“I had a nice update from Trudy on your visit.    We are all very impressed with your work, and thank you for helping motivate our employees.    June 1st is National Cancer Survivor Day and as a member of the “club” I want to recognize you as a role model for cancer survivorship.  Have a great day!”



Wade Iwata – Director, Children’s Brain Tumor Foundation

“Greg has been a peer mentor for Children’s Brain Tumor Foundation for some time now. He has been an amazing support, mentor, and inspiration to families facing a brain tumor diagnosis. His dedication and compassion are evident in the relationships he has formed. Greg’s experiences and willingness to reach out are attributes we look for in our peer mentors and he has far exceeded many of our expectations. Thank you Greg for all you have done for the families we refer to you!”



Lisa Cristia – Match Specialist with Imerman Angels

“Greg is a wonderful caring man who has triumphed over many adversities.As a cancer survivor he provides his time and knowledge freely to anyboby who need him. He had never said no to helping any individual, caregiver or friend that need to talk about brain tumors. His tireless and selfless soul gives back to the community as a whole and anybody who had ever met him or talked to him, knows he is a solid, reliable, trustworthy guy.”


Boris Seletsky – Eisai Scientist

“Greg gave a truly inspirational talk, “Winning the Fight of Your Life” at our company’s Oncology Patient Reality event in December 2011. Nearly 150 people attended Greg’s presentation where he shared his experiences as a cancer survivor and a caregiver. Greg won his battle with cancer, and he uses his experience to help, support, guide, and motivate others. His presentation was well organized and delivered. Many people asked questions after his talk, and several of us attended a round-table discussion afterwards. Greg is a one of the kindest, most positive and inspirational people I have ever met.”
