The Harbour Gallery represents some of the best British artists working in the country today, including many Royal Institute and regional Institute members. Mark has worked closely with many partners over the years including hotels like Tresanton, Scarlet, Driftwood and Bedruthan and regularly holds exciting exhibitions both in-house and externally.

He has also launched two innovative website for the sale of art, a curated online gallery, BritishContemporary.art and in 2024, Mark was invited to become a member of the Arts Board at the RSA.
