Rev. Shannon Sullivan

Senior Pastor

Pastor Shannon is  a life-long United Methodist and second generation clergywoman. She experienced the love of God through Sunday school teachers, in Vacation Bible School, and on mission trips to Bosnia and Herzegovina as a teenager. She took over teaching parts of VBS as a middle schooler, and her mom said she knew she had a call to ministry then but she didn’t! Pastor Shannon went to college thinking she would become a missionary, that would serve God in some way working for social justice or in caring or teaching ministries. She wanted a job like her mom’s, but she never wanted to be a pastor! Pastor Shannon had her first faith crisis in college when life did not go as planned, and emerging from that hurt is when she first heard her call to ministry.


Pastor Shannon was twenty when she heard the call in Washington, DC, at a worship service curated by the Methodist Students for an All-Inclusive Church (MoSAIC). A pastor friend was serving communion, and, when she took the bread and broke it, it was rainbow challah bread. After a season of feeling adrift, like God had left her to fend for herself, in that moment she felt as though God was pointing and saying, ‘Here. This is where you are supposed to be. This is what you are supposed to be doing.” At that moment she felt like she belonged; she felt that this was home. It was a feeling of completeness that she wish for everyone. And it is a feeling that is not accessible to everyone in the church. She knew in that moment God was calling her to preside over the table to invite ALL people to the feast. A table abundantly full of God’s nourishment and chairs filled with hungry people of all shapes and sizes, all backgrounds. A table of abundant love.


Pastor Shannon shares the following:

A call is not a once and done thing, just as discipleship is not something that happens at one point and you never have to work for it again. My call continues to evolve and change but that abundance remains. I am coming to you after being an associate for four years, but I was a solo pastor five years before that and a student chaplain in a behavioral health unity before that. At Calvary, I feel like much of what I have done has been survive the pandemic and learn how to edit videos and run Zoom studies, but in the years before the pandemic I focused on ministry with young people from running Vacation Bible Schools to leading youth groups to working with the young adult group Pastor Suzanne started when she was here. I led Bible studies and co-led retreats, which were also great blessings to me in my time at Calvary. I served at Presbury United Methodist Church in Edgewood, Maryland, for four years before that. There, I expanded the church’s programming with children and youth and strengthened the church’s mission participation through local and national partnerships. I also served on the steering committee that re-established the Emergency Rotating Shelter (ERS) in Harford County to provide shelter for those experiencing homelessness, and Presbury was the first host congregation of this effort. My first appointment was for only a year after I graduated from seminary: Deer Creek and Mt. Tabor United Methodist Churches, two small rural congregations in Forest Hill and Bel Air. There I focused mainly on pastoral care and ministry with children. As a seminarian, I served in a variety of settings, including as chaplain in the behavioral health unit of a New Jersey hospital, an experience I built upon as a volunteer hospital chaplain in Harford County as well.


I also have experience in community organizing, creative worship design, international missions, and non-profit work in communications and mentoring. I have traveled extensively through educational and research opportunities in Bosnia, France, Venezuela, Mexico, and Ghana, and have done mission work in Appalachia, Bosnia, South Africa, and Haiti.


Where I find abundance in my life most now, though, is in raising children. I do a little of that as a pastor and an aunt (I have three nephews), but a lot as a mom. We have one living child after three losses and many failed fertility treatments. His name is James Ezekiel- we call him Zeke. He is nineteen months old and always on the move. He doesn’t talk much, but he loves making noise by playing instruments! He loves animals. He brings us so much joy! Now, motherhood is hard and frustrating- I don’t want to overly glorify it! But seeing the world through the eyes of a child day in and out is such a blessing.


I parent with my wonderful spouse Aaron Harrington. We have been together since high school and still kinda like each other! He is a pilot for a charter jet company, and he loves all things airplanes. He used to be an aerospace engineer, he is restoring a 1940s airplane (I helped ribstitch!), and he has his helicopter license too. He is also the chief flight instructor at Frederick Flight Center. He is currently teaching himself to play the banjo to prove he has other interests besides airplanes. We love traveling together, whether or not Aaron is flying us there, and exploring Frederick. He fills my life with abundant love and has abundant patience with me when I am weird. Which happens on occasion (or maybe all the time, but I’ll let you find that out). We have a dog named Stella, two cats, and six chickens, all of whom feature prominently in our adventures as well.

Pam Hewetson
Counselor, Trinity Pastoral
Counseling Center

Pam Hewetson is from Philadelphia, Pennsylvania and completed her B.A. in History there at the University of Pennsylvania.  She also earned a M.S. in Pastoral Counseling from Loyola University followed by a Certificate of Advanced Studies in Pastoral Counseling.  As a Licensed Clinical Professional Counselor Pam serves as the director of the Trinity Pastoral Counseling Center.  She shares the following…

One of the reasons that I am involved in the counseling ministry at Trinity Pastoral Counseling Center is highlighted in the following verse… “The Lord God is my strength, And He has made my feet like hinds’ feet, And makes me walk on my high places.” Habakkuk:3:19

The meaning of this verse for me is that we rely on God and that as we do that we grow toward wholeness and can then companion with others as they do the same.

The hind is a female deer that can climb to greater heights than any other deer because its back feet track exactly where its front feet have been thus making it very surefooted.. This is one image of integrity or wholeness which occurs when all aspects of who we are are in sync and are working well together.

The “high place” we come to, for me personally, is a ministry that in particular supports others in their growth toward wholeness.

The following is one reason why the counseling ministry is important to Trinity United Methodist Church.

After Jesus raised Lazarus from the dead “He said to them, “Unbind him, and let him go.” John 11:44.

Providing counseling to the congregation and to the community is one of the ministries at TUMC that hopes to participate in the unbinding of people from that which prevents them from living a more abundant life.

Wendy Huff
Passionate Youth Minister,
Christ follower, mother of three teenagers, singer, dancer,
music fanatic, story teller,
and beach comber

Wendy grew up in the United Methodist Church, quite literally.  Her father was a United Methodist minister for 20 years, and her grandfather became a local pastor after he retired from the business world.  Wendy enjoyed growing up as a “PK” or preacher’s kid.  Mischief aside, she found that growing up in the ministry provided her an opportunity to meet many new people and to build relationships in faith communities throughout the Baltimore Washington Conference.

Wendy has been working with youth for many years.  She has been teaching dance for more than 30 years, and became the youth minister for a United Methodist church in Poolesville in 2010. She served as youth minister for 5 1/2 years, and in the fall of 2015, graduated from Princeton Theological Seminary’s Youth Ministry and Theology Certification Program.  In the summer of 2014, she also took on the job as the Admissions Coordinator at Franklin Montessori Schools. 

Many words can be used to describe Wendy: creative, outgoing, friendly, leader, kind, team player, encourager, funny, talkative, caring, and honest.  Her gifts: creativity, teaching, compassion, organization, leadership, and a sense of humor.  Most of all she has a love for Christ, a love for youth of all races, nationalities or backgrounds.
