Heather-Jane Gray founded Synergy Transatlantic in San Francisco, California, USA in 1996, using her experience of large complex organisations to help clients lead change more effectively – focused on adding value by saving energy, time & money. As a Harkness Fellow at UC Berkeley, her post masters research into Values-based Leadership & Cultural Change, underpinned her work as a lone OD Practitioner across 47 different States (USA). She then partnered with Stephen Breese, an excellent facilitator, whom she met whilst working with Blessing White in California. He became our first Country Geographic Team Leader, followed by Anne Powell who was an Effectiveness Consultant championing our Health & Wellbeing (H&W) practice from Louisville, KY.

Looking to expand the team, Heather-Jane then returned to London to recruit values-based & experienced Effectiveness Consultants, Change Facilitators & ICF Credentialed Executive Coaches to serve clients across the Private, Public & Not-for-Profit Sectors.

In 2005, she moved to Melbourne, Victoria, AUS where we are now based - building our International Organisational Development (OD) practice with the help of a wide range of top talent from all walks of life. Over the years we've built a shared leadership model that gives robust consideration to decisions that impact the high quality of our client relationships & the Continuous Quality Improvement (CQI) of our services – making sure that they honour our clients with the added value that they deserve. Having always been interested in measuring the Quantitative & Qualitative impact of our programs, clients can be reassured of the Return on Investment (RoI). Within reason, we offer 100% Satisfaction with a money back guarantee from any first experience, if not completely satisfied.

Synergy Global prides itself on surviving & thriving for >25yrs & would like to take this opportunity to thank every client, procurement officer, team member, partner, supplier or mentor that has helped us fulfil our values-based vision of making a real difference.
