THE SEYMOUR AGENCY - Making Your Literary Dream a Reality


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! Diversity is welcome!
Please limit queries to self-help/non-fiction books. No memoirs (unless it specifically aims to use your life/experience as a teaching tool or you are someone of note), poetry, or children’s books, and please, no fiction. Even spiritual fiction.
Note: Please send religious/Christian queries to Julie Gwinn.

Send your query that includes your book’s blurb, what the book targets, clear marketing/platform info (eg. your numbers as far as followers go, subscribers, professional connections, etc.), 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.

Ever since Jessie was a little girl she was obsessed with stories. She acted out her favorite movies with friends, wrote her own epics in high school, and loved talking shop with any author she could get her hands on. As a 2017 honors graduate from Taylor University, with a degree in Professional Writing, Jessie’s eyes were opened to the dream job while learning about literary agents in college. Through a practicum with Julie Gwinn, Jessie was taken on as an Associate Agent for The Seymour Agency in Winter of 2017.
Jessie is constantly on the lookout for a fresh voice, strong pacing, detailed world building, and unique main characters. She is interested in acquiring YA and New Adult fantasy, as well as contemporary romance, romantic suspense, romantic comedy, a brain twister (think Inception or Black Mirror), and is a sucker for military novels, especially anything to do with long separations or reunions. Jessie is not interested in erotica or heavy fact laden historical romances, but will be on board if it’s anything like Poldark.
As the wife of an Active Duty Airman and slave to her own creative mind, Jessie’s days are full of variety, knitting, and tea drinking.

Her love of books led her to a career in publishing, where she gained a variety of experience working at Skyhorse Publishing, first as a Sales and Marketing Assistant before transferring into editorial at Sky Pony Press. She’s thrilled to be with The Seymour Agency as an Associate Agent. 

          Kat is looking for fresh, new stories particularly from marginalized voices. She’s actively seeking YA of all genres, Adult SFF, Romance of, and select nonfiction. In YA, she’s looking for twisty dark tales with compelling protagonists and in SFF she’s looking for vibrant worlds that draw from traditionally underrepresented cultures. A HEA is a must for all romances. In nonfiction, she is looking for cookbooks and coffee table and gift books.
