coll kosinski – Editor

Picture book author with 10 years experience working with NYC publishers. My passion is picture books. Let me share my knowledge with you!


Hi! My name is Colleen and I'm an author/illustrator. I've been on my journey through the land of publishing for over two decades! During that time, I've worked with the wonderful people at Altair Literary, Stimola Literary Studio, Hummingbird Literary, Creative Authors Ltd, Sky Pony Press, Schiffer Publishing, Two Lions Publishing, Apples and Honey Press, and more! I teach workshops on picture book writing and network with hundreds of agents, authors, and editors daily. I'm very involved in my local chapter of The Society of Children's Book Authors and Illustrators, and The Rutgers University Council on Children's Literature.

I am not only an editor but also a traditionally published author. My titles include LILLA'S SUNFLOWERS, A PROMISE STITCHED IN TIME, A HOME AGAIN, LOVE MADE ME MORE, and LITTLE STAR. My books have been favorably reviewed by Kirkus, School Library Journal, and Publishers Weekly. A HOME AGAIN is available in eight languages!

Let me share what I've learned with you. Over the years, I've worked with many authors. I know critiques are sometimes hard. Your book is your baby. But I will handle with care. Nothing gives me more pleasure than to hold a book in my hands whose author's words I helped shape.

- Dawn Young (author of NIGHT BAAFORE CHRISTMAS and COUNTING ELEPHANTS) : Colleen inspires you to become a better writer through her encouraging words, literary prowess and pure artistry. You can count on Colleen to strengthen the heart of the story and make your readers connect. She has a keen sense for rhythm and sound which certainly helps with pacing, flow and word choice. Colleen will ask questions that make you think about the theme, arc and thread of your story. Whether your story needs tweaking, a complete overhaul, or a stronger sense of heart you can trust Colleen to help your story shine.

I was highly impressed by Coll's professionalism, attitude, and creative insights. As a screenwriter and story consultant, I know the best feedback is honest and straightforward. It should be focused on helping the writer get on track to tell the best version of their story. And that's what Coll did. She also went above and beyond with her follow-up, allowing me to ask questions to better under...

Very limited amount of time was provided. She appears to be knowledgeable but conversation for me, was labored and awkward. This may not be the case for others.

Sorry you felt that way, Deb. I thought we had a very good conversation and I was willing to stay on the phone and answer as many questions as you wanted to ask. I also rewrote your entire manuscri...

Coll's help has been invaluable. Not only did she quickly identify what was off in my story and provide excellent recommendations to fix it, but she also offered helpful tips for preparing for traditional publishing. All of this, and she stayed within her quoted timeline. I'm incredibly grateful for her expertise, and I must say, I'm so happy to have found her here. She's knowledgeable and also...
