Amy Peters


Amy is a passionate member to the Tin Man team. After graduating high school, she completed two years of training through 24-7 Leadership Academy. She attended Wayland Baptist University to pursue a degree in Christian Ministry. When Amy married Joel, her focus changed to becoming a wife and mother for the next eight years. During that time she created and led a women's ministry called Beloved. 

With a deep heart for women's ministry, Amy’s personal journey has sparked her passion for Tin Man Ministries. Through painful circumstances in her own life, Amy was introduced to Voice of the Heart. As she continues to walk through and live out her own recovery, she desires to walk with other women as they do the same.

When Amy is not meeting with other women, she is a full-time homemaker and mother of Elizabeth and Jeriah. As a family, they especially enjoy camping and exploring the outdoors.


Joel Peters


Joel worked as a professional in the field of engineering for over 13 years. During that time, he discovered a passion for thinking outside the box and working with teams of people to bring solutions to the industrial world. Joel eventually realized a deeper passion to help others, using similar tools, in their path to emotion health and restoration. He has a Master’s certificate from Multnomah Seminary and a bachelor's of Science degree from LeTourneau University.

At an early age, Joel learned how to isolate and hide his heart which led to depression and addictive behaviors. In finding freedom through recovery, Joel is passionate to help other men find the same thing. He is pursuing professional certification in recovery coaching and has benefited from the SRS training provided by the Sage Hill Institute.

Joel and his wife, Amy, recently moved to Nashville to work with Tin Man. They have visited over 16 national parks, enjoy hiking, finding great places to eat and exploring new place. Someday Joel plans to ride motorcycles again…when the time is right!

Sarah attended Auburn University and received an undergraduate degree in Human Development and Family Studies. Once she graduated, she worked on staff at Legacy School of Discipleship, a training program in Alabama for college students. Afterwards, she moved to Nashville to get her Master’s in Marriage and Family Therapy, and has been practicing ever since.  

Sarah enjoys having people over— mostly on her back porch! And though she left the city of Auburn, she will never leave behind her love for the Auburn Tigers... War Eagle!

Sarah Lawrence Allen


Sarah Lawrence has experience in both ministry and clinical settings and currently sees clients for individual, couples, and group therapy as a therapist at Sage Hill Counseling in Memphis, Tennessee.  She completed training in The Spiritual Root System through Sage Hill Counseling in 2015, and it began a journey of recovery that has continued to present.  She is passionate about sharing her experience, strength, and hope from her own journey in recovery and delights in watching others recover their true selves.  

One of her favorite worship bands is United Pursuit, and they capture Sarah Lawrence’s heart in their song, Head to the Heart, “From the head to the heart you take me on a journey, of letting go and getting lost in you.  My heart is open wide; I will receive your light.  You give me faith like a child, in your my heart runs wide.  More than words, more than good ideas, I found your love in the open field.” Nature, outdoors, and play have been places where Sarah Lawrence has experienced both freedom to be herself and healing through God’s presence, love, and delight. She desires to create space for others to experience the same.

Sarah Lawrence is excited about joining you in the journey of recovering your heart as you connect more deeply with yourself, others, God, and creation.
