Johan Arnold Haggren was born on June 28, 1945, in Stockholm, Sweden, to Arnold and Britta (Hallman) Haggren. His professional life developed in Stockholm and neighboring Solna, within Sweden's public legal administration and private business-law sector.
He has two children, Joakim and Charlotte. English was among the languages he spoke in his professional life.
Haggren studied law at Stockholm University and received the juris kandidat, or Bachelor of Laws, in 1969. Stockholm University's Faculty of Law began in 1907 as part of the former Stockholm University College and was established with strong links between academic legal education and practical legal life. It later developed into Sweden's largest law faculty, combining legal education and research across the field.
His legal education preceded service in Swedish courts, public administration, and private practice, giving his career both a public-law and commercial-law dimension.
Haggren began his professional career in Swedish courts, where he worked as a lawyer from 1970 to 1972. He then became department head at the National Tax Board in Solna from 1973 to 1976. The National Tax Board formed part of Sweden's central public administration, administering the country's tax system during a period of expanding welfare-state institutions and increasingly complex economic regulation.
From 1976 to 1982, Haggren was an associate at Advokatfirman Lagerlöf in Stockholm. In 1982 he joined Advokatfirman Cederquist, becoming a partner and remaining in that role until 2004. Cederquist, founded in Stockholm in 1953, developed into a major Swedish business-law firm with expertise across commercial legal practice and an international client base.
From 2005 onward, Haggren worked as a consultant at Advokatfirman Cederquist. His career therefore extended from judicial and tax administration into private legal practice, followed by continuing advisory work at the same firm.
Haggren was a member of the International Fiscal Association and the Swedish Bar Association. The International Fiscal Association, founded in 1938, is an independent international organization devoted to comparative and international fiscal law and the economic aspects of taxation. The Swedish Bar Association, founded in 1887, promotes professional and ethical standards in Swedish legal practice; under Swedish law, the title advokat is reserved for its members.
Haggren is the son of Arnold Haggren and Britta (Hallman) Haggren. He has two children, Joakim Haggren and Charlotte Haggren.
