Thank you to our clients, our factories, and our friends, for your support as we continue in our mission to provide you with personalized engineering services and first rate customer care.  We have celebrated our 40th year of serving the Southern California's HVAC community, and we know that our successful collaboration with you in your construction projects is the only way DMG will continue to thrive.

DMG Corporation was founded in 1967 by Al Dokter, Don Miller, and Bill Gebbie to represent the finest HVAC products in the Los Angeles area.  During the ensuing years, DMG Corporation has steadily grown from that partnership of three, into a thriving sales team with over 40 members working for our clients in our Whittier office.  From the days of our first President, Bill Gebbie, continuing through the tenures of Bob LeClercq and George Orff, and now under our current president, Ron Sweet, the focus of DMG has remained consistent -- we offer our clients personalized engineering service, to provide HVAC equipment and services which best fit your projects.  Our engineering staff is available to work with you, the building owner, consulting mechanical engineer, or mechanical contractor in the design, selection, and delivery of mechanical equipment. Our highly trained technical assistants and support staff are standing by to answer your questions. 

Over the years we have broadened our partnerships with manufacturers so that we can provide solutions on a wider range of projects.  To support this increase in our product lines, we have increased our inside and outside sales team to insure prompt service.   We now employ 12 outside sales engineers, and 6 inside technical support staff available to answer product-related questions and assist you with project design and quotations.  And, in January of 2002, we completed our third office remodeling project, to accommodate the added personnel.  Drop by and we'll give you the nickel tour!

We listen to you.  In recent years you told us that you needed faster support when looking for replacement parts.  In response we created DMG Parts in 2005, now providing easy access to parts for all the equipment we sell.  Click here to visit the DMG Parts page where you will find the link to contact Lenny and John for information regarding parts.

You also asked for immediate access to VFD’s and Water Source Heat Pumps.  Our warehouse is stocked with a full complement of these products ready to be picked up immediately.  Your DMG salesman is ready to assist you with stock VFD’s, and DMG Parts will help you find the right WSHP for your application. 

In 2006 DMG Corporation continued to expand by opening offices in Hawaii, Phoenix and Tucson. Please check out their capabilities by clicking on their links. 

Once again we offer our thanks for your continuous support over the last forty years.  We look forward to serving your needs for many years to come.
