On behalf of Mas Guru Dennis Ocampo:

It is with a heavy heart to announce our Grandmaster Mas Guru Greg Alland has passed on April 13, 2020 away.
As we continue to train and practice his Art of SinaTirsiaWali Kali that we Rememeber him every time we share or practice a skill that was taught personally from him to you or from me to you. We will continue to pass on his legacy of SinaTirsiaWali Kali and continue to share HIS art to those who want to learn.
For those who trained with him, we will truly miss his incredible skill that we saw with our own eyes and his passion for the Filipino Martial Arts.
For those who never got to train with him or meet him, I truly wish you did. Many of my words are direct quotes from him when I was training under him that I pass on to you as well as his teachings. 
As I made my promise to him, I will make his system stronger then its original through words and skill. As I  want you all to know that I expect the same from you as you pass on to future students.
 Always rememeber as Guru's, train your students to be better than you as Mas Guru always wanted me to be better than him. This way SinaTirsiaWali will only get stronger for generations to come.
If you know the 64 attacks that he taught, at some time that you may have, take 64 seconds of your time for a moment of silence for "OUR" teacher... Mas Guru Greg Alland.
