When the new Planned Parenthood Shasta Pacific facility in San Rafael facility opens its doors this summer, the two-year-old Mill Valley Planned Parenthood will be closing, as much of the staff head to the significantly larger San Rafael building. Local leaders and Planned Parenthood staff and supporters gathered Monday in San Rafael’s West End for a sneak peek of the new center, which organizers hope will open in early June. The soon-to-be full-service facility, at 2 H Street, may create déjà vu for some community members. The 6,632-square-foot building housed a Planned Parenthood clinic in the past.
