Thought Leadership

Kellen established thought leadership in the European association environment in many ways: Leaders of Kellen are active in the European Society of Association Executives (ESAE). Alfons Westgeest and Maria Teresa Scardigli served as Board members. Alfons was also Board member of the American Society of Association Executives (ASAE). Nele Devolder is a board member of SEAP, the Society of European Affairs Professionals.

Kellen has demonstrated leadership in Brussels through educational activities such as its annual EuroConference (2000 –2016) as a platform for association executives and companies to learn and share best practices on association management.

Kellen shared its knowledge through three books published by Palgrave on association representation and advocacy (2000 –2003), executive lunches and workshops.

The Report on Strategic Planning for Associations (2014) is a reference work. Social Media Reports 2013, 2014, 2015, 2016 (Europe, US, China) illustrate our forward thinking on important factors for associations regarding social media, based on a wide field research project.

For over 10 years, Kellen partners with ASAE, the American Society of Association Executives to host a yearly conference in Washington DC: ‘Europe Today’.

Kellen is also an active supporter and contributor of ESAE and FAIB in Brussels.

Testimonials and why clients like to work with us

“We find Kellen highly professional, dedicated and efficient, worthy of their good reputation. The flexible approach to association management services suits our organization, and we benefit from the continuity and in-house synergies of a global company.”

Yves Goemans,  DuPont, Chairman EUVEPRO (European Vegetable Protein Association)

“Kellen played a crucial role in the set-up of VIPA International in 2014. Thanks to their professionalism and expertise in building consensus the association was created in less than one year time. The first facilitation session was instrumental in getting the go-ahead from all the parties around the table to create an industry representation as a way of tackling some regulatory and technical challenges which were preventing the growth of the VIP (vacuum insulation panel) industry. Since then the association has grown in membership, activities and visibility and we have good prospects ahead of us. As President of the association in the first two years of activity, I was grateful for having the support of Kellen’s staff and I am sure the other Board members concur with me in saying that we could not have made it without them, at least not as fast and effectively as we did!”
