I worked with RMG during my time at Indalex. RMG is a very detail oriented firm and very professional in their duties. They are relentless when improving the safety culture and operations at Indalex Aluminum Solutions. Their dedication to achieve the company Safety goals allowed us to achieve the targets and still maintain our strategic budget guidelines. I would recommend RMG to any future firm who wishes to improve the work and culture Safety standards.

Bernie Lewis

VP & COO - CMC Sisak

RMG was respected for his willingness to help anyone with their “safety first mentality”. They were instrumental in the introduction of company-wide health and safety policies and procedures. Their professionalism and strong leadership skills were demonstrated by his ability to obtain buy in from all levels of the organization.

Georgina Scott

HR & Compensation Consultant

I worked closely with RMG during our time with Indalex. RMG started their operations at Indalex by surfacing and investigating serious safety and WSIB issues at the Mississauga plant. Their skills and professionalism in that investigation provided the Company with critical information needed to change the culture and turn around the safety program. All of Canadian plants benefited from his safety first drive and his detailed understanding of all appropriate regulations, which resulted in significant safety turnarounds at four locations.I would be honoured to have RMG in a organization with me again.

William J. Corely

VP Human Resources - NorthStar Aerospace (Retired)

I had the opportunity to work with RMG in 2007-2008 while serving as the Operations Mgr. for Indalex-Mississauga, Ont. facility. The operation and I benefited from their in-depth knowledge of Canadian HSE and employment law, as well as, the US OSHA regulations. RMG was instrumental in delivering superior safety improvements and performance. In addition to their professional credentials, they was able to leverage an extensive network of Health Care professionals and agency officials to accelerate the facility's EHS improvement targets and goals. They proved himself to be a tireless leader for EHS. They would be an asset to any organizations seeking well qualified EHS professionals.

Robert Gregory

Plant Manager - Bonnell Aluminum

We originally hired RMG to review and update our safety plans, over a short period of time we have also contracted them to manage our human resources and security programs. Their excellent service, attention to detail and subject knowledge is second to none and we would recommend them to any firm seeking to improve their safety and human resources programs.

RMG was our full time safety and WSIB consultant at our Stratford Plant during my tenure at Vicwest, they greatly enhanced our safety training and WSIB claims management systems earning us rebates in all the years I was there. I have no hestitation recommending RMG to any firm that needs assistance in developing or maintaining their safety programs.
