“Insanity is repeating the same thing and expecting different results.”
Two Approaches to Client Success
A member of the Concannon, Miller & Co. team since 1980, John Sharkey breaks his business philosophy into two approaches: “Always exceed client expectations” and “Provide excellent service all the time.”
Plenty of Guinness in Ireland
When not at the office, John enjoys sports, movies, and reading, with John Grisham being his favorite author. In fact, if stranded on a desert island, John says the three things he would need are a Grisham book, a computer, and plenty of Guinness (he also brews his own beer). His favorite vacation spot is Ireland.
Steady as She Goes
John says his friends and family would describe him as “nice but quiet,” while he would describe himself as “steady.” His wife Jill and his daughters are his most prized possessions.
Organizations that John donates his time to include the South Parkland Youth Association, the Association for the Blind, and the Lions Club.
