About Us



    The Center for Positive Change was founded in 1995 in the north end of Napa Valley, California.  This vibrant and verdant valley is world-famous as a food and wine vacation destination, and is one of our favorite retreat locations. 

    In 2005, The Center for Positive Change office was relocated to Washington's Olympic Peninsula in the delightful town of Sequim.  The Olympic Peninsula is renowned as a vacation destination for hiking, boating, and fly-fishing with access to many unspoiled rivers, creeks, alpine lakes, and ocean shorelines.

   As in all of life, transition continues. In November of 2013 we expanded our services to include Jefferson County as well as Clallam County on the Olympic Peninsula. We moved our office location to the maritime setting of Port Townsend. We are honored to now serve those from the Eastern part of the Peninsula as well as those from the Western
