Theresa Garbe is in her 27th year at her alma mater, Milligan University, where she has served in  administrative roles in Institutional Advancement and Institutional Research and Effectiveness and as an instructor.  She holds a BA in Humanities and Communications and an MDiv from Emmanuel Christian Seminary.

She grew up in a house filled with music and music lessons, and some of her earliest memories include tagging along with her mother to civic chorale rehearsals. Combined with her husband's natural musical talent, Theresa's love for all kinds of music and the arts in general carried over to her children, each of whom played the horn in marching and concert band and who have continued to pursue various artistic endeavors.   

In addition to serving on the JCSO board, Theresa has served for many years as a lay leader at her church, and she was an active volunteer with City Youth Ballet for more than a decade.

Theresa is married to Jim, and they have three adult children: Chloe, Max, and Mia.

Susan Sterling Lambert received her degrees in Music Education from the University of Tennessee.  Currently, Mrs. Lambert is in her fortieth year as the Director of Orchestras for the Johnson City School System.  During her tenure, her ensembles have consistently received Superior ratings at local, state and national competitions, including: American String Teachers Association, National Honors Orchestra competition, Festival Disney, and Festival of Gold.  Her ensembles have performed with internationally known artist Mark Wood, Christian Howes, and Black Violin. Under her leadership in the Johnson City Schools Orchestra program, student membership has increased 1150% from 32 students to a current enrollment of 400 students.  Along with grade level orchestras at each school, she has created an Indian Trail Intermediate School Fiddle Club Ensemble, Liberty Bell Middle School Electric Ensemble, and a Science Hill High School Chamber Ensemble.  

Mrs. Lambert has served as East Tennessee Band and Orchestra Association Orchestra Chairperson. She is also active in the state level American String Teachers Association.  Mrs. Lambert is a Grammy nominated Music Educator and has received the Outstanding Achievement Honor from American String Teacher Association.  Her professional organizations include American String Teacher Association, East Tennessee Band and Orchestra Association, Tennessee Music Educators Association, and National Association for Music Education. 

Amanda Prunkard has called Johnson City home for over 20 years. She and her husband moved here and got married in 2004 and have loved raising their family in this community ever since. Their son, a proud Johnson City Schools graduate, was deeply involved in the orchestra program from 6th through 12th grade—an experience that sparked Amanda’s long-standing dedication to supporting music education.

​

She began volunteering with the Johnson City Schools Orchestra Guild in 2017 and served as president for eight years. In 2025, she transitioned into a board member role with the Guild and also joined the Johnson City Symphony Orchestra board as treasurer to continue nurturing the arts in the broader community.

​

Amanda works from home doing spreadsheet-based administrative projects for a local automobile dealership. Outside of volunteer work, she and her family love to travel—especially cruising—and try to take several trips each year. She also shares her home with two spoiled Maine Coon cats: “Dobby” the House Elf and “Oliver” Wood.

Theresa Hayes was blessed to grow up in a home where classical music was highly valued and often played. Listening to the live broadcast of the Metropolitan Opera was a frequent treat, while evenings often found the family gathered around the “Hi-fi” listening to carefully chosen and protected LP albums.

​

Since every member of her family was an educator, Theresa at first sought a teaching degree, but after her creative writing professor praised her ability and at the advice of her college advisor, she switched to obtaining a B.A. in English. This led to a 30-year career in the publishing industry, which in turn allowed her to develop public speaking skills when representing Standard Publishing at writers’ conferences across the United States. In addition to editing the work of others, Theresa wrote and published two books and hundreds of free-lance articles.

​

For Theresa, one of the hardest parts about moving from Cincinnati to Johnson City was leaving Cincinnati’s famed Music Hall, but she was delighted to discover that the Johnson City Symphony Orchestra and the many marvelous student and faculty performances at Milligan University and ETSU beautifully satisfies her need for soul-enriching music.

Cherylonda Fitzgerald, a native of Louisville, KY, received her Bachelor of Music in Performance and Music Education from the University of Louisville and her Master of Music in Performance at S.U.N.Y. at Stony Brook. After receiving her degrees, she married, moved to San Francisco and pursued a career in computer graphic design and print production, working for Electronic Arts, HarperCollins Publishers and Gap, Inc. 

In 2003, the Fitzgerald family, including three cats, relocated to the Tri-Cities and Cherylonda’s focus returned to music. She has been with the Johnson City Symphony Orchestra since 2004, and regularly plays with the Asheville Symphony and the Kingsport Symphony of the Mountains. Ms. Fitzgerald is a founding member of The Paramount Chamber Players music ensemble and also plays chamber music with The Johnson City Symphony Trio and others. As a music educator, she is a former adjunct instructor at East TN State University, teaches at Milligan University, maintains a private cello studio, and is co-director of East Tennessee Cello Days, an annual weekend workshop held at Milligan University.

The Fitzgerald family has grown to include five cats! When not herding cats, Cherylonda enjoys biking, hiking and laughing. A love of whitewater kayaking has led her and her husband down the Grand Canyon and to rivers in California, Idaho, Oregon, Mexico, Costa Rica and New Zealand.
