Clients who've loved our HR programs and solutions.

The Centre for Workplace Leadership engaged A-HA to work on the Gender Equality Strategy project in 2015, a project for the Department of Employment. A-HA worked with our researchers during the interviews contributing questions and feedback based on their expert knowledge; and assisted in writing and editing the case studies. A-HA were a pleasure to work with and helped us meet a very tight project timeline. The support and expertise A-HA provided contributed to the success of the project and has led us to hire A-HA for a new project currently underway.

Our firm has been in operation for over 7 years and last year we reached a point where we realised we needed the support of an experienced HR professional. We reached out to A Human Agency initially for assistance on a project and a recruitment campaign, and were introduced to Simone as having a wealth of HR knowledge, particularly in law. We quickly learned how much support Simone could give to us and is now a valued member of our team as our People and Wellbeing Manager. She is always available when we need and sits with our Sydney team for ½ a day per week. Outsourcing our HR has been incredibly beneficial, we can’t imagine our business without her.

Rabobank has engaged with the services of “A Human Agency | A-Ha!” on several occasions. The Human Resources matters which A-Ha! assisted with was complicated to say the least. Through positive coaching A-Ha!, in particular Katriina Tahka played a significant role. Through Katriina’s professionalism and unique skill sets she was able to bring the people involved together in achieving the right outcomes for the individuals as well as the organisation.

A-HA provides the right combination of knowledge, experience and humanness to bring about real strategies for improving our capabilities to deliver on strategy.

In an industry that is evolving rapidly, and in an organisation with diverse roles and responsibilities, we needed a partner that could understand our challenges and opportunities and work with all of our people—including our Board, CEO, management and employees. This was specifically to support us on a Diversity & Inclusion program.

A-HA are genuine people who approach every person and every challenge with integrity, listening and understanding, while also using their expert knowledge to influence and lead everyone towards the outcomes we need for growth.

A-HA’s human-centred approach, coupled with their commercial acumen, makes them a go-to for any organisation seeking to improve their business through real Diversity & Inclusion.

A-HA was able to provide a pool of skilled facilitators, who demonstrated their subject matter expertise whilst delivering 39 sessions across 29 locations at extremely short notice. Due to our extensive regional footprint, it was imperative that the facilitators understood the varied and often complex operating environments for each of our regions, which A-HA were able to demonstrate a flexible approach which drove consistency across the program roll out.

My first impression of Katriina was someone who immediately puts you at ease, is non-judgmental,  able to get a quick sense of your needs and then provides the right direction. She has a great capacity to convert theoretical concepts or complexity into very practical and tangible outcomes. For example, when we were developing our Diversity communications strategy, Katriina provided guidance which helped re- shape the work into a simple and effective framework.
