What does a typical day look like for you at Polyco?
It’s always interesting, never a dull moment and a good thing about it is always fast paced in a good way. In my current position, I provide our clients with our paving materials that they need to produce based on state requirements. My expertise is polymer, tire rubber, or combination modified asphalt.
What did you do before your current position?
I’ve been in the paving business for more than 25 years. Most recently, I was a senior research developer at Polyco for eight years. Before that, I worked at another asphalt company.
What do you like most about working at Polyco?
The opportunity to be creative and getting support for my ideas. Our quality is excellent, and customers are very satisfied and happy. We believe in our customers; the quality of our material and we don’t cut corners. We deliver what customers are asking for.
What are you most excited about at Polyco?
Working with upper management and customers to come out with solutions to solve the issues that customers are facing. For example, cracking and separation issues, storage stability and other things that they have not recognized yet. Solving problems.
Why is sustainability important to Polyco?
Improves the quality of our lives, ability to develop without depleting natural resources. By presenting better asphalt that would last much longer and will not harm the natural environment. Being sustainable, we’ll be able to save taxpayers quite a bit of money by not redoing the work that has already been performed well. We’re dealing with the state and local communities. This will improve trust and engagement between Polyco, states, and local communities. Sustainability is the key to a better future.
What does the future look like for Polyco?
Proud. We are well positioned to develop products that would be better than anything else on the market. Sigmabond is a great product and, hopefully, within the next 10 or 15 years, we will be able to make existing materials last much longer than any other product out there.
What do you love to do outside of work?
I love traveling to different places, different countries, getting to know and understand different cultures. When I was younger, I used to go skiing and ice skating.
