    Liz Holt, Executive Director

    Liz's passion for dirt and Indiana Jones led her towards a Degree in Archaeology from the University of Calgary in Alberta, Canada. Archaeology has since taken her throughout Canada, Europe and Asia in search of both ancient cultures and great food. After spending a few too many years in the ground, Liz turned her gaze skyward and returned to the University of Calgary to acquire a Masters Degree in Architecture with a specialization in the science of materials and building enclosures. The marriage of her two disciplines lead her to Australia for 9 years, where she worked to conserve both historic buildings and archaeological sites during development. While down under her blood happily thinned to manage days at the beach and the eternal summer of Sydney.
    In 2011 Liz followed her husband's University career to the US and landed in Oak Park. After spending three years working for a local tile supplier, Liz has now firmly landed with her feet on the ground at the Chamber of Commerce where she peruses her passion for helping small businesses thrive and finding the best coffee in town.
    Liz lives in Oak Park in a classic Chicago bungalow where she still pursues her passion for dirt and soil by farming every inch of her back yard. She lives there with her hubby, a real-life Indiana Jones, two feisty daughters and a cat who was not left behind. The only thing left is for her blood to thicken-up to deal with the winters in this great city!


    Mark Walden, Program Manager

    Mark is Program Manager at the Oak Park Chamber of Commerce, and at other times of the week wears the hat of a property manager, nonprofit fundraiser, or snow removal contractor.  He sometime looks goofy due to wearing all those hats.  Mark appreciates the OPRF area for its independent businesses, trees, garage sales, and architecture.  But he lives in Chicago because that's where his wife and his ultimate frisbee game are.

    Janice Moskoff, Special Events Manager

    As the Manager of Special Events at the Oak Park – River Forest Chamber of Commerce, Janice couldn’t be prouder to be working with talented Chamber staff and members to support small business throughout our community.

    Janice also runs the 1,500k+ strong OPRF MOMentum Facebook group connecting area moms to local work, volunteer and life opportunities. In her past work life, Janice ran her Chicago-based sample sale retail & event business, Beta Boutique. At its peak, Beta Boutique was regularly featured in local and national media such as MSNBC, and even selected as the Chicago representative for a national ad campaign featuring Stacy London from What Not To Wear. By 2010, the business had 10k+ subscribers and won best-in-class accolades from top Chicago publications, Time Out Chicago and Chicago Reader.

    While she is not working for the Chamber, Janice is dreaming up new entrepreneurial ventures and doling out solicited and unsolicited advice to her business friends. She also spends her time hugging her oversize dog, Duffy, reading books, learning tennis, doing yoga, organizing all things for her family of four, and planning multi-generational trips for her extended family of 20. If you have good ideas on books to read or places to travel, contact her anytime.

    Ronnie Marlin, Communications Manager

    Ronnie's meteoric rise through many industries finally landed him at the world renowned OPRF Chamber.

    As a child actor he was featured in many cereal commercials, photo shoots for high end department stores like Mervyns and one feature film with Wynona Ryder. After graduating from Arizona State University with a Broadcast Journalism degree he ventured to Hollywood to put that degree to no use at all and got into film production. With stints at NBC, Disney and Universal Pictures he knew that his true calling was in a town where he knew no one, had no job contacts and had never owned a winter coat (outside of a ski parka), so it was off to Chicago, natch.

    It was a perfect fit. River North, Wrigleyville and the South Loop, there was nowhere he would not live and no industry that he wouldn't try his marketing skills at. Property management, consulting, tech trading and at one point, doggy daycare. Until it was finally time to grow up, get a part time job and raise a family in one of the area's most expensive suburbs. Luckily he's surrounded by a plethora of Star Wars fans, a great wife and child and a helluva great team at the Chamber; who all have endless patience with his ADHD and constant interrupting.

    Kosha Carstens, Sponsorship Coordinator

    A lifetime student, Kosha received her BS in Biology from Illinois Wesleyan University, her MS in Neuroscience from Michigan State University and her MA in Bioethics & Health Policy from Loyola University. With a recent move to River Forest with her family, Kosha is excited to give back to the OPRF community that has so openly and warmly welcomed her and her family. 

    Kosha is a self-proclaimed and proud nerd. She is a bat enthusiast (yes, Chiroptera, the flying mammal), and spends much “free” time on education and conservation of those faces that only a mother could love. She and her family are also avid Batman fans, calling themselves the Carstens BatFam, with no trace of irony. She lives in her BatCave with her husband, Brian, an amp technician (and local small business owner himself!), their daughter Anushka (aka Batsy), and their two cats, Frances Harley and Harvie2Face. Whether it is Batman, bats, Harry Potter, the music of the great Freddie Mercury or the tragically lost Chris Cornell, experiencing the world through travel, mental health advocacy, evolution, laughing loudly or My Little Pony marathons with Batsy, Kosha is all in. She is excited to work for the Chamber of Commerce (Chamber of Secrets??) to bring the local business community to its highest potential. As Wil Wheaton says, “Being a nerd is not about what you love, it's about how you love it.” Nerds Unite!
