Training Manager NASM CPT UCSD Certificate of Fitness Instruction/Exercise Science UCSC BA Neuroscience and Behavior TRX Group Suspension Training Total Gym Gravity Certified Trainer

I started my fitness career after 3 years in the medical field. After working as a medical assistant I couldn’t ignore how many of our patients were being pushed drugs or surgeries as their only option when preventative medicine, a healthy lifestyle, and nutrition were not even discussed. After years of keeping this frustration inside I quit my job and went back to school to become a personal trainer.

A few years later, I am a NASM certified Personal Trainer with experience training a wide variety of clients including new/returning exercisers, active older adults, post surgery, those seeking weight loss/muscle gain, and advanced weight training. I take joy in my job and feel honored being allowed to be part of your health journey.

I have always had a passion for and been actively involved in a fit lifestyle. I was a competitive swimmer until age 20 and since then have kept busy with weight lifting, yoga, swimming, and the occasional 5k. It is not just something I preach to those I am training - I strive to lead by example and show my clients that with hard work, a positive attitude, and the right nutrition and exercise for your body, any goal is achievable!

When I’m not at Fitness Together, you can find me getting my own workout in, hiking with my boyfriend and our two dogs, or exploring San Diego’s amazing restaurant scene!

NASM CPT, Exercise & Holistic Lifestyle Coach C.H.E.K Institute

For me, coaching others to achieve their fitness and well-being is a personal and professional passion. My love of movement began at a young age and has continued into my adult life. I’ve played many different sports and activities including: baseball, football, Jiu Jitsu, and Olympic weightlifting. As I got older, I realized that I could emulate the same movements I loved so much playing sports, in the gym in what we call “functional exercise”. This gave me the freedom to move however I wanted without the limitations of playing a sport.

My passion for being physically active also led me to working different jobs prior to becoming a personal trainer. Some of the jobs include working as an emergency medical technician, landscaping, working on boats, and being a surf instructor. I’ve found that my experience in these different fields has benefited me as a personal trainer.

I am a certified (National Academy of Sports Medicine) Personal Trainer and a certified Exercise Coach and Holistic Lifestyle Coach through the C.H.E.K. Institute. In my free time, I like to be outside connecting with nature; hiking with my dog and close friends.

Improving one’s fitness and well-being through exercise is a lifelong pursuit that should be dynamic, effective, and fun. In addition to movement and exercise, I coach my clients on optimal nutrition and lifestyle practices. It is an honor to work with my clients to help them achieve their health and fitness goals.

Certified Personal Trainer, Masters in Sports Management, BS in Exercise and Sports Science USF

Growing up, I have always lived an active lifestyle. I was a company Polynesian dancer for 14 years, and I competitively participated in Varsity sports throughout high school. Although I've been active my entire life, I didn't discover my passion for fitness till college, where I attained my Bachelors in Exercise & Sports Science at the University of San Francisco. Upon graduation, I landed a position as Rehabilitation Aide at Sharp Healthcare. For 5 years, I worked in both inpatient and outpatient settings, treating patients with various ailments and injuries. During my time with the Sharp Experience, I had the decision to either pursue a masters or doctorates. Interested in the business side of sports, I decided to return to my alma mater to get my Masters in Sport Management. With my second degree, I was given the opportunity to work in the sports and entertainment industry. There, I worked in marketing and public relations for large companies, such as Creative Artists Agency and Octagon. Although my time in the sports and entertainment industry was exciting and humbling, I could not ignore my passion for fitness. I saw how damaging working a sedentary job can be to the human body first hand. My coworkers developed back and shoulder pain. I even experienced lower back pain. Overall, I wanted to utilize my knowledge and experience from my time in the medical field to help relieve that pain. Thus, I quit my corporate job and returned to the health and fitness industry.
As a fitness trainer, I am a certified National Academy of Sports Medicine Personal Trainer and a certified Flexologist. I am committed to helping my clients achieve their fitness goals, whether that's to lose weight, become stronger, or to simply keep moving. I always approach my clients with a positive, empathetic, and enthusiastic attitude. But most of all, I always want them to feel comfortable and believe they can achieve anything.
When I'm not at Fitness Together, you can find me spending time with my family and friends. I love dancing, working out, reading, researching and learning various rehab/exercise techniques, and simply just being outdoors. But what I mostly enjoy as a San Diego native is discovering hidden secrets in the finest city in the world, such as exploring beautiful hikes, swimming in the ocean, experiencing new dishes at farm-to-table restaurants, and visiting historical sites.
