We are Maguire

After 9 years with a renowned firm in The Hague, Patrice van Oostaijen founded Maguire Tax & Legal in 2006. The goal: an informal and honest practice for advise & accountancy, with fast and efficient counselling at high level and modest rates. The name Maguire stems from Tom Cruise’s character in the movie Jerry Maguire; on the one hand because of our specialism in advising sports agents, and on the other hand because the similarities in Jerry Maguire’s pursuing his own dreams. After being located for 10 years in the famous P.C. Hoofstraat in Amsterdam, we decided to move office to the Jan Luijkenstraat in 2017.

Maguire’s first employee in 2006 was Erik Jan Peffer; 10 years later he became co-owner. We are currently a boutique firm with 12 special and dediciated professionals. Every day, behind the screens, these professionals discuss the clients’ positions in order to ensure efficient and optimal service.

Since 2006, we have grown steadily every year, although growth in itself is not our goal; that goal will always remain to supply our clients with optimal care and to build relationships for life. Please be welcome!
