Our Staff


Tammy Depperschmidt

Executive Director
6 Years

Tammy grew up in Putnam County on her parent's farm in Buffalo Valley.  She graduated from both Upperman High School and Tennessee Technological University.  She received her Bachelor's Degree in Secondary Education in 1996.  Tammy served as Education Coordinator for two facility schools for at-risk youth in Colorado, Family Tree, Gemini and Children's Ark.  She also received her Masters Degree from the University of Colorado in Special Education.  Tammy moved to Tennessee from Colorado in August of 2011. "I was challenged daily through the experience of working with inner city youth in Colorado.  Many of these adolescents suffered from gang life, severe abuse, and neglect.  In an instant, a seed was planted deep within my heart and took root.  Little did I know then just how much my life would be impacted by working with these kids for over 14 years and how the Lord would use it in years to come."  

Tammy stepped on as Executive Directer in March of 2012.  "Children are our future. Like us, they need nurturing, guidance, and love to grow into healthy adults who can, in turn, impact the lives of others.  The Lord has blessed me in so many ways.  I do not consider what I have been called to do simply a job.  I am living a dream.  As the children grow stronger, so do we.  The future looks bright for our children.  They live a life that is good because of our Lord and supporters who believe in our ministry.  So grateful to our community who makes Mustard Seed Ranch a place where God's love resides for generations to come."

Daniel & Dusti Brooks

Boys' Houseparents
5 years

Daniel and Dusti have served as house parents since 2013.  Along with their own children, Daniel and Dusti have supported 5 children during their time at MSR.  "As a family, we decided to open our lives to other children in need of love.  We moved to Mustard Seed Ranch in 2013 and accepted the position as houseparents for the second boys' home.  Our first child, Caleb, joined our family in November of 2013.  He is a great big brother and continues to amaze us as he grows in Christ's love.  We have watched God strategically move through our lives He has opened doors we would never have imagined.  He brought our middle son Max, through adversity with such grace.  He has held our oldest son Clay, close to his chest while Mommy and Daddy were pulled in 10 different directions, and given us joy through our youngest and very energetic, Tate.  He has walked with us, and even carried us through days when no one else knew what we were going through."  (Dusti Brooks, Housemother) Daniel and Dusti play a key role in providing for our boys along with other childcare team members. Daniel and Dusti are teaching the boys how to problem solve, cope, and to depend on God through faith in Him.  As a result, the boys are growing both spiritually and emotionally.  We are so honored to have the Brooks in our MSR family.

Originally from central New York, Rachel is a graduate of Liberty University in Lynchburg, Virginia where she earned her degree in psychology, specializing in child and adolescent development. She received much of her initial professional experience in Lenoir, North Carolina where she gained valuable experience living on site in a group home for girls.  She served as a child care worker at the Baptist Children’s Home in North Carolina for five years, learning firsthand what it takes to mentor and develop relationships with children in the group home setting.

Development Director

Cookeville born and bred, Brandon came to Mustard Seed Ranch with a background in Communications after previously serving as the Marketing and Communications Director at the local Chamber of Commerce. His call to ministry for youth is deep, serving as a volunteer YoungLife leader in the Upper Cumberland for 7 years before settling down with his wife, Whitney, and their three red-headed boys. 

"Development, at it's soul, is a discipleship opportunity - inviting people to encounter God through the movement of the ministry. It takes an exceptional amount of support, both financially and spiritually, to provide a bright future for the children here at MSR and I never get tired of advocating for them."

Casey Knight
