"The SDI Group is the epitome of excellence  in safety support and consulting. David and his group have been  instrumental in assisting us in so many ways and ensuring that we have  all the tools we need to move forward and maintain a Health and Safety  program that not only is right for us but what is expected by legislated  protocols. They have been on site to do audiometric testing and  assisting with policy and regulatory needs. Service is reasonably  priced, done on time and they always have the best interests of the  customer at heart.

They are an outstanding group of individuals that provide excellent  service and is extremely knowledgeable and accommodating. I highly  recommend them!"

"SDI Group did a  last minute chemical sampling for my business in August 2017. They were  prompt, professional and did an excellent job explaining the process  from start to finish. As this was the first time my business had been  required to do a chemical sampling I was very grateful for a team of  people who were willing to work with my limited knowledge. The report  they provided was clearly written and satisfied OH&S. We compared  SDI with competitors and they not only came in at a great price, their  professionalism far exceeded other alternatives."

"Working for SDI  during my summer co-op has been an amazing experience. I was exposed to  so many different experiences and industries during my time here. David  Williamson and Cheryl L’Arrivee gave me every opportunity to learn and  grow as a safety professional. I was encouraged and supported to ask  questions and learn as much as I was able to. I felt welcomed and  appreciated, which is rare to find. The whole SDI team was extremely  helpful and pleasant to work with. I hope to continue my safety career  with SDI Group upon completion of the Occupational Health and Safety  diploma course at NAIT."

"We have been a client of SDI Group for the  last year and we have utilized David Williamson and his team to ensure  compliance with our audiometric testing program. With their mobile van  they are able to test large groups of employees efficiently and quickly.  The technician is very knowledgeable and interacts professionally with  the crews. The follow up reports are timely and concise. I would  recommend this company to any Alberta employer who is wanting to provide  their employees with quality audiograms and meet any OH &S  regulatory requirements."
