management level in the voluntary, education, creative and housing sectors. Specialist knowledge and passion for: learning/personal development (beneficiaries, staff, and trustees/stakeholders), creative communication (film production, campaigns, storytelling), and delivering efficiency and financial strength.
The work I most enjoy is the support I provide to those in leadership positions - CEOs, Chairs and leadership teams – to enable talent and potential to flourish within others. It has been an exciting journey watching Tayshan and Grow2Know build not just a brand but a movement. They have built phenomenal success in a short space of time with endless possibilities ahead; a light shining so bright at a time when we most need new hope.
