John andMatthews
Senior Consultant

I bring passion and experience to serve clients in some of the world's most progressive organisations - enabling leaders to perform at their best. I'm told I have an engaging and inquisitive style that connects easily and am particularly effective at getting people to see the wider context. I enjoy adventure and love nothing more than exploring the wilderness with family and friends or tackling an unusual sporting challenge.

Hillary andO'Dell
Project Manager

I am a program manager, and I love that every day is different, from working on different tasks involved to make a program run smoothly to talking and meeting clients. I come from a hospitality background, so I love the client-facing aspect of my role here at Impact, as well as making sure every piece of the program is on schedule. Outside of work, I am always doing something like teaching dance, travelling, and going to the beach!

Assistant to The Boss

I support the CEO in an exciting and super varied role - from Board meetings to barbecues and everything else in between. An Impacter since 1999, marketer and mum, I have a need to be outdoors every day - no matter what the weather! For me, Impact is a unique place where people matter and my work and life can intertwine through flexible working and trust.

Senior Consultant

I have spent my career exploring, researching, teaching, coaching and practising leadership skills. I love working with individuals and groups to tackle hurdles and develop strategic initiatives. When I am not designing programs, I like to spend time with my son and my husband building forts out of driftwood or laughing with friends in the beautiful pacific northwest.

Global Account Director

I consult with our customers to understand their business aspirations and challenges before recommending a learning solution that is going to exceed their needs. I maintain close relationships to ensure they receive the best possible service. I work across all market sectors and levels; however, I'm particularly passionate about graduate development. Out of work, you’ll find me up a mountain attached to either a rope or a pair of skis.

Vesna andLorenc
Senior Consultant

I have been supporting people in communication for 20 years. Initially as a consultant and currently as a trainer, coach, and mediator. I am passionate about people and the complexity of human nature, and like to help tame this complexity for a specific purpose. Socially involved, I'm also a mother of three. Between all this, I find balance in meditation, yoga and nature.

Samantha andRostas
Global Lead

After 10 years leading the UK, I am now in a global role focused on two areas: one leading a people project, the other focused on marketing. I grew up through Impact as a marketer and love the buzz of building business through brand and storytelling. My other passion is the people and culture here, so this is the ideal combination for me. When I’m not working, I love spending time with my family, enjoying the outdoors and practicing yoga.
