Leanne O'Sullivan

I help businesses grow through strategic digital marketing.​

I am the founder, CEO and Digital Sherpa of Adventure Digital – a marketing agency based in regional NSW, servicing clients all over the Australian eastern seaboard.

I’ve made it my life’s mission to help you grow a sustainable, enjoyable and profitable business. 

I have worked with many industries over the last 20 years of all sizes, in all sectors with people of all ages and abilities. I have delivered countless webinars, spoke at numerous events, delivered many workshops, trained, mentored, educated and entertained hundreds of small business owners just like you.

I love this industry and I love working with all businesses – together we can conquer digital marketing.
