As part of the collective at Angelella Editorial, I offer several editing services and work in almost all genres. In addition to writing hundreds of articles and two reference books, I’ve worked my whole career as a proofreader and editor. Over the past few years, I’ve worked on everything from rhyming picture books to adult novels.
Short-Form Critiques
If you’re a beginning writer, you might want a short-form critique. I’ll review your picture book or first chapter, evaluate the potential of your story, identify strengths and places for improvement, offer tips for rewriting, and suggest where it might fit in the market. If you’re lost in the weeds of your novel, I can do an assessment of your detailed synopsis, where I look at which story elements are working, which ones might be improved, and how you might revise.
Query Reviews and First Chapter Editing
If you’re ready to start submitting to agents and editors, I can help with your query and/or synopsis and make sure your first chapter is polished.
Copy Editing and Proofreading
If you’re self-publishing your work, I can proofread or copyedit, where I fix grammar, fact-check, and point out continuity errors.

Client Testimonials
I am relatively new to picture book writing and cannot express how invaluable Diane Telgen has been in my journey. Diane’s gift for teaching, both in conversation and written form, has empowered me to make significant improvements to a picture book verse manuscript. Her encouragement and guidance were instrumental in receiving an offer of agent representation. I am incredibly grateful to Diane for openly sharing her knowledge and experience with me.
Karol Hernandez
I am a member of SCBWI and have submitted work to editors and agents who were guest speakers. I’ve received excellent feedback from most, but Diane’s feedback regarding story-line, character development, scene, conflict, language, and arc is always constructive (both positive and negative), well-thought-out, useful, and intelligent. Diane doesn’t just tell me this works/that doesn’t work, she shows me why it doesn’t work and makes suggestions, i.e., ‘plants the seeds’ so I am able to further grow and develop my story.
