Garret Southerland - Bass​​

Music has always been a major part of my life, particularly Southern Gospel music. When I was a young child I can remember my dad going to the Christian bookstore and buying all of the latest quartet cassettes. I’ve listened to many styles of music “but there is none so dear as when I hear an old convention song.” I originally sang with HHQ as a baritone, and I am now fortunate to be able to return to them singing bass. It is an honor to be able to worship God in four part harmony with my friends. 
I have been married to Courtney Southerland for 6 years and we have two children, Colton and Aubree. Courtney and I graduated from the University of Central Arkansas with education degrees. We now live in Emerson, AR where I coach basketball, tennis, and track, teach social studies, and Courtney teaches fourth grade. 

About Us

Tom Hollman - Lead


I was privileged to be one of the founding members of Hallelujah Harmony Quartet in 2005. Being invited to sing with Hallelujah Harmony Quartet was a lifelong dream come true for me. I had been singing and leading worship in church for years, but I always thought God had something else for me. When I was invited to sing with the quartet I knew it was the opportunity to use the voice God blessed me with to bring Him praise and glory. It was also a great chance to show Christ to as many people as possible. It has been a wonderful ride so far, and I am looking forward to many more years in the future.  


Zach Simmons - Tenor


Growing up in a home where Gospel music was prevalent, I have always had a passion for that old time four part harmony. My father was a quartet singer and is a music pastor, and my mother is a gifted pianist. My passion for music grew as I played the saxophone through high school and college. I was a member of the band at Arkansas State University where I studied to be a physical therapist and my wife, Katie, studied to be a teacher. We live in Cabot, Arkansas with our border collie, Louie, and we are active members at Faith Missionary Baptist Church. I joined HHQ in May of 2020, and I am excited about this opportunity to proclaim the Word of God through worship with this wonderful group

Jackie Moore - Baritone


I have been a lifelong member of Concord United Methodist Church and have always had a love for music. My mom played piano at church, and at a young age, I began singing in a trio with my sister and cousin. I sang in the men's choir and on occasion filled in as song leader. After retiring from AT&T, three friends and I formed a quartet. I was blessed with an opportunity to join HHQ in January 2015. There is nothing better than sharing GOD through song and seeing the smiles on the faces of the people. It has been a great blessing. My wife Donna and I make our home in Lonoke where we raised three daughters and now enjoy spoiling our three grandchildren.  God has certainly blessed me with the love of music and with the many blessings brought to me by my family and church family.
