Building The Future Together

Kevin O’Toole is not only one of the Principals of Hunzinger and a seasoned construction professional, he is also an accomplished musician and his band, H2-OH, is celebrating their 13th annual appearance at “The World’s Largest Music Festival.” They will be playing at Summerfest’s Briggs & Stratton Big Backyard with Coors Light and Tap Milwaukee Stage on Saturday, July 8th from 4:00 – 5:30 PM. Headlining that evening is Dennis DeYoung: The Music of Styx at 10:00 PM.

The Summerfest grounds are located at 200 North Harbor Drive on Milwaukee’s lakefront and the Brigg Stage is part of the South End Development completed in 2011 that we are proud to have served as Construction Manager. Hunzinger self-performed many divisions of trade work including all concrete work and some carpentry and masonry work.

H2-OH is Henry Lewis, II and Kevin O’Toole.  Each have been performing individually for more than 30 years and they came together to create H2-OH, a contemporary folk/rock duo that combines original music with select cover tunes that share their real life experiences in a soulful and passionate way.  Their focus on high quality show production has resulted in their becoming a Milwaukee favorite as a live act.  They are a regular at Summerfest and Zoo Ala Carte and have had the honor to share the stage in support of national headliners Lindsey Buckingham, Don Felder, Los Lonely Boys, John Hiatt, The Gin Blossoms, Dan Navarro, The Jerry Garcia Band, Sam Llanas, Janis Ian, Tom Chapin, The Bodeans, The Family Stone, Foghat, and Bucky Covington, to name a few.

We invite you all to experience their show.  For more information on the band or to see other upcoming dates, check out their website at
