    Digital Strategist and CoFounder

    Digital Strategy as well as direction and mentoring of our team and our business.

Leanne and her team have been working with us for about 18 months. They got our 3 websites up to date, got regular newsletters, blogs and social media posts going out, got our marketing campaigns structured effectively and so much more. We are really impressed with how she made things happen and got us sorted out and organised. The marketing campaigns are working really well - we used to be a 50 year old company that no-one had heard of and now people we meet say "Ah yes, we've heard of you". And we get a full house for our Boardroom Briefing presentations. If you need someone to get your marketing sorted, I strongly recommend that you give Leanne a call!

I would just like to say how fabulous Leanne has been to work with. Her courses have so much information in them - the process is easy - the steps she sets out are achievable, and she is always contactable when you need to ask her those little questions that you just can't seem to fix.

I think she is also one of the few people who I manage to last an entire webinar listening to. I love what she does - and with the minefield that can be the process of social media - Leanne makes wading through it all so much easier. Can't recommend her highly enough!

Loved Leanne’s Instagram Training.

Being a newbie I had absolutely no idea what I was doing. Leanne explained how to find my target market on the platform and how to do my hashtag research to get maximum exposure. She also gave me content and branding tips for what was popular on Instagram.

Plus, it is working!
