You may reach us by phone, email, or mail per the instructions below.  As a small firm, we do not maintain onsite office-hours staff.  You therefore may get voicemail when both John Campbell and Martha DeLong are not available.  (We are also reachable by cell phone to all clients, as well as prospective clients with whom we have corresponded.)

PHONE:

503-221-2005

As we are based in Oregon, we generally keep US Pacific Time office hours.

EMAIL:

To contact Martha DeLong, use MarthaD followed by the usual "at" sign and the domain cdri.com.  To contact John Campbell, use John prior to the "at" sign.  Of course, if you are in a hurry, or if you do not hear back from us in a timely manner, please call us at 503-221-2005. We look forward to hearing from you!

In the fall of 2019, we moved our offices from our long-time Portland location on NE 33rd Avenue.  Our new mailing address is:
