Sarah and me.jpgSusan Gordon, Venetucci Farm in Colorado

Susan and her husband, Patrick, have been farming organically for 23 years. Eleven of those were spent managing the 200-acre Venetucci Farm, a community farm on the southern edge of Colorado Springs, CO. In 2016, high levels of PFAS from AFFF used at nearby Peterson Air Force Base were discovered in the aquifer beneath the farm. As this was the sole source of water for both domestic and agricultural needs at the farm, the farm was shut down. Susan and Patrick returned to their farm in Canon City, CO, where they continue to grow a wide variety of vegetables for CSA members and wholesale markets.


Grostic headshot.jpg

Jason Grostic, Grostic Cattle Company in Michigan

The Grostic Family farm began in the early 1900’s by Jason’s Great Grandfather and Great Grandmother as a dairy farm.  It has continued through three more generations.  Through those years the family grew and the torch was handed down to the next generation.  In the early 70’s Jason’s parents bought more land and expanded the farm to where it is today.  After Jason’s father died in a tragic farming accident, Jason’s mother decided it was too difficult to continue the dairy farm.

It was then that Jason stepped up and took the farm in a different direction and started to raise beef cattle and grow row crops to sell as cash crop.  He set up a breeding program and for the next five years the herd grew bigger and bigger each year.  In 2009 Jason expanded the business by getting his license to sell meat to the public.  This avenue started at the local Farmers Market selling packaged meat.  While Jason’s family grew so did his business.  Each year he sold more and more meat, continuing to sell at the farmer market, and directly from the farm selling larger packages like whole and half cows.  He included his wife and children every step of the way.  They would join him every Saturday at the farmers market helping to sell meat as well as help with the chores on the farm.

The State of Michigan said they are going to eliminate the herd and put limited use on the property. The Grostic family has been waiting for six months with no additional answers or information. Jason is currently in a lawsuit with Tribar Manufacturing for the contamination of his land and animals.

Adam Nordell photo.jpgAdam Nordell, Songbird Farm in Maine

Adam Nordell and Johanna Davis own and operate Songbird Farm together on a beautiful hilltop farm in Unity, Maine.
For the last 5 years Songbird Farm has produced vegetables on 4 acres and grains on 15 acres the latter of which are leased from the Sebasticook Regional Land Trust. New plans and dreams are in the works with a shift in production models which will greatly expand upon the grain production side of the farm. If all goes well, in 2021 the couple will have 40 acres of patched together land leases growing grain.

Originally from the coastal town of Round Pond, Johanna grew up playing in the woods and streams and helping with a large family vegetable garden, goats, and chickens. After high school she worked on several farms around the country.
Adam grew up in the hills south of Helena, MT, where he spent his free time hiking, catching frogs and playing bass guitar. He came to college in Maine where he and Johanna met. Adam also worked on several farms and after spending a few years in Montana together the couple moved back to Maine in 2011.

Songbird Farm started in a couple back fields, one in Pemaquid and one in Whitefield in 2011. After that it moved to the beautiful river bottom land in Starks. In 2016 Adam and Johanna moved Songbird Farm to Unity. In 2018 Caleb was born into the family.

In late 2021, they learned that their home farm and primary lease field were licensed for the spreading of bio-solids in the early 1990s, (24 years before they purchased their farm and moved to Unity), resulting in PFAS contamination.

CP_Portrait_202203.jpgMaine Congresswoman Chellie Pingree, District 1

Chellie Pingree became an organic farmer on the small island of North Haven, Maine in the 1970s. After graduating from College of the Atlantic with a degree in human ecology, Chellie sold produce to summer residents and raised sheep for wool, eventually starting a mail-order knitting company that employed ten people in the community.

Chellie was elected to Congress in 2008, becoming the first woman to represent Maine’s 1st Congressional District in Washington. In Congress, Chellie relies on her experience as a certified organic farmer to support the diverse range of American agriculture, including sustainable, organic, and locally focused farming. As a member of the House Agriculture Committee and the House Appropriations Subcommittee on Agriculture, she has been a vocal advocate for food policy reform. Her Local Farms, Food, and Jobs Act was partially incorporated into the 2014 Farm Bill, including programs to support farmers markets, local food producers and help SNAP recipients take better advantage of fresh food at farmers markets. And because of her leadership, the 2018 Farm Bill more than doubled funding for organic research, created the first federal produce prescription program, and established the first federal local food program with permanent funding.

Pingree has pioneered legislation to reduce food waste across the American food system and is the co-founder of the bipartisan Food Recovery Caucus. She’s the author of the Agriculture Resilience Act, comprehensive legislation that sets a bold vision of reaching net-zero greenhouse gas emissions in U.S. agriculture by the year 2040.
