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, 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, and LOVE MADE ME MORE. My books have been favorable reviewed by Kirkus, School Library Journal, and Publishers Weekly. A HOME AGAIN will be available in seven 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 would definitely hire Coll again. As writers we can tell our story is missing something and after having other writers critique my manuscript I realized that I needed a professional. She delivered a comprehensive developmental edit within timeline she quoted. Her notes and suggestions were clear and gave my story the direction about ending I knew was missing but couldn't quite envision. I ...

Colleen is an excellent editor. She provides fantastic, timely, and thoughtful feedback, and has an amazing depth of knowledge about the traditional publishing environment in the US and Canada. She is easy to talk to and wonderful to work with. My book is far better from her thought-provoking questions, and I feel much more confident moving toward agent representation and publication. I highly ...
