Strategic and Business Planning.

Change Management.

Learning and Development.

E.S. Tunis & Associates (ESTA) is a network of management consultants based in Ottawa, Canada. A Canadian incorporated company in business since 1991, we advise public and not-for-profit sector clients both in Canada and internationally. The firm has had experience leading consulting assignments in more than 100 different international, federal and provincial departments and agencies.

ESTA has three complementary core practice areas: Strategic and Business Planning, Change Management, and Learning and Development. We often engage in projects in which all three components are required to meet client goals. Our approach is one based on the principles of organizational development, requiring client participation in developing an understanding of the issues arising from our research, forming a collective commitment to a common future, crafting a strategy to move forward, and developing methods to track the results of tactical action to address organizational goals.

We are a medium sized, boutique consulting practice that specializes in customized solutions tailored to the needs of our clients. We combine proven expertise and best practice with innovative ideas and a collaborative approach to working with clients. We are dedicated to providing the best of three key elements to our projects – content, accessibility and price – to deliver value and customer satisfaction.

We leave the delivery of “off the shelf” products to big box consulting firms. We look for project opportunities that will showcase the creative skills of our team in the development and delivery of unique, high impact projects.

We work to build skills and competencies in our client organizations, leaving them equipped with a practical understanding of the tools we helped them develop. We excel at helping managers and executives focus on the right issues, develop the right solutions, and implement workable plans. We work best as advisors, trainers and facilitators, and our experience shows us that our clients prefer taking charge of their own destiny as early in the process as is practicable. This results in obvious financial economies and generates true buy-in to the product. Our goal in every intervention is to equip our clients with the knowledge and confidence required to carry out their functions without third party support.

We offer services in both English and French.


ESTA has over 25 years experience providing consulting services to Canadian public sector agencies, para-statal entities, not-for-profit organizations and special interest groups. We have provided our services to managers and employees at all levels-our clients have ranged from shop floor employees to professional and programme staff and leaders in the most senior positions of the federal government-including Deputy Ministers and Cabinet Ministers.


Over the past 10 years, ESTA and its associates have carried out assignments on 5 continents and in more than 20 countries. We have worked on-site in South East Asia (Vietnam, Malaysia, Thailand, the Philippines), Africa (East, West and Southern), Eastern and Western Europe, the Middle East, South America and China with organizations such as UNHCR, UNICEF, UNFPA, and the World Bank. We are sensitive to the challenges and opportunities in these environments.
