The Seymour Agency strives to offer aspiring and established authors the representation they need to thrive 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 is listed by Publishers Marketplace as one of the top dealmakers in the country. Mary Sue founded The Seymour Agency in 1992.

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

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 is a Christian but believes 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 loves to attend church and sometimes goes 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 teaches Vacation Bible School at her church and also does some work at a local catholic school with their vocal music and art program. Also Mary Sue teaches 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. She loves to be busy and is working just about all the time. When Mary Sue stands before God someday, she hopes she can tell him that she took each and every talent God gave her and used them up so that there is no more left.

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. She goes there to see him any chance she gets and is becoming a real Oriole baseball fan. Luke attends Canisius College in Buffalo, New York where he plays D-1 soccer. He is a goal keeper and is majoring in communications. He attended Avon Old Farms in CT on a scholarship to be their goal keeper.


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 shewon’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."

JULIE GWINN -- Associate Agent

Last year she was awarded Editor of the Year from the American Christian Fiction Writers and won B&H’s first Christy award for Ginny Yttrup’s debut novel Words. She has more than 25 years public relations and marketing experience and has also worked in marketing for several Nashville non-profit organizations including the TN Assoc. for the Education of Young Children, the Nashville Area Red Cross and the YWCA.

LANE HEYMONT - Associate Agent 

Serving as a Literary Assistant for the past two years at the Seymour Agency, Lane Heymont has led the marketing efforts for their authors and enjoyed connecting clients with readers. As a lover of literature since childhood, he decided to pursue his passion as a literary agent to bring more well written books to the masses. 
With a bachelor's degree in Psychology, business and literature, Lane continued his education in Creative Writing and English, attending Harvard. 
Lane is hungry for well-written science fiction and fantasy novels. Exceptional world building is a must. In the non-fiction, he is looking for the inspiring, intriguing, and mysterious.  
Lane is a member of HWA, ITW, and AAR. He believes what John Gregory Dunne said: “Writing is manual labor of the mind.”

A PERSONAL NOTE: Hi, all! Lane Heymont here, new to agenting, but not to the industry. I am looking to represent a select few authors in fantasy, science fiction, romance, nonfiction and Judaica. 
As a child, I read most the classics of literature, mostly due to my grandfather’s insistence. However, my heart always belonged to fantasy, weird, and science fiction. Most of my fantasy selections included Margaret Weis, Tracy Hickman, James Lowder, R.A. Salvatore, Robert Jordan. You might have guessed I was big into Advanced Dungeons and Dragons, and I was.
As for science fiction? I leaned toward the hard and subtle. Little green aliens shooting death rays don’t work for me. Try Who Goes There? by John W. Campbell Jr. (the inspiration for the 1982 movie The Thing). Others include Isaac Asimov, Carl Sagan, and weird horror/science fiction in the veins of H.P. Lovecraft. Without the overt racism.
What exactly am I looking for? Well, my all time favorite novel is Frankenstein, or the Modern Prometheus by Mary Shelley. It’s everything, Gothic horror, science fiction, and a dash of the weird unknown and possesses what makes these genres great.
In fantasy, I’m open to most genres. High, urban, contemporary, or magical realism, but I love it dark, gritty, and believable. That might sound strange, but how would you react to seeing a monster in real life? I have no interest in the perfect heroine or hero. We all have problems and I want to see them play out just as much as the dragon breathing flames everywhere. Also, English medieval societies have gone stale for me. Medieval times are great, but I’d like to see some different (read: multicultural) types of societies. Perhaps a fantasy based on tribal Africa. Or Native American. A Polish culture? These, without any marginalization of said culture, would be great!
In science fiction, I’d love to discover the next great weird, otherworldly novel. Keep it hard or mysterious. Think Carl Sagan’s Contact, Frankenstein, or H.P Lovecraft.
I look forward to seeing everyone’s submissions and if you have any questions, feel free to connect with me on Twitter. You’ll see I’m very active! 

MARISA CLEVELAND - Executive Director of R & D

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.
