We have a staff of over 30 people, including engineers, technical, and office support. We are registered and currently practicing in Alberta, Saskatchewan, Manitoba, Ontario, and New Brunswick. Our office is structured to match our philosophy that our mechanical and electrical service should be as integrated as possible. We have done this by integrating design and production systems, and structuring the office layout and activities to enhance crossover and collaboration. Our team approach also benefits from regularly scheduled internal training and production meetings in addition to with social events such as regular office lunches, potlucks, and lunch-hour foosball games.
