In an explosive market, Pine River Group provides a measure of certainty.

While the Pacific Northwest has long been considered the traditional growing region for hops, the industry has seen nationwide growth for the past several years. With U.S. hops production reaching 87 million pounds last year (2016), it comes as no surprise that at 30+ states have now become players. Michigan alone has over 140 breweries, which has boosted demand for locally grown hops drastically.

Being located in the heart of the Midwest, Pine River Group understands the need for top quality agricultural products. We are proud to be a part of this market's growth by providing structurally stable posts to new yards and growers across the region. We strive to provide solutions to questions before they’ve even been asked — an approach that has allowed us to build an extensive portfolio of satisfied customers.


"Pine River Group is flexible, communicates well and helps make us more productive. They make it happen and get the job done!"

In 2015, the United States consumed almost one billion gallons of wine. This consumption has been growing steadily for the past 75 years, which has led to the rapid growth of US vineyards and wineries.

Many might be surprised to learn that the Midwest is a large participant in this rising industry. In fact, the Midwest is home to the largest concentration of wine trails in the country: 55 out of the total 274 trails.

Successful vineyards know that to produce the best quality grapes, attention to detail is a must in every aspect of their crops. This is why so many prefer the stability and superiority of Agri-Max wood posts to support their trellising systems. With Agri-Max wood posts, wire & cable, and Gripple, we offer a measure of certainty to your operation.

Cable & Wire

Imported cable and wire material have been known to contain lead and other harmful contaminants. Pine River Group understands that only the best products should be used for our vital farming industry. While it is conceivable that foreign rod and wire for strand is lead patented before wire drawing, lead can also be used to cleanse drawing lubricants off the wire surface prior to galvanizing. Therefore, Pine River Group offers only USA-made cable and wire that is very competitive in price to its imported counterpart, meets ASTM Specifications and, most importantly, safe to grow on.

My career began after graduating with a Bachelor’s Degree in International Business from Gannon University, where I was an active member of the Women’s Swim Team, specializing in distance races. While enrolled, I interned at a luxury golf course in Erie, Pennsylvania where I refined my skills in business administration and customer account management. Shortly after graduation I started my career at Pine River Group in early 2017. In my current role I support all of our divisions, with a concentration in agricultural sales, through administrative processing and account detailing. What surprised me most about Pine River Group is the level of professionalism and strong sense of camaraderie; PRG is more than a company, it’s a family and I am very grateful to be part of such a wonderful team!

Outside of the office I love spending quality time with my family, friends and five cats – crazy cat lady and proud! I also enjoy going to concerts, traveling, running, baking and watching the latest box office hits.
