R trade for a number of different reasons. The HVAC/R trade is challenging, rewarding, and impactful. I was able to have a major positive impact on many people's lives. I worked in the HVAC/R trade for over 12 years in MA and RI before I became a teacher at Diman. Now as a teacher in the HVAC/R trade, I could not ask for a more rewarding and impactful career. I take the task of helping students become great HVAC/R technicians and exceptional young men and women very seriously.

-Massachusetts Refrigeration Contractor license

-Mainstream Engineering EPA 608 Universal certification
