Graham started his work with the SDI team in 2012 right after graduating from NAIT’s Occupational Health and Safety Diploma program. He worked with a wide variety of clients for three years before taking some time to work in the non-profit sector. He rejoined SDI in December 2018. Graham’s approach to creating customized solutions is backed by all of that experience and his prior background in technical writing and computer software support. He is passionate about making sure that all of the occupational health and safety management systems he builds don’t just meet or exceed various requirements, but also that those systems are completely compatible with the client’s process of delivering services or products. In other words, Graham loves to avoid creating “more paperwork” when it’s possible to meet and exceed standards with a more streamlined approach.


Outside of his everyday work, Graham is currently working towards obtaining his CRSP designation and enjoys spending his time off with his spouse and their three cats.
