Oli first started working with Simon in 2012, when he took up the role of chef de partie at the then pop-up restaurant Roganic, the Simon Rogan establishment he would later lead to its honorary one MICHELIN-star status upon its permanent return in 2017.

In the intervening years before returning to Roganic, Oli honed his skills through a string of impressive tenures across the world. His early experiences included positions at a trio of three Michelin-starred restaurants; Eleven Madison Park in New York City, Maaemo in Oslo and The Fat Duck in Bray, before finally landing back at Roganic in London as head chef. Oli’s deep understanding of Simon’s signature style of cooking and his focus on exceptional ingredients earned Roganic its first coveted Michelin star.

In early 2019, Marlow assumed the role of executive chef at Simon Rogan’s first overseas restaurant venture in Asia, Roganic Hong Kong, which opened alongside Rogan’s development kitchen Aulis in the heart of Causeway Bay. Roganic Hong Kong was awarded a MICHELIN star less than ten months after opening and also received a MICHELIN Green Star. Oli also leads Simon’s Hong Kong bakery and natural wine bar, The Baker & The Bottleman, which opened in January 2022, as well as the two MICHELIN-starred ION Harbour in Malta, which Simon took over in March 2023.
