Marcy Kostewa, CPMR

Marcy Kostewa (owner) started in the business in 1978 as
a resident salesperson for Gamson Electrical Sales,
headquartered in Southern California.  She gained
experience by selling lines like Allied Tube & Conduit,
Quality Wire, Coleman Cable and Circle F wiring devices,
to name a few.

In 1981 she had the opportunity to start her own agency
with many of the lines listed above, in which she was an
active partner through 1987.  At that time, she focused all
her efforts on a pipe fabrication business that she had
started as a complement to the Allied conduit sales.

In 1989 manufacturers asked her to start up an agency.  
Now in it's seventeenth year, she holds an impressive
background in the business, not only in sales but
industry posts.

Marcy is a Past-President of the Electric League of
Arizona, Central Chapter, and served as Chairperson of
the 1995 Electrical Expo.  She is also active with the local
International Association of Electrical Inspectors (IAEI),
National Association of Women in Construction (NAWIC),
Building Owners and Managers Association (BOMA), and
Arizona Power Quality Association (APQA).  Marcy is a
graduate of the Certified Professional Manufacturers
Representatives (CPMR), a certification program offered
by the Institute of Professional Advancement.
