On Problems Solving for Oil Painters, Gregg Writes:
“The book came about because Don Holden—an editor at Watson Guptil—saw a little workshop class description I had written and contacted me to see if I was interested in doing a book. I mentioned to him during our interview that in working with paintings that were weak or flawed or irresolvable, I often found that certain recurring strategies could help get the paintings on track. He asked me if I could make a list of these strategies, which I did, and pretty soon I got myself a big fat contract. I spent the next year trying to flesh out all my ideas into a full fledged book. Watson Guptil was helpful during this process in that they didn’t intrude much and didn’t try very hard to make me include concepts like “Always keep a trash receptacle near your easel.” I didn’t want typical how-to book ideas. I wanted the book as much as possible to be about universal principles, about the essential abstractions that underlie all good art.”

Articles
Kreutz has contributed to many publications, including American Artist and Artist International. Topics range from Cityscape painting to Norman Rockwell.

Plays
In addition to painting, Kreutz is also a playwright. He has written three full length plays that are published by Samuel French—House of Plays. They have been and continue to be performed world wide, and one of them Bottoms Up! has been translated into (of all things) Dutch.

In the summer of 2011, Samuel French published Gregg's latest play, 'Death by Golf'.

In addition, 'Floored' has been published in Smith & Kraus’ anthology,
“The Best 10 Minute Plays of 2006'.

On his playwritting Gregg writes:
“I got into playwriting almost by accident. I was helping out at a community theater in West Virginia—Brookhills Playhouse—and because they loved doing comedies particularily farces, I decided it might be fun to try and write a farce myself. It turned out to be incredibly hard and time consuming but I persevered and after about eight months of intensely examining issues like “if he’s hiding under the bed in this scene how is he going to get into the closet by the next?” I finished it. The theater liked it, put it on, and later, Samuel French decided to publish it. Both Bottoms Up! and Academia Nuts (my second play) are now produced around the country and in other countries too and these days I find it quite a thrill to learn about a production and then sneak off to go see it in person.”
