After two days of candidate filing, there’s already a crowded field to replace Don Jacobson on the Board of Commissioners for Public Hospital District No. 1.

Jacobson of Renton will not seek a fourth term on the board, which currently oversees the operations of Valley Medical Center.

As of Tuesday evening, the field includes Mary Alice Heuschel, Chris Clifford, Jim Grossnickle, Paul Joos and Michele Fisher.

Heuschel is superintendent of the Renton School District and has attended a number of board meetings where a strategic alliance between UW Medicine and Valley Medical Center was discussed. She had indicated in early February at one board meeting that she wished to serve as a commissioner.

Clifford of Renton has run for a number of elected positions in the city. His attempts two recall Jacobson in 2008 and commissioner Carolyn Parnell this year failed.

Grossnickle is a research scientist who lives in Newport Hills in the northern part of the hospital district. He ran unsuccessfully for the Renton School Board in 2009.

Joos is an ophthalmologist who founded the Valley Eye and Laser Center more than 30 years ago.

Filing for the November general election began on Monday and finishes late Friday afternoon.
