In Memoriam
The GPTC mourns the loss of its Chairperson and friend Marti Marek. She is missed.
The family is asking that a donation to the Las Vegas Strip Kiwanis Foundation be made instead of sending flowers or plants. Marti worked with Kiwanis for over two decades performing community service to give back to the world we live in. Donations can be sent to P.O Box 55 Blue Diamond, NV 89004.
