OUR TEAM: Collaboration in action.

With over 150 combined years of experience, Cascade Music Collective is a team of Entertainment and Hospitality industry professionals, each with exceptional experience in their respective fields.

  • Seattle Event Solutions

    Keri started her career in Production Management, Stage Management, and Lighting Design and continued to work in live entertainment for over 12 years.

    In 2009 she took a leap of faith and became the Co-owner / Beverage Director of the Stumbling Goat Bistro, one of Seattle’s most beloved farm-to-table restaurants. Keri fell in love with the food and beverage industry and found herself torn between her two passions, but rather than giving up one for the other and realized there had to be a way to both.

    In 2012, she helped start Seattle Event Solutions, a company which could portray the finest example of bar services for an event or festival of any size. Since its inception, Keri and Seattle Event Solutions have provided support to Cirque du Soleil, Teatro Zinzanni, the Marymoor Park Concert Series, Pier 62, Bumbershoot, Day In Day Out Festival, Double Major, and Capitol Hill Block Party. Keri has become one of the most sought-after subject matter experts in providing Food and Beverage Service to live events and festivals within the City of Seattle.

    When it comes to concessions, Keri is an inspired legal and logistical Food & Beverage provider and master technician that delivers a once in a lifetime experience for the arts community she serves, the young professionals she mentors, and her respected clientele.

  • Cascade Music Foundation

    Angie started her catering career with the experts at companies like the Sheraton, Marriott and Lowes Hotels.

    In 2000, she moved to Seattle and her solid corporate catering experience landed her a position as the Operations Manager at Benaroya Hall, which eventually led to her appointment as the Senior Food and Beverage Manager at Bell Harbor International Conference Center, where she managed events for up to 5,000 attendees.

    Nearly a decade after moving to Seattle, Angie stepped away from the corporate world and joined forces with Keri DeWoody to open Stumbling Goat Bistro. Over the next eight years, Angie devoted herself to making the restaurant one of Seattle’s earliest locally-sourced, farm-to-table destinations. It was an environment that delivered daily challenges and required Angie to seamlessly transition across a multitude of roles – from bartending to accounting to cooking – yet her most cherished memories trace back to the service she provided to new and returning patrons.

    Angie has since brought her unique set of experiences and management skills to Seattle Event Solutions, where she heads up the Private Event Department and Contracts and manages the Clise Mansion at Marymoor Park. Since May 2018, Angie has regularly attended and contributed to Friends of Marymoor Park committee meetings.

  • Mammoth Live

    For the better part of three decades, Sean Striegel has been a recognized leader in the live entertainment space.

    Since Beginning his career in Southern California as an independent promoter, Sean Striegel has has been on the forefront of the ever-changing live music space. In 2000 jumping from Independent to a corporate structure, Sean Striegel joined the House of Blues organization (HOB) as the Talent Buyer for the Anaheim Venue. In his tenure at HOB, Sean and his team achieved Most Tickets.

    Sold for a Club Venue as posted by Pollstar Magazine, and in 2005 Sean Striegel was awarded the Nightclub Talent Buyer of the Year award, recognizing him as the best Talent Buyer in the club space for the entire world.

    Since then Sean has been nominated additional times. During Sean's time there, HOB Anaheim was the most profitable venue per square foot in the entire organization. Growing the music scene in Southern California, Sean Striegel began promoting shows outside of the club size scope and promoted shows in the Ballroom, Boutique, Large Theatres, as well as the Festival business. Eventually HOB was purchased by Live Nation, and Sean was elevated to the position of Director of Clubs and Theatres for Southern California.

    2007 saw Sean relocating to New York with the promotion to Vice President of Music. In New York Sean oversaw the booking teams for not only club venues, but for the theaters, ballrooms and 3rd party venues. In New York, Sean began to expand on his role in his business, and was promoted to the position of Senior Vice President, and the Regional lead for talent for the Club and Theatre division. Within that position Sean was responsible for not only the bookings of shows, but running the business for the region. This included being responsible for the P&L of the entire region, business development, team leadership and development, coordination of all aspects of the business from booking to box office, marketing to sponsorship and all other factors to the concert business. On any typical year, Sean oversaw and was responsible for over 1,000 events annually. One area Sean excelled at was the creation and management of new business partnerships. These new partnerships were with new venues, public and private corporations, municipalities as well as private individuals. Known as someone who did as he said, Sean is well respected in the area.

    Throughout his time in New York, Sean promoted shows at all levels from clubs and all size theaters, to both boutique and full-scale amphitheaters, large scale performance venues, theme parks, arenas, and in the festival space. There is nothing like booking a show at the “Worlds Most Famous Arena”, Madison Square Garden. "It’s just so iconic," Mr. Striegel has stated. In addition to individual show bookings, Sean began producing national tours for his company. These tours would not only prove to be extremely profitable, but created new business relationships that exist to this day. After more than 20 years with Live Nation, it was time for a change.

    In 2022 Sean partnered with Mammoth Live to expand their business and increase their national profile opening Mammoth Northeast. In that same year, Sean joined the Cascade Music Collective, joining coworkers from his past as well as new relationships with well respected leaders in the entertainment space from the Pacific Northwest as the lead on Talent. Building upon the live music space, Sean will continue to grow business, create opportunities, and as Mr. Striegel himself would say, “Do some shows with our friends."

  • Promovere

    Andy is a seasoned marketing executive and brings over two decades of experience to the Cascade Music Collective (CMC) team.

    With roots in artist management in the California and Seattle music scenes, in 2002 Andy joined CMC talent buyer, Sean Striegel, at House of Blues’ club division in Anaheim, California, before moving on to the 6,000-seat Gibson Amphitheater in Burbank.

    Andy returned to Seattle in 2006 to accept a new opportunity with AEG to launch its regional startup. There, he was tasked with expanding AEG’s regional footprint and brand recognition, and was responsible for all show and tour marketing in Washington, Oregon, Idaho, Montana, and British Columbia.

    During his tenure with AEG, Andy oversaw the integration of the Showbox Presents brand, launched the Marymoor Park Concert Series, and managed the rebrand of Seattle’s Bumbershoot Festival. His final project with AEG was the highest-grossing concert in Seattle history: The Rolling Stones show at the 72,000 capacity CenturyLink Field. Under Andy’s leadership at AEG, his team was responsible for marketing more than 4,000 events—in clubs, theaters, arenas, and stadiums.

    In need of a new challenge, Andy resigned from his position at AEG in early 2019 to open his own marketing agency, Promovere. Andy currently works with clients including Southern California’s Desert Daze (“Festival of the Year” nominee – Pollstar 2021), the Emerald Cup (Northern California’s largest cannabis festival & competition – recognized by Rolling Stone as the “Academy Awards of Cannabis”), and Mammoth Live, helping to expand their regional footprint in the Northeast.

  • Shane began his live music career at House of Blues in Orlando, FL. The company's core values of inclusion and equality would help shape both his management style and love of team building. He worked his way from an hourly security position to bar manager before moving to open House of Blues Las Vegas where he learned about nightclub promotions and expanded his restaurant operations experience. Later Shane was promoted to Director of Music Hall and Foundation Room operations at the House of Blues Los Angeles where he learned fine dining operations and continued his live music venue management development.

    Shane furthered his House of Blues career in San Diego managing the operations of both House of Blues San Diego and the 4th and B Theater where he also handled outside promoters and booked club events. After moving to Seattle, Shane reconnected with Andy Roe, an old House of Blues comrade who recommended he apply for an operations job with AEG Live. After interviewing and accepting the position as front of house manager for the Showbox venues, Marymoor Park Concerts, and Bumbershoot Festival he taught himself large event line management, operational logistics, contracts, bids, and site operation build outs over three years and worked his way up to Assistant General Manager of the Pacific Northwest. Shane attended the Friends of Marymoor Park meetings for three years as the face of AEG to communicate with both Parks and the local community.

    After resigning his position in 2018, Shane was offered and accepted the opportunity to join Keri and Angie with SES as an event manager for Marymoor Park Concerts and Bumbershoot Festival. He's looking forward to building upon his experiences as a founding member of the Cascade Music Collective.
