Our Designer

Karen Kratz-Miller is the founder and artist/owner of BROAD SPECTRUM, operating in the Cincinnati, OH area since 1993.  She has been involved with creative arts ever since her artist mother handed her the crayons and pointed her towards the wall.  She has attended the prestigious Rhode Island School of Design as well as numerous workshops on faux finishing, muraling, trompe l'oeil and color theory, including all the major Faux Effects Silver and Gold product line classes.  She is also a certified Faux Effects instructor and teaches other faux finishers at many Faux Effects distributor studios.

Prior to Karen's involvement with faux finishing, she was a nationally award winning and published fiber artist.  Her love of textiles, as well as her graphic and fine arts studies at Rhode Island School of Design, are influences in Karen's faux finish and mural designs.  Additionally, Karen's understanding of color theory and knowledge of product characteristics and interactivity, contributes extensively to her ability to create unique faux finishes and to improvise with confidence.

Karen actively works in the field, allowing her to bring design salability, product usage and real life execution information to our clients. Her talent has been acknowledged in the form of numerous awards for Cincinnati's and Dayton's Homearamas, Northern Kentucky's Homefest and Cincinnati and Dayton Designer Show houses. She is a member of the International Decorative Artisans League and the Ohio Valley/Northern Kentucky Decorative Artisans Guild and is an American Society of Interior Designers Industry Partner.
