I have been with Biewer Lumber LLC and Pine River Group for over 35 years. In that time I have held positions in inside sales, outside sales, and plant manager of the St. Clair treating plant for more than 10 years. My years of experience in wholesale lumber, poles and piling and treating give me a unique perspective on working in the area of commercial sales. I am proud to have been the first person involved in what is now the Pine River Group and have enjoyed watching the division’s growth and success over the years.

Outside of the company I enjoy watching all sports, having played recreational softball for 30 years until the knees gave out. I love golf and plan to take my talents on the Senior PGA tournament upon retirement.

I’ve been with the company for 13 years now, most of which was spent in the Sawmill Sales division of our parent company, Biewer Lumber LLC. I held multiple positions during my tenure there, including Sawmill Sales Manager and then when our new mill was built in Newton, Mississippi, I took on a more southern-focused sales role that sought new business opportunities and overall expansion. In January of 2018 I was asked to start a new division of our company, Biewer Trading, which aimed to bring more value to customers by expanding our offering outside of what can be considered our company’s “comfort zone.” That kind of out-of-the-box thinking and arena for creativity is something I love and thrive on. This role grew naturally to include the opportunity to work with Pine River Group on government projects, which, at that point, was a world our company had not been actively involved in. The dual-role I find myself in is fast paced, collaborative and very customer-centric which has proved to be the perfect combination for me – I consider myself very blessed to be where I am, with the team we’ve built, for a company I respect.

When I’m not in the office I’m usually staying active as a husband and father generally does. I have a beautiful wife and daughter, with another child on the way. I also enjoy camping, water skiing, golfing and working out.
