Emmet Croke, Vice President of Operations

“I joined Nawkaw in 1990. Meeting our CEO, Russell Gray, through a mutual friend of mine, got me started at Nawkaw. I was hired to help the company expand into the United States. In 1991, we opened our office in Chicago. Starting out as a Stain Applicator, I have worked myself up the past thirty years. So much has transpired since then, and I am looking forward to what’s ahead.

During my leisure, I enjoy spending time with my family and close friends. I like playing hockey and golf, among other outdoor activities.”

Dave Ellis, Sales Manager Nawkaw

Dave Ellis, National Sales Manager

Hi, I’m Dave Ellis! It’s been an honor and thrill to be a part of Nawkaw in many different positions–now as the National Sales Manager. I took an unorthodox path to concrete and masonry stain, but after some time in public police service, promotions, and even a career in extreme sports, I’ve found my stride in architectural finishes.

I’m a people person, and I always bring the energy and a love of the outdoors to each meeting and industry event. I hope to see you there!”

James Maccario, Northeast Sales Representative

“As a recent addition to the Nawkaw Team, I look forward to custom making a color solution that fits your project’s needs. My background in the construction industry has provided me with extensive experience in consulting, sales, and project management. I believe color is transformative and produces many positive outcomes, such as happiness, energy, and power. I am eager to work with the team to bring creative and unique solutions to your commercial, residential, hospitality, and industrial buildings. 

Born and raised within the 5 boroughs of NYC, I consider myself a “true New Yorker.” I enjoy spending time with my new family, working on my personal development, riding motorcycles & relaxing in the Caribbean.”

“I’ve been a sales professional for 31 years, specializing in the wire and cable industry, as well as taking on roles in architectural sales for flooring and modular interior construction. I’m happily married and have a wonderful daughter. In my free time, I love staying active as a runner and cyclist. I’m an outgoing person and always eager to contribute wherever I can.

Jeff Preisner, MidAmerica Sales Representative

“I’ll be representing Nawkaw in the MidAmerica Region which is comprised of Kansas, Missouri, Oklahoma, Arkansas, Tennessee & Mississippi. I’ve enjoyed an extended career in the concrete and masonry industry. Spending virtually all of it in this region. I’m looking forward to rekindling those relationships.

When I’m not working, I’m spending time with my family, friends and serving my community. If there is time left over, I enjoy playing an occasional round of golf.”  

Jeremy Penney, Northern Midwest Sales Representative

“I’m very excited to be part of Nawkaw as a Sales Representative for Nawkaw in Chicago! I spent the past twelve years in the commercial roofing trade before becoming a part of the NawTeam.

I’m a native of Chicago and a father of three daughters. Outside of work, I’m an avid learner and enjoy reading about business and personal development. I’ve also competed in martial arts (Brazilian Jiu-Jitsu) for twenty-three years, making me innately competitive! I enjoy running, hiking, swimming, and vacationing anywhere near a clear blue ocean with white sand.
