Martin Wolf 
Founder & President

Martin’s dreams of sharing his family’s farm with the community has been held near to his heart for many years.  Since 1908, generations before Martin understood and carried out the value of being a good steward - not only of the land, but of those within their reach and beyond. 


As career dairy farmers, Martin and his wife, Lucille, raised their family on the farm, managed and operated a successful Holstein dairy, along with serving their community through local township roles, volunteer fire department, being long-term 4-H leaders and actively involved as church leaders. 


The term "retirement” is not synonymous with life on the farm for Martin, as he stays busy with a multitude of projects, field work, fixing machinery and daily gathering of farm-fresh eggs. He currently volunteers for the State of Wisconsin Ombudsman program, dedicated to individuals in nursing home care centers. Martin considers himself a humble visionary, story teller, and lover of nature.  He enjoys sharing God’s blessings with those around him. 


As a father of six, grandfather and great-grandfather, he enjoys spending time with family and enjoying God’s nature.


Beth Zarnke                       Doug Zarnke

Executive Director & Founder                    Founder & Director

From a young girl, Beth loved everything related to horses.  It wasn’t uncommon to find her in the pasture dreaming of how horses could bring peace, confidence and healing to others. 


As a young adult, Beth viewed a TV documentary of a couple who used their hobby farm to bring healing and encouragement to troubled youth. God birthed a vision at that time, however it wasn't until 2016, as she visited Crystal Peaks Youth Ranch (CPYR) in Bend, OR that this vision was refueled.


With a desire to serve her community, Beth currently serves as outreach pastor at a local church, with experience in community and volunteer relations, facilitating small groups, and women’s ministry.  Beth has an undergraduate degree in Business, and worked for 14 years in the Human Resources field. In 2017, Beth received her certification as a Practitioner for Equine Assisted Learning, an experiential learning approach which promotes development of life and team building skills using horses as teachers. Beth is passionate about seeing individuals on the fringe be brought into a place of belonging.  She enjoys bluegrass music, and observing God’s wonder through animals and nature.


Doug’s career as a semi-truck driver for a local food and dairy distributor keeps him busy during the day.  After work he can be found on the farm busy in the fields and keeping the property in great shape for our guests. Doug enjoys serving at church, men’s Bible Studies, nature, hunting, and fishing. 


Beth and Doug love spending family time with their two adult children, their spouse and three grandchildren enjoying nature, farm animals, and enjoying making lasting memories.

Heidi Boe
Prayer Team Leader

Heidi is a true Wisconsin girl, born and raised (mostly) right here in Marshfield!  She loves the outdoors, taking long walks, capturing God's amazing creation on camera, cheering on the Packers and most of all, spending time with her husband, Shane and son, Jordan.  A highlight of their time together is an annual fishing trip to Canada.   


Heidi is passionate about her relationship with Jesus and encourages others to live out their destinies as designed by God.  She finds joy knowing we all have a story to tell and adores how Jesus loves us all the same, yet is so uniquely involved in each of our lives.  


According to Heidi,  she would not be where she is today, or who she is today if it weren't for the power of prayer.  To her, prayer brings glory to God and has untold benefits for those who pray as well as for those who are prayed for.  Something miraculous happens when we pray.  It can improve our circumstances and more critically, can transform us to be more like Him.   Heidi’s favorite quote is "Once we learn to pray with our hearts, and not our lips; we truly begin to have a conversation with God."
