I’ve been a community volunteer for many years now. Whether it’s building homes for low-income families, gathering back to school donations, or supporting my local pet adoption center, there is always work to be done. Having years of experience in project management, I’m able to apply those skills to my volunteer work to help others whenever possible.
I’ve been involved with Check for a Lump for several years now and I have met some of the most incredible individuals. The strength and perseverance these ladies exhibit is extraordinary. The stories women tell me about their journey is humbling. And the caregivers, selfless and loving.
It’s important that we continue to make an impact in the fight against breast cancer and for me to be an active participant in that fight.
