About Us


The Seymour Agency strives to offer aspiring and established authors the representation they need to succeed in the publishing world. From foreign rights to film rights and everything in between, we provide emotional, professional, promotional, and editorial counsel to each of our authors.




Mary Sue Seymour was listed by Publishers Marketplace as one of the top dealmakers in the country.

Mary Sue founded The Seymour Agency in 1992.

Mary Sue Seymour was a member of the Author's Guild, the AAR, ACFW, WGA, and RWA.

She was named ACFW's AGENT OF THE YEAR in 2015. 

After graduating from the State University of New York, Mary Sue taught in a public school system for almost fifteen years. While teaching, she completed graduate work at The State University of New York. At the same time, she wrote for national publications such as Junior Scholastic, The Artist's Magazine, The American Artist, and teaching magazines.

Mary Sue believed in the Bible verse in Romans 10:12

that states, "For there is no difference between Jew and Gentile - the same Lord is Lord of all and richly blesses all who call on him..."

Mary Sue loved to attend church and sometimes went to the local service at her Protestant church and then later in the day goes to the Contemporary Christian service at nearby St. Lawrence University. She taught Vacation Bible School and also did some work at a local catholic school with their vocal music and art program. Also Mary Sue taught adult watercolor on Wednesday evenings as part of the Continuing Education Program at The State University of New York at Potsdam - her alma mater. A former class room teacher, Mary Sue has also given private piano and art lessons in her home for over 20 years. 

Mary Sue's two sons, Matt and Luke, [named after the gospel writers] are her pride and joy. Matthew, a 2004 graduate of Clarkson University lives and works in Baltimore, MD. Luke attended Canisius College in Buffalo, New York where he played D-1 soccer.

Always in our hearts, her agents carry on her legacy and vision.



Nicole has been listed by Publisher's Marketplace as a top dealmaker in the country, and named ACFW's 2012 Agent of the Year.

She loves discovering new talent and helping established authors to take their career to the next level.

Do you have the next project to feed her book addiction? A smart, tight read she won’t be able to put down? A signature voice she’ll fight to represent?

HEA’s are a must for romance. Mainstream suspense, thrillers, mysteries, YA and inspirational novels are welcome. A consummate science geek and card-carrying Mensa member, Nicole would love to find the next great science fiction/fantasy novel or action/adventure masterpiece.  

Currently on her wish list: high concept middle grade, any kind of romance, and really fresh voices in YA.

Nicole is a member of AAR, ACFW, RWA, and Mensa. She holds degrees in biology, psychology, and behavioral neuroscience. Like Mary Sue, Nicole taught in the public school system and has worn many hats before heeding her calling to become a literary agent--for which she will forever be indebted to Mary Sue Seymour.

 "I have the best job in the world. I read for a living and make author's dreams come true."

Born in Nashville, Tennessee, Elizabeth “Lizzie” Poteet attended Colby College where she majored in English and Religious Studies. While studying at St. Andrews, she realized that though she enjoyed Shakespeare and the Dead Sea Scrolls, she preferred reading stories with a little more heat and heart. Lizzie took her passion for romance and turned it into a position with RT Bookreviews as a romance reviewer. In 2011, she joined the editorial team at St. Martin's Press where she worked with romance, YA, nonfiction, and women’s fiction. Then in 2015, Lizzie became the e-book original coordinator for SMP Swerve, helping launch the digital only romance imprint.


Lizzie is always looking for a good love story. She loves classic romance tropes, strong dialogue, sassy heroines, witty banter, and good old fashion romance. She’s actively seeking inspirational romance, cozy mystery, New Adult, YA, romantic suspense, historical and contemporary romances, and loves anything with a happy ending.


Please no poetry, picture books, or literary fiction novels.



Tina Wainscott is the USA Today bestselling author of over thirty novels with romantic thrills and suspenseful chills. She’s been published with houses such as St. Martin’s Press, Harper Collins, Hachette, and Random House since 1995, so she understands the business from the author’s perspective. As an agent, she’s looking for self-help nonfiction that inspires people to reach for their best and overcome life’s challenges.

A Note from Tina:

As I considered becoming an agent with this amazing agency, I knew what my area of interest would be as soon as Nicole mentioned “self-help” as one of the categories on which they wanted to focus. Though I continue to write fiction, I am also invested in my own soul journey. I love the feeling of reading a book that helps me transform, to see the world through a new perspective, and its challenges in a new light. The idea of helping writers share their vision with others, when it comes from their heart, is thrilling!

I’m looking to work with a select few authors who have an idea that fits into self-help/ personal transformation/spiritual growth but also has that special something to stand out in a crowded market. If you have a provocative idea, a grasp on your platform, and a fabulous title and hook, I’d love to see it!

Please limit queries to self-help/non-fiction books. No memoirs (unless it specifically aims to use your life/experience as a teaching tool), poetry, or children’s books.

Note: Please send religious/Christian queries to Julie Gwinn.

Send your query with clear marketing/platform info, your proposal, and sample chapters (in a Word or PDF doc) to



Jennifer has five years’ experience in some of the publishing industry’s leading literary agencies.  She worked with publishers around the world as an assistant in Trident Media Group’s huge foreign rights department, and with domestic publishers as an assistant at Writers House (where, incidentally, she began her career as an intern).  

She joined the Seymour Agency in April 2016, where she has quickly moved up the ranks to Associate Agent.  Jennifer has always loved helping fledgling authors become NYT bestsellers and she’s ready to be a relentless champion for her own clients’ work.  You can find her @WillsWork4Books  on Twitter.


Jennifer is particularly interested in a wide range of picture books and cookbooks, with a soft spot for author/illustrators of sweet and wacky picture books, and cookbooks with mouth-watering recipes of the health conscious, budget friendly or celebrity chef variety.  For fiction, she’s also interested in middle grade and YA with a sci fi/fantasy, horror/suspense, or contemporary bent, and upmarket women’s fiction with a sense of humor. On the nonfiction side, narrative nonfiction and memoir are also welcome.  If your manuscript has a great hook, a distinct voice, and can make her laugh out loud or ugly cry (or, even better, both), she’d love to see it.


It all started in New York City! 

At RWA 2011, Marisa accepted the position of literary assistant for The Seymour Agency. She judged a contest, loved one of the entries, and encouraged that entrant to query Nicole. She then learned that the same entrant received six agent offers. The rush of discovering new talent was too much to resist. She's never without a book to read, and working with Mary Sue and Nicole is thrilling. 

Marisa has been responsible for spearheading the agency’s efforts to identify, inform, and involve the literary community in outreach and advocacy programs. She will oversee the R&D for both the New York and Florida offices.

Cleveland, who has a Master’s degree in Educational Administration in Organizations, joined the agency in 2011 after she ended an eight-year career teaching students language arts, grades 6-12. Previous to teaching, Cleveland worked as an assistant director for a graduate school in Washington, D.C. before settling in Southwest Florida.

In February 2015, Gulfshore Business and D’Latinos magazines honored Cleveland with the Arts and Culture 2015 FACE Award, celebrating diversity in Southwest Florida. Cleveland was selected as a 2014 “Forty Under Forty” in the September issue of Gulfshore Business magazine. She was honored for her efforts to support literacy. She established the Agency’s literacy fundraiser and supports authors in their writing endeavors with motivational events such as Cupcakes, Cocktails, and Critiques at the Romance Writers of America National Conference. Last fall she taught a workshop on plotting for writers, and she is ridiculously adamant about supporting the cultural and performing arts. She regularly donates critiques, phone chats, and coffee meet-and-greets in auctions and fundraisers through the agency. Her most recent project  included a nationwide fundraiser to support the Literacy Council Gulf Coast.

Marisa is a New York Times and USA Today bestselling author, a Friend of Bayshore and a member of the Florida Literary Coalition, the Naples Press Club, Romance Writers of America, Contemporary Romance Writers, Young Adult RWA, and Southwest Florida Romance Writers.
