The family thanks Ambercare Hospice and Professional Case Management for their caring support in the last few weeks. A memorial is planned for 3 p.m. June 23 at Fuller Lodge, followed by a reception. In lieu of flowers, the family suggests a donation to your favorite music or science education-related charity.
