Opened in 1986, Olivia Keenan’s is the longest-running beauty establishment in Co. Monaghan, coming up on forty years in the same trade. It operates as both a salon and a school of beauty, which matters to clients as well as students — salons that teach have to keep their techniques demonstrably current. Facials, nails, waxing, brow and lash work and massage are all covered. Four decades in a county this size means the client base spans generations.
