Who We Are
Pony Express Maintenance Corporation (PEMC) was established in 1978 by a young Nam Chang and his wife with a mop and a dream. Our small family owned minority business has been providing excellent, efficient and high quality janitorial services, building long-standing and reputable relationships with over 250 businesses and locations we've maintained in the Portland Metro and Vancouver area for over 37 years.
Among PEMC's extensive clientele list, we've had the great honor and pleasure of servicing two of North America's manufacturing giants in Portland, OR. Since first contracted in 1981, it were these companies that first realized PEMC as a hidden jewel and afforded us the great opportunity and privilege to grow alongside and be a part of their company's history and fabric - seeing and inspiring a potential far bigger than what Nam Chang, Founder, had ever imagined possible when he and his wife Diana, Co-Founder, picked up their first mops and began knocking on doors.
PEMC has, over the years, faithfully and consistently demonstrated exceptional professionalism and performance to identify, meet the needs, improve and compose dynamic and beneficial solutions to the overall cost, cleanliness and best interest of our clients.
