About Us

Ray and Peggy O’Sullivan opened their first pub in Mesa, Arizona in 1993.  In 2004 they opened their current location in Mesa on Superstition Springs Boulevard. They continue their proud Irish family tradition of providing the warmest hospitality to all who visit their Arizona sports bar, a tradition that has its roots in Ray’s native Glenbeigh, Ireland, a small fishing and holiday village on the northern lap of the famous Ring of Kerry, near Killarney in County Kerry.

MDA Shamrock Fundraiser

Annually for over a decade R.T.O’Sullivans has participated in the MDA Shamrock fundraiser that helps send kids with Muscular Dystrophy to summer camp for two weeks. All proceeds go to all aspect of running the camp, to help the great volunteers MDA has with this cause. Last year alone we raised over $4000 helping send three deserving kids to summer camp. Please click on the link below to see a video made by one of the counselors at this years camp at Whispering Hope Ranch in Payson, AZ.

Charity Golf Tournament

This past year we held our 23rd annual Trevor Griffiths Memorial Golf Event, raising over $20,000 for Hospice of the Valley. In the past 23 years R.T.O’Sullivans has raised over $400,000 for Valley charities, most notably ALS and Hospice of the Valley. We would not be able to do this without our volunteers, donations from our vendors and golf participants. We would like to thank everyone involved and look forward to many more years raising money for the Valley’s charities.
