is a full-service planning firm based in Honolulu, Hawaii founded in 1990 by John P. Whalen, then President of the company. Originally named Lacayo Planning, Inc., the firm operated through 1994 as part of the Lacayo Group – a multi-disciplinary architecture/planning/ design corporation. Renamed PlanPacific, the firm became independent in 1995.

PlanPacific is well experienced in Hawaii’s regulatory system and specializes in assignments that require a sophisticated understanding of the public interest.

PlanPacific intends to remain a small company so that (1) every project receives the personal attention of the company’s principals; and (2) PlanPacific can team with the professional experts required to meet the specific needs of each engagement.
