About me

I’ve been in the industry since 2015 and have worked as a personal trainer in San Francisco and Portland. I’ve always been fairly active—I played soccer and ran track in high school—and have always liked to move. Exercise has been a grounding activity for me, and that’s something I want to share with others. After 20 years of bartending, I decided that rather than pouring people drinks for people, I’d prefer to teach them how do things that will better serve them in the long run. Though I’m not Buddhist, I like the idea of “Right Livelihood,” or making a living in a way that contributes to uplifting people. I enjoy personal training because I feel I am doing something positive in the world.

My ideal client is brave enough to walk through their own personal fears (I do this on a daily basis). Nothing gets me more jazzed than to see a client who was terrified of attempting a box jump actually do a box jump!


I specialize in getting my clients strong, conditioned and mobile. This applies to newbies, elite athletes and everyone in between. I use a variety of modalities to help clients become proficient at the six human movement patterns of squat, hinge, press, lunge, pull and carry. Additionally, I love incorporating HIIT for conditioning and utilize battle ropes, body weight and kettle bells to achieve optimal results. Lastly, I am a big fan of pre-hab exercises (or all those not-so-sexy exercises) that should be done (yet we all avoid) to make our big lifts even stronger.

I believe in the holistic approach of healthy mind, body and spirit. In addition to teaching clients the proper mechanics of a given exercise, the discipline that comes with a dedication to self-improvement applies to all aspects of life. “Civilize the mind and make savage the body” is what I’m constantly striving for, and I like to impart to my clients as well. I believe that the healthier our bodies are, the better we will be at making decisions and dealing with the stress. When we are stronger physically, mentally and emotionally, we can face the world with greater confidence and equilibrium.

Outside the gym

I am originally from New Jersey and lived in San Francisco for 20 years before moving to Portland with my wife. I enjoy training Jiu-Jitsu, being outdoors (I particularly love waterfalls), playing guitar and checking out comedians as a reminder to not take it all too seriously!
