John began studying electronics in the U.S. Navy in 1950 and served during The Korean War. John worked for TRW, DRESSER, and sold chemicals for the electronics industry in the late 1970’s.
In 1983, John Lankford, Sr. purchased Electronic Services Unlimited, Inc. and began the ESU
tradition of excellent workmanship, attention to detail, and great customer service. His Navy training
and work experience was pivotal in the success of ESU. John took time building relationships with everyone around him.

His work-ethic and sense of humor made him stand out as a leader who understood what it takes to
not only get the job done, but get it done with a smile. John passed away in September 2012 at
the age of 80. Upon hearing the news of John’s passing, one of our customers said, “it’s the end
of an era.” His “infectious” laugh and gray beard will be missed by all of those who knew him.
