Employee of the Month

Meet Ralph


Ralph is our Heating Manager and has been with G.M. Mechanical for just over 7 years! He is a journeyman sheet metal mechanic who has over 30 years of experience in the trade! The one thing I want to mention about Ralph is that he isn't your typical "installer". He actually cares about every job he does in trying to make it functional as well as esthetically pleasing. He does excellent fabrication work in the shop which shows the difference between having properly installed ductwork can make on proper airflow!

He currently lives in High River with his wife but has been in High River for 22 years. He has 4 kids that all grew up in the area as well.

He states that the favourite part of his job is, "The variety of jobs to be done. No job is exactly the same and every job is a new learning experience."
