1/5/2015 Re: Reference letter for Tammy Clark From: Tony Roussey, Vice President of Operations/Safety Director To whom it may concern; Tammy Clark has provided Elzinga & Volkers (E&V) with over the top safety consulting services for over three years on numerous construction projects. As a General Contractor/Construction Manager working throughout the midwest, E&V, aided by the training and guidance of Tammy Clark, has achieved some significant safety milestones. Going into 2015, E&V has worked over 2,800 consecutive days and over one million, one hundred thousand man hours without a lost time injury! If it were not for Tammy’s training, passion, knowledge and focus on employee safety, I am certain that number would have been very difficult to achieve. E&V was also selected the top safety contractor by the ASA chapter of subcontractors, in both 2013 and 2014, the only years the voting was presented. In addition, E&V was voted the Associated Builders and Contractors Safety Contractor of the Year in both 2012 and 2013. I believe strongly, that Tammy played a major role in that success. If I were to recommend any of the safety consultants I have partnered with in my career, Tammy would be at the very top of that list. Please feel free to contact me any time to discuss Tammy’s services at the number listed below. Respectfully,

Tony Roussey VP of Operations
