Traci Rostamo:

 I am the oldest of 6 kids, and I live in my hometown of Owasso, OK.  I attended college in Rockford, IL, have a bachelor’s degree in Accounting with a minor in business, and hold a CPA license.  I have practiced public accounting in a medium firm, had my own business for 9 years, and work part time for a non-profit conservation organization in Tulsa.  My kids and I attend Rejoice Church in Owasso and I facilitate the Soul Care satellite class established Fall of 2014.   

After 13 years of marriage and 18 years together, my children’s father and I recently divorced when a crisis with his addiction and my struggle breaking free from co-dependency came to a head.  To say I never thought that I would divorce is an understatement, but I know God is working so much good through it, even though it feels horrible sometimes. We do have 3 great kids from our union and for that I will be forever grateful.

God led me to Plumbline through crisis in my marriage 6 years prior to my divorce, but I would soon learn there was much more I needed help with and had been blind to.  There was so much heresy in how I viewed God and so many lies I believed about myself and my situation.  God started revealing himself to me through the most intense, sad, and toughest times of my life and continues to do so now.  Through the people God put around me to speak truth into my life and through really starting to study Gods word with a fresh set of eyes, I started to taste the freedom of being who God had created me to be!  How good it is to be set free!  Much of my emotional, relational, and spiritual healing has happened as a result of being able to be heard and guided in counseling sessions and classes here at Plumbline.  I love these teachers and comforters of the soul, dearly.  As I learn more and more from them on how to relate better to others and myself, and to allow God to love me as only He can, I am becoming transformed.

  I feel so privileged to be an intern at Plumbline Ministries.  I love God, I love people and I want to give them a little bit of what I’ve received from God.   To comfort in the way I’ve been comforted, to give hope in the way I’ve been given hope, and to be a vessel for God’s good work is simply amazing!   After all, it only seems fitting in light of all God has done for me.  He has lit a fire in me that cannot be extinguished and my only hope is that a little part of my story will catch someone else on fire in all the right, painful, beautiful ways. 

The light shines in the darkness, and the darkness has not overcome it. (John 1:5 NIV)

Eileen Hobbs:

Eileen was born and raised in Connecticut with her mom, dad, older sister and younger brother. After high school she decided to go to Oklahoma and study physical education at Oral Roberts University. After one year of college and no planning she married and had three daughters within four years. Life became very difficult and she had to grow up right along side her children.
Eventually her and her husband divorced. Eileen went back to school and this time studied psychology because of all the difficulties she went through. She also remarried to a wonderful man.
While attending school she met Sue Merrill who is a counselor at Plumbline and Sue told her about Plumbline Ministries. Eileen believed that was an answer to prayer. She signed up for classes and would say to anyone that Plumbline is an awesome place to learn, grow and help others!

     Interns are a very important part of Plumbline Ministries.  In short, we trade them extra training (every Mon. morning) and allow them to sit in on our counseling appointments for the benefits of their services in managing the Plumbline office and programs.  The long-term hope is that they would complete 250 hours or more of counseling sessions and then move on to offer counseling on their own, through their church, or (best yet) join the counseling staff here.

     After a participant in our Soul-Care training program has completed two semesters they can apply for internship.  We will already know them pretty well by then and have a good idea about their gifts and calling.  The application includes recommendation letters from their pastors, and support letters from their friends and family.  Once accepted into the intern program, they are supervised by Carol McNamara, befriended by the staff, incorporated into our other programs and PUT TO WORK (as their schedule allows). 

      Internship is divided into two phases. Phase I internship lasts no less than one year. It is during this phase that interns complete the 250 hours of observation with established counselors mentioned earlier. Once it is agreed upon by the intern and the counseling staff that there is a readiness to enter into the next level of preparation to counsel with Plumbline*, the intern begins Phase II Internship. Phase II Internship is independent counseling with mentor supervision (weekly meetings) and will last one more year passed the Phase I year. The intern may or may not continue sitting in with established counselor but will also pick up two to three counselees. It is also during this phase that the intern counselor will face the difficult decision and challenge of whether or not to begin fund-raising. We can offer counseling for free because our sponsoring churches pay the over-head for the ministry and our staff raise their own support; missionary style. SOOO, if one of Phase II Intern Counselors asks you for your financial support please know that they are being thoroughly trained, vetted, and already functioning in important roles here! Yes, our current interns are essential to what we do now and may become the very future of Plumbline Ministries.
