Dr Gifford Rhamie is the founder and Lead Executive Consultant of Rockstone Consultancy. He leads and curates a highly qualified agile team of specialists in culturally intelligent leadership and inclusive organisational practice. He does this by constantly asking the question, “What is the quality of your leadership’s culture?”


PEOPLE are the rockstones of your organisation. They live their gender, disability, sexuality, faith, and class through RACE.

Therefore, we will empower them to apply their best leadership so that their differences make for a vibrant and dynamic workplace – i.e., a welcoming, innovative culture of flexible solutions.


VALUE is the one asset that people carry beyond life. It is the values that are valued that form your culture.

We focus on unleashing and honing inclusive values so that your core business can thrive.


CHANGE is the constant of life. Yet, it can be difficult, especially when shifting culture, paradigms or the status quo.

Rockstone are adept at strategically managing cultural transformation in safe spaces throughout the organisation to enable curiosity, accountability, innovation and impact.

“I thought I spoke openly to all residents, not realising that I shied away from topics such as faith, which was important to them. I’m resolved to engage more professionally with people of faith by first listening.”



“The key for me was that Gifford and his colleagues ensured a safe space to talk.”

Michael, Deloitte
