Dear Friends and Clients,

It is with sadness that I share news with you of the passing of our president and founder, Donald L. Markley, PE.
Don passed away on Thursday October 22, 2009 in Peoria, IL surrounded by his family after a long and courageous
battle with Multiple Myeloma.  Don's remarkable knowledge, wisdom, and personality will be missed by all who knew him.
Although Don is no longer with us physically, his vision lives on in the legacy that is D.L. Markley & Associates.  For more
than 40 years, we have served our clients with personalized attention and quality work.  This will continue.  All of us here
at D.L. Markley & Associates remain committed to each and every one of you, and we look forward to our continued
relationships for many years to come.

All the Best,
Jeremy D. Ruck, PE
Senior Engineer
