From injuries and setbacks to weight gain and burnout, I know firsthand how challenging it can be to achieve your fitness goals.

But despite my own struggles, I’ve learned a thing or two about what it takes to overcome obstacles and achieve sustainable, long-term results. Through trial and error, I’ve gained the knowledge and expertise to help others do the same.

I take a personalized approach to training and nutrition coaching that meets the unique needs of each individual. I understand that no two fitness journeys are alike, and that’s why I offer programs to help you do this on your own and create customized programs that are tailored to your goals, preferences, and lifestyle.

What started as an in person gym in Southern California, Redefining Strength has expanded online to work with people all over the world and I’m proud to have been featured in Women’s Health, Self, Insider, and voted a top home workout by The Guardian.

I pride myself on being more than just a ton of certifications. My knowledge is based on real-world experience, dealing with real people just like you. I understand that fitness can be a daunting and overwhelming journey, and that’s why I’m here to make it easier and more enjoyable for you.
