While in the ER for pneumonia the doctors found tumors (hes been battling back and forth during his service with cancer since 2011) have spread to his organs and all of his back. It's no longer treatable. If youre able to donate, it can help this United States Marine who has fought in the middle eastern conflicts and gave many years of service to the United States of America and those who have the privilege to call themselves an American. It is thanks to people like MSgt O’Brien. This man, this Marine is and will always be a true leader and inspiration to those around him. Always leading from the front, never complaining, never letting anyone feel sorry for him. This gofundme is for him and his family in hopes of improving quality of life and help with payment for any medical care he may need assistance with. if able to, take some time to give what you can and spread the word of this Marine in need, thank you.
