Management & Artistic Staff

 C. Douglas McCarroll is returning for his third season, but in his new role as Executive Director of the San Antonio Choral Society (SACS). Doug’s passion for the performing arts, breadth of experience and his selfless dedication to the mission and well-being of SACS and it members made him the logical choice to lead business operations for our growing organization. Born and raised in Steubenville, OH, Doug is a graduate of Wintersville High School and attended the Ohio State University receiving his degree in Industrial Engineering specializing in Healthcare Management. He received his culinary accreditation from the Culinary Institute of America.

Mr. McCarroll’s experience with Performing Arts and Nonprofit Management spans almost 30 years. He has performed in the Wintersville High School drumline, color guard, and symphonic sand, a jazz choir (Tenor) and Ohio State Band on cymbals. Professional credits include two seasons at Kings Island as a singer/principal dancer and show host. He has performed with the Bluecoats and Cavaliers Drum & Bugle Corps color guards, Generis Independent Open Winter Guard and Revolution Independent World Winter Guard. He continued on as an instructor and administrator for many of today’s world class Drum Corps International (DCI) and Winter Guard International (WGI) units allowing him to pass on what he had learned through his years as a performer. He has been actively involved in the “Sport of the Arts” for 29 years serving in various educational and nonprofit management capacities such as a visual tech, color guard tech, recruiting and tour management. The culmination of his experiences led to his appointment as Director of DCI Div III World Champions Revolution Drum & Bugle Corps (2000-2002).

As a member of the United States Air Force, Doug served as a Linguist, Nutritionist, General’s Aide, Dining Facility Manager, Business Analyst, and Process Engineering Program Manager. Doug did not lose touch with his love of performing while serving our country as he performed as a dancer, competing in talent shows all over the world, mission permitting. The culmination of his performing experience and service to our country won him the opportunity to serve as Lead in the elite Air Force Tops in Blue (1989), filling the roles of show MC, principal dancer, and chorus member. After retiring from military service, he worked as a Management Consultant for the San Antonio Military Medical Center, Baptist Health System, WellMed Health Services, Booz-Allen Hamilton, Global Resources, and the Institute of Surgical Research.

He has since retired from the engineering field to pursue his love of culinary arts and other entrepreneurial opportunities as owner of Doug’s Comfort Cooking Catering Service, Executive Chef, Diesel Body Shop (Diesel Foods Inc.) and columnist for “The Worldwide 411 News” Magazine. In his spare time, Doug continues to support the performing arts as Director of Fundraising for Identity Independent World Winter Guard and Nutrition Consultant for the Crossmen Drum & Bugle Corps. Doug currently resides in San Antonio with his partner and has been blessed with 2 children and 4 grandchildren.


Dr. Jennifer L. Seighman is in her fifth season as Artistic Director of the San Antonio Choral Society. Her extensive experience in choral pedagogy, passion for choral performance and unmatched ability to inspire and revitalize the aspirations for excellence, in even our most seasoned choristers, continues to reaffirm her appointment as Artistic Director in 2011.   Since then, Dr. Seighman has worked to raise the level of vocalism in singers through her ability to diagnose vocal/musical issues and engage the singers in strategies that build vocal and aural skills. Her ability to work effectively with singers of all age groups as well as amateur and professional musicians alike has been an asset in stretching the choir to reach higher levels of musical achievement and new challenges in regards to performance practice and style. Her facility in working with both vocalists and instrumentalists has proved a valuable asset as the choir performs a substantial amount of works from the choral-orchestral repertory, as is the case this year.Under her baton, collaborative performances have included a multiple choir and brass Gabrieli celebration, the SA Symphony Brahms Festival, Britten’s St. Nicolas, Orff’s Carmina Burana at the new Tobin Center for the Performing Arts, and an historic ten-day choir tour to Bavaria and Austria.  Over the past twenty years, she has worked professionally as Director of Music and Organist, building sacred choral music programs in various churches and has taught choral music in both public and private school settings. 

Dr. Seighman graduated magna cum laude with the Bachelor of Music Education degree from  Westminster Choir College where she studied voice and organ and sang with renowned orchestras including the New York Philharmonic, the NJ Symphony, and the Philadelphia Orchestra. She received a Master of Music degree in Choral Conducting from the University of Oklahoma and a Doctorate of Musical Arts in Sacred Choral Music from the Catholic University of America.  The focus of her doctoral research was a multi-case study of Catholic choir school programs in the United States, which she recently presented at the Psallite Domino liturgical music conference in Liverpool, England.

 Dr. Seighman has received awards for sacred music, music education and organ. She has been the recipient of three awards from the National Pastoral Musicians for her contributions in the field of sacred music. In addition to her current position as organist at Travis Park United Methodist Church in downtown San Antonio, she has been organist for Brahms’ Ein deutsches Requiem with the San Antonio Symphony in 2011 and the Texas Choral Directors Association annual conference worship service in 2013. From 2012 to 2014, she presided as Dean of the Alamo Chapter of the American Guild of Organists.  Dr. Seighman frequently serves as guest conductor, clinician and adjudicator. She enjoys collaborating in churches, schools and communities with musicians of all ages. Jennifer resides in San Antonio with her husband, Gary, Director of Choral Activities at Trinity University, and infant son Justin.


Dr. N. Seth Nelson, Accompanist, earned his DMA and MM in organ performance from The University of Michigan under the tutelage of Dr. Marilyn Mason. While there, Dr. Nelson was also the first to earn the Certificate in Musicology, writing a thesis on the pipe organ controversy of the Puritans in New England. He earned a BM from the University of Texas at San Antonio as a pupil of Dr. Bess Hieronymus. There he received numerous awards for his work as an organist, pianist, and accompanist, and was honored with the Presser Award, graduating from the UTSA Honors College Summa Cum Laude.

A passionate church musician, Dr. Nelson is Organist at the 150-year old First Baptist Church of San Antonio. Previously, he has been Organist at Redeemer Presbyterian Church in Austin, Texas, and Shepherd of the Lakes Lutheran Church in Brighton, Michigan. Dr. Nelson, an Associate with the American Guild of Organists, maintains an active concert schedule and has performed in France, the Czech Republic, Poland, England, and throughout the United States. Equally comfortable on the piano as the organ, he is in high demand as a collaborative musician.
