DOZENS OF HOUSTON do-gooders chilling in Colorado this summer gathered for a mountain-chic soiree in support of Memorial Hermann.

A two-day celebration in Aspen, chaired by Melissa Juneau, Leticia Trauber and Hallie Vanderhider, culminated in the announcement of a substantial $5 million gift to the hospital system’s Life Flight — the nation’s first and busiest air-ambulance program.

The donation, made by the John M. O’Quinn Foundation, marks the launch of a campaign to purchase new helicopters for Life Flight, which supports the highest-volume Level I trauma center in America. Previous donations by party attendees Charlie Lusk, Jim Smith and Laurie Krohn, along with the John S. Dunn Foundation, helped Life Flight acquire its current fleet. Partygoers raised their glasses, filled with potent “Red Duke” cocktails homaging Life Flight’s creator, to everyone who has contributed to the groundbreaking — and high-flying — program.
