I enjoyed recreational softball from the age of ten through my early thirties. It was in my early twenties when I first found my love for Olympic weightlifting and became an ACE certified personal trainer and amateur weightlifting competitor. For over 20 years now, I actively volunteer as an American Red Cross Instructor for an array of courses and umpired fast and slow pitch softball for nearly 15 years. In college I played rugby and dabbled in bodybuilding between competition cycles. I moved from my hometown in Ohio to San Diego and while I grew professionally I placed my health and wellness low in my priorities for a few years. After putting on a considerable amount of weight and finally having enough of a sedentary lifestyle, I found CrossFit through a friend at work. Since starting my journey with CrossFit in late January 2013, I have lost over 100 pounds of fat, gained a considerable amount of lean muscle mass and enjoy a level of fitness I’ve never before known. I am a believer in the combination of functional movement, mobility exercises and informed nutrition. I adore witnessing people literally change their lives in so many ways through the influence and commitment to CrossFit. I am grateful and thankful for our CrossFit Community and I appreciate the opportunity to share it with others…see you in the box!

  • All things Yoga

Yoga is my passion and has been a part of my life for over ten years. My practice has helped me grow stronger, more flexible, and fearless, both on and off the mat. Yoga inspires me to live each moment more mindfully and with intent. I always have been active and played sports. Yoga helped me transform my body to reach my optimal physical well being. I love teaching this practice to others. It enables me to share my love for yoga with others so they can experience the benefits of this practice for themselves. I strive to have every person who leaves class feeling relaxed, renewed, and strong.

I have always been an athletic person. Growing up I played travel/competitive youth baseball, which led to 4 years of varsity baseball, which led to 4 years of varsity baseball and 2 years of varsity basketball in high school. I choose to play college D-1 baseball, despite being drafted by the Padres right out of high school. I played at UCLA and LBSU. After a career ending injury, I lost interest in working out. It wasn’t until 2013, when I was introduced to CrossFit, that it sparked my competitive nature again and I got my L1 in 2014, followed by my Kids’ CrossFit Cert in 2016. I love coaching and I enjoy that my entire family can participate in CrossFit. My hobbies include woodworking and Search and Rescue with my dog. The one thing I love about Polarize CrossFit, is the family atmosphere we have here.

  • CF-L1 Coach

Growing up I was always active. In first grade I began playing little league basketball and played every year after. When I reached 4th grade I started to play volleyball which became my overall passion and eventually I began running track. I loved sports then and even now you can catch me playing beach volleyball, soccer, and basketball. I love hiking, exploring the outdoors, and anything that keeps me active.

 I always thought I wanted to be a personal trainer. I enjoyed working out and wanted to help others enjoy it as well. It wasn’t until I started an internship at Polarize CrossFit in January of 2020 that I became involved in CrossFit and realized how much I loved the group dynamic and their idea of working out. Being a part of a group of athletes that worked towards the same goal was astounding. I saw their motivation and it occurred to me how much I wanted to be apart of the CF community to help each and every one of them, as well as myself. I want to help everyone and anyone who comes into the gym to improve their overall health, both mind and body. CrossFit has been a second family to me and I look forward to growing that family as a new CF-L1 trainer!

I have been playing sports both recreational and competitively since I was in elementary school. I played soccer competitively in high school and spent a short few months on my college track team training with decathletes. Shortly thereafter I found an interest in weight training and bodybuilding. That interest then evolved into powerlifting, which became the focus of my training for several years. During these first few years of training, I found myself driven to learn as much as possible about diet, training, and consistency as I could.

After moving to the San Diego area for a job teaching high school physics, I found that my consistency in the gym had been diminishing. In comes CrossFit to the rescue! I originally chose to give CrossFit a try purely because of the scheduled class times and their ability to give me some much-needed consistency to my workout routine. Fast forward two years and I am doing CrossFit four to five times per week, still setting personal bests, and getting my CF-L1. It is my goal as a coach to help every athlete that steps through our doors to improve their fitness, mindset, and approach to living a better life.

  • CF-1L Trainer
  • Marine Corps Martial Arts Instructor

Since I was young, I have always been active. I have always loved playing sports and being active. I played various sports such as football, basketball, soccer, and wrestling throughout my life. Right after I graduated high school, I joined the Marine Corps. I began to really focus my attention into lifting weights in mid-2015. Starting out, I did the same thing that most people do and messed around with various styles of working out. I found the most interest with powerlifting, which I did for a few years. In 2019 my wife, Sara, convinced me to try CrossFit for the first time. From the first day I tried it, I fell in love with the community and the culture.
