You may have seen Don and Ann walking their Black Labrador, Silky, around town. In addition to enjoying the delights of Del Mar, Don and his family enjoy camping, hiking, fishing, gardening, and dining with friends. Don also enjoys commuting to work on his motorcycle, which he rationalizes as the most fuel efficient transportation short of a bicycle.

Don is a firm supporter of the Del Mar Community Plan and believes in building consensus through full citizen involvement. He welcomes the opportunity to give back to this community that has provided such a delightful place for his family for the last 23 years.
