Our team calls itself “The Wonder Engineers” because our goal is to leave every event attendee with a sense of magic and fulfillment that is authentically Kansas City. The type of magic that lives within and beyond those who attend our events is not accomplished spontaneously; this sense of wonder has been thoughtfully and intentionally developed. Our true understanding of what inspires and ignites the soul of our beloved community is within every detail of the public and private events produced by the O’Neill team, and THIS is what truly sets us apart from others. The Wonder Engineers is a team made up of women, working in harmony with each other and our clients to orchestrate events.

O’Neill Events & Marketing was founded over 70 years ago by Pat O’Neill Sr. as an ad agency specializing in public relations and event publicity. Twenty Years later his son, Pat O’Neill Jr grew the business as a consultant, publicist and media spokesperson for entertainment venues and important civic issues in Kansas City and throughout the region. Retiring in 2018, Pat passed the reins to his daughter Keli O’Neill Wenzel. O’Neill is now female owned and operated located in the heart of downtown Kansas City, MO. We take pride in our logistical talents and our extensive experience in creating, planning, managing and orchestrating many of Kansas City’s most iconic events.
