Meet Our Team


Denise Scott-Lister

Managing Director

As a business leader, I am an ardent believer that the workplace should be a place where people grow, develop and thrive. In my own efforts to live this out, I have twice led a business to be a finalist in the “Best Places to Work in New Zealand” (small business category). I have been involved in education and training for more than two decades and frequently travel overseas to learn from the leaders in their field. In the past 2 years alone I have trained with Tony Robbins, Dr John Demartini, Scott Harris and Keith Cunningham. Based on the belief that, in all areas of life, the recipe for success is consistently 80% mindset and 20% tactics, I work hard to ensure our training places as much emphasis on personal development as professional development.

Sharnell Stevenson

General Manager

Having spent 18 years as a leader in the service industry, I am passionate about growing people. My background is in large format retail management, specialising in team leadership, marketing and customer experience. I’ve been privileged to see increased store culture, consistent year-on-year sales growth and professional development of the people I lead. I love to use my business experience to increase performance and productivity in the organisations we serve.


Toni George

Training Co-ordinator
Being part of a team who help grow and inspire people to succeed in their work and personal life is really exciting. My previous work experience has been in event management and promotions for several years as a Marketing Manager in a big box retailer and I have also held several leadership roles. My organisational skills are one of the main attributes I bring to the role as Training Coordinator to ensure the smooth running of all programmes we deliver.

Carryn Wilkins

HR & Finance

I have 16 years of prior experience in Operations and Administration roles, working predominantly in London for large corporates and banks. Now living in NZ, I love being in Whanganui not only for the lifestyle but also for my role at Proven Performance. Working and supporting a great team whose passion is to grow and develop individuals and elevate performance. My role at Proven Performance is predominantly Accounts and Finance and I also am responsible for the HR Administration.
