October 27, 2021 - Estum Jiu-Jitsu, Tallinn, Estonia
4 year(s) 3 month(s) 13 day(s)
From January 2016 till now breaks and time off the mats in between but Jiu Jitsu is the only thing in my life that I have not quit. Promoted with two stripes 15.03.2023




January 3, 2016 - London/UK/10th Planet London - Tallinn/Estonia/3D Treening
5 year(s) 9 month(s) 24 day(s)
I started learning under Sean Harper and Jamie Scott. Unfortunately due to work and injuries I was only able to actually go to practice for about a year and a half in my 3 year period of living in London. I was able to compete twice in small comps. And it was one of the greatest parts of living in London for me. If anyone is over there I highly recommend going to train in their Gym. I had a long gap in my training of nearly 2 years before I came back to Estonia and started to train in 3D treening under Armin Pajula, Ronald Stimmer and Priit Mihkelson in May 2019. I have been pretty consistent since then and have recieved 3 stripes on my white belt so far.
