Why work if you can live your passion. Dennis has been working in the Advertising industry for at least two decades with many large network agencies, including TBWA, Publicis and Ogilvy. His career covers client service and management on multiple levels, from production and traffic to art-buying and project management. Founding the company in 2013 enabled him to work with a great team of people and passionate clients. A Mario Cipollini lookalike on the bicycle with flashy outfits and a Land Rover Defender fanatic with a devil-may-care attitude towards his children riding motorbikes, to the great dislike of his spouse... on all topics.

Gavin co-founded Sol & Matheson in 2013 to build on his public relations experience and take client service to the next level. His career has included several years in motorsport as press officer for Yamaha in the World Superbike and MotoGP Championships as well as account management roles on FMCG, entertainment and consumer clients in leading London agencies that include Jackie Cooper, Henry’s House and Shilland & Co. A self-confessed petrol head, he has a compulsive habit of buying unreliable but characterful cars and motorcycles as well as sharing his gin addiction with the world.

Behind every successful company there is a strong, wise and hardworking woman, as if Graucho Marx had personally met Mariëlle. She is the conscience of the company, keeping an overview of daily office operations, taking care of the crew and making sure we draw between the financial lines. Don’t be fooled by her size as her impressive Thai boxing skills make her a woman not to be messed with. Out of the office she easily transforms into a mother of three, always in high heels and always glamorous. No kiddy drool is going to mess that up.

Marielle Sol


Kenny arrived at Sol & Matheson in 2015 as a Project & Account Manager. He runs a variety of projects on a daily basis and loves looking for things to surprise the client with as well as looking for new (business) opportunities. Since the start of this millennium he developed a broad experience in various Marketing and Communication areas with a wide range of premium brands as clients. An unsinkable happy camper, raised in, on and with motorcycles, who likes to know a bit of everything and is a massive USA addict.

Kenny Boon


Toine has been a tour coordinator, truck driver and mechanic with Sol & Matheson since 2017 and spends his time running experiential tours throughout Europe. A technical wizard with all things two wheeled and motorised he’s always at home getting eager riders out on the track with the right machinery. When he’s free from work, he enjoys indulging his love for all things Italian; from wine and cheese to fine cuisine. Bellissimo!

Toine Boessen


Alex joined Sol & Matheson in 2015. He began as an event manager coordinating customer events across Europe. He quickly developed into a project manager and now coordinates all logistics, staff and planning for our multiple pan-European experiential tours. With a history in automotive, transport and coordination projects he is a master in finding solutions for logistics throughout Europe. With an irrepressible sense of humour, when not conquering the roads of Europe Alex can be found either out on his motorbike with friends, or fixing it (it’s a Ducati).

Alex Ploeger


Michael is part of the SMC family since 2016. A self-taught graphic designer that also holds a masters degree in Corporate Communications. He gained is experience as a designer in the streets of Amsterdam and therefore likes to see himself as a bit of a pirate. In the past few years he worked as designer and communications specialist for well-known international brands in industrial, financial and business service sectors as well as for non-profits and governmental organizations. He tends to consume quite some coffee and he likes to match his sneakers with his t-shirts.

Michael Groen


Sam joined us in 2019 as a Content Manager and Copywriter. With over three years of experience in Public Relations, Event Coordination & Hospitality Management, Sam supports a range of exciting clients and projects. He is a passionate communicator and loves getting stuck into new copy work, creative projects and pretty much anything he can apply his creativity to. When he’s not writing Sam can be found with a pencil in hand drawing portraits or engrossed in a good book.

Sam Walker


Maarten is a wanderer at heart and as one of Sol & Matheson’s event managing, truck driving mechanics, he gets to wander as a part of his daily routine. Running experiential tours throughout Europe, Maarten puts years of knowledge built through diverse roles fixing everything from motor bikes to jet-skis and handling businesses from bars to adventure tours to great effect. He lives life on two wheels and when he’s not working he’ll be finding winding roads somewhere in the mountains of Europe or tinkering with engines in the garage.

Coming off the back of almost a decade spent working at the Heineken experience in Amsterdam, Jos knows what it’s like to run largescale public events under extreme pressure. His role in the company is Hospitality Coordinator and he spends his days setting up, coordinating and martialing the hospitality services at racing events around Europe. When he’s not hard at work he’s working out hard or showing off his skills on the football field. True to his roots, he can be found after the work is done with a Heineken in hand.
