David Millard, President

I joined the Stone Marketing Group with almost 30 years of experience as a Manufacturers Rep in the commercial construction products business. Having been an owner in these rep businesses, I know what it takes to service customers and vendors with a high level of teamwork and satisfaction. When I’m not working hard to assist employees, customers, or vendors in finding success, you will find me playing hockey, out at the family cabin, or trying hard not to be the worst golfer in my foursome.

Gary Stone, Director of Sales and Business Development

My career in the rep business started in 1979 with Nathan Weiner & Assoc. I expanded my knowledge of our customers, vendors, and products, and then bought the agency in 2004. At that time, the name was changed to Stone Marketing Group. While I am 100% committed to our business, I also enjoy heading out to the greens for a round of golf and a nice bike ride. Most of all, I love my family and spending time in the hot sun.

Ben Ablan, Director of Operations and Sales

I have worked in the retail business for over 25 years.  This experience combined with my motivation and analytical nature give me my leading edge.  Most important to me are the relationships I build with my vendors and customers which are treated with honesty and integrity. In my free time, I enjoy playing golf, projects around the house and spending time with family.

Trudy McAdams, Account Manager

I have spent the majority of my career working in the retail and marketing space. One aspect that I greatly enjoy is taking a customer’s vision and collaborating with our vendors to develop product and then see everyone’s hard work come to life on the shelf! Personally, I’m a coffee enthusiast who thoroughly enjoys a good cold brew or café mocha!

Chuck Levey, Sales Associate

I have over 40 years of sales experience in the Missouri, Kansas, Iowa, and Nebraska marketing area. Through my extensive traveling in Asia, I've gained thorough knowledge of the manufacturing and distribution process and how it relates globally to the domestic marketplace. On the weekends you will find me spending quality time with my family and my trusty sidekick, Millie the dog. 

Sara Mark, Account Manager

I come to Stone Marketing Group with an array of experience in retail, customer service, and sales. I enjoy finding ways to help different customers and vendors to get the best job done. Outside of work, I absolutely love getting outside, traveling, finding the best vegan food, and most importantly- spending every moment I can with my dogs, cats, and partner.  

Sharon Raskob, Executive Administrator

I have been with Nathan Weiner & Associates/Stone Marketing Group for 38 years and enjoy the relationships I have built with our customers.  Though a lot of changes happened over the years, one thing that hasn’t changed is the pride I take in striving to meet the needs, expectations, and deadlines of our customers on a daily basis.  I believe that every customer’s experience should be a positive one. I am fortunate to be working with a great team of talented and dedicated individuals, who make my job a fun and a great place to work. In my free time, I enjoy biking, water activities, traveling, and spending quality time with my family.

Mazie Ventura, Account Manager

After I received my degree in 2016 from the University of Minnesota, Duluth, I was drawn to customer-facing positions and have spent the last seven years in customer advocate roles and sales. I am passionate about bringing people together and working towards a common goal. I recently moved to Wyoming and have been enjoying the mountain life! In the winter, you can spot me on my snowboard at Targhee Resort, and in the summers, on my paddleboard with my dog, Rio.

Karen Patterson, Administrative Assistant

After completing a 25 year career in the Financial Services Industry, I worked in Retail, Office Management, as well as taking Global Business Communications courses at Bethel University. As of recently I joined the Stone Marketing Group as an Administrative Assistant. I enjoy shopping, therefore, learning more about the products I see in the stores and the vendors of those items is exciting to me!


Personally, I have been married 28 years, I have 2 grown boys, a dog, and I cat. I love being outside so you will either find me in the gardens until dark, kayaking, camping, or snowshoeing! I also love to volunteer and as a bicyclist and have completed many MS Trams and MS 150’s.
