Our Personnel

Hank Zemola – Founder & Chief Executive Officer
If there were ever a pioneer in the field of event management, it would surely be Hank. A lifelong Chicagoan, he founded Special Events Management (SEM) in 1988. Since that time the company has grown to become the largest full-service producer of runs/walks, art/street fests and other special events in the Midwest.

Leading by experience has been his model. A former event director himself, and former executive director of the Chicago Area Runners Association (CARA), Hank has directed more than 800 running events including the Shamrock Shuffle and YME Race Against Breast Cancer where he was honored as race director of the year.

Within the festival and other special events community, Hank has been the director of some of the largest festivals in the City of Chicago including Northalsted Market Days and the Wells Street Art Festival in addition to other top special events that include:

  • National Championship of Cycling
  • National Championship of Inline Skating
  • National Championship of Inline Hockey
  • World Championship of Inline Hockey

Hank started in the event business at an early age after working at United Parcel Service in a management role where he claims the foundation of hard work and high quantity taught him the basis of a good business operation.

After UPS he owned nightclubs and managed music venues which included TUTS, Stages (now the Metro) and the Vic Theatre. A musician in his youth, he became a skilled talent buyer of national entertainment. He later served three years as executive director of the then-infant Chicago Area Runners Association before founding SEM.

Today Hank’s company produces more than 70 annual runs/walks and art/street fests, concerts and provides assorted services to scores more. He also oversees the company’s eight event managers.

An active member of several Chicago area civic and professional organizations, one of Hank’s primary visions since founding the company has been to produce events that raise money to benefit non-profits, community/neighborhood groups, chambers of commerce and scores of others.

Veronica holds two key positions at SEM. One is as director of Event Bright! A department that staffs for all warehouse, street team and cleaning services.

Before joining SEM, he was a business analyst with human resources/consulting giant Hewitt Associates. Off-hours Steve enjoys music and outdoor activities.

Bruce Buzil – New Business Development
As SEM’s new business development consultant, Bruce likes a challenge. A lifelong Chicagoland resident, he’s always on the hunt for identifying opportunities for the company. This runs the gamut from finding new events and ways to expand existing events to selling event sponsorships. At day’s end, Bruce will be the first to say it’s all about building relationships. Before SEM he was a partner in a broadcasting company that owned radio stations in small and medium markets nationwide. He was also a partner in a company that owned and managed marathons around the country. In his free time the father of two sons likes to relax by biking recreationally.

Gehrig Peterson – Music Director
One of SEM’s most veteran staffers, Gehrig has been affiliated with the company since 1990. He has an extensive background with Chicago radio stations in sales and promotions, and a phenomenal talent-buying resume that spans more than three decades. His relationships with local, national and international music acts and managers verges on legendary.

Each year Gehrig books nearly 250 unique music performers for scores of SEM-produced events. This includes bands, solo artists and deejays. While many are from the Chicago and the Midwest, large percentages are big name headliners he secures for SEM’s street fests from the U.S. as well as internationally.

Gehrig’s unique background allows him careful insight to contract negotiations and talent requirements associated with execution cost. All this benefits client budgets and the success of festivals.

In addition to his music background, Gehrig serves as a key account manager for some of SEM’s most important corporate sponsors. With 30 years in radio, Gehrig has also has long-lasting relationships with the advertising and marketing communities.

Karyn also oversees SEM’s Web-based marketing efforts including maintaining/updating the company’s website with its 500,000 unique monthly visitors, and compiling and disseminating SEM’s weekly E-blast newsletters to nearly 100,000 subscribers. In a bit of trivia, the consumer “click through” rate on SEM’s website is an amazing 6 percent vs. the national norm of only .2 percent.

In addition, Karyn oversees the company’s social media marketing (including Facebook and Twitter) and manages creative planning and logistics with SEM’s graphic design department. A graduate of Illinois State University, she joined SEM in 2002 as an event manager.

With SEM for more than 13 years, it’s no exaggeration that he’s designed hundreds of logos as well as collateral pieces that include posters, postcards. brochures, advertisements and much more.

Today many of his creations are trademarked with copyrights used by both SEM and many of its clients. Sean also has vast expertise and knowledge of the latest design technologies and state-of-the-art hardware and software.

Born and raised in northwest suburban Park Ridge, Ill., Julia headed to the sunny Southwest to earn a degree in communications from Arizona State University in Tempe before returning to the Windy City for a marketing job with the Chicago Fire soccer franchise.

Off hours, she’s a huge fan of both country music and the Chicago Bears.

Anisa Peraica – Event Manager
To use the word “reinvention” to describe Anisa would be, to put it mildly, an understatement. From gigs as a TV writer/editor/producer in both Chicago and New Orleans to waitress stints and playing soccer to her work on a downtown Chicago urban art project, there’s very few things the Chicago native hasn’t done. For Anisa, it’s all about the challenge.

Matthew Perez – Event Manager
A love of running that began in grade school helps explain Matthew’s niche at SEM where he specializes in working on more than a dozen runs including full and half marathons.

Gabby Webster – Event Manager

It’s there where she gained an appreciation for all aspects of planning events. She holds a bachelor’s degree in business administration from Chicago’s Robert Morris College. Now living back in the city, Gabby enjoys exploring the eclectic culinary offerings of neighborhood restaurants during her off hours.

An attention to detail serves him well in planning events and on-site event logistics. Off hours, James enjoys recreational running and dining at Chicago’s ethnic restaurants (Polish food is a favorite). He’s also a fan of ‘80s hard rock music and tinkers with exotic cars like the DeLorean (his uncle owns the world’s largest collection of custom DeLoreans).

Daniel Oleksiuk – Production Manager
Although his official title is production manager, Dan is better known around SEM as warehouse manager, trade show manager and carpenter extraordinaire. A true chameleon, he pretty much does it all! The Northbrook, Ill., native (where he still resides) earned his bachelor’s degree from Chicago’s Columbia College in music, business and concert production. But for those who know him, his true passion is for building things. From showcase booths for the SEM-produced Chicago Flower & Garden Show, to intricate exhibits at national trade shows for Fortune 500 clients of SEM’s trade show & exhibits division, his detailed craftsmanship is awe-inspiring. During off hours Dan, whose parents immigrated to the U.S. from Ukraine, enjoys sports and music.

Rosalia Robinson – Exhibitor Relations Coordinator
Rosy works hand-in-hand with Joe Persfull, the company’s exhibitor relations manager, in coordinating SEM’s relationships with vendors.

A resident of the near southwest suburbs, Rosy started at the company in 2010 in administrative positions that led into her current role.

Fred Newton – Communications Manager

Fred’s a focused writer, voracious reader, hard-nosed editor and quick study on virtually any subject. From writing more than 200 SEM event releases each year to disseminating information and working with scores of media outlets (print, electronic and Web-based), he’s adroit on numerous fronts
