I am passionate about optimizing your health in order to unlock your full potential.  Whether it is through choosing the best ingredients for a healthy meal, breathing effectively during a workout or calculating the correct amount of sleep, I have dedicated my time and career to finding the life hacks that turn today’s crazy world into an exciting playground. In addition to being a NASM-Certified personal trainer, my years of experience as a yoga teacher and health coach allow me to tackle your challenges in a holistic way. This approach helps my clients grow stronger, both mentally and physically, while staying balanced and nourished. 

I am both proud of and humbled by my own personal health journey. Originally from Brazil, I grew up living a very healthy lifestyle. However, things changed shortly after I moved to the United States and began to focus intently on a demanding career in finance at a top tier Investment Bank. Year after year, I prioritized my job performance and success in the corporate world over my own personal health and soon developed chronic pain and food allergies. I was too stubborn to believe the doctors who told me I was doomed to spend the rest of my life in an unhealthy body.  I became obsessed with digging deep into the inner workings of the body and how to achieve optimal health. Through extensive injury prevention research, I have healed my own ailments and am determined to revolutionize how people perform as athletes and professionals in their everyday lives.

On weekends, I enjoy the Bay through hiking and taking photos of its natural beauty. When I'm not coaching clients or organizing retreats in Latin America, I spend my free time traveling the world and spending time with my family in Salvador, Brazil.

I have been working with Mari for over 1.5 years and can confidently say she has helped get into the best athletic condition of my life.

I initially started working with her because I wanted to evolve my strength training but became quickly amazed at how her focus on form, breathing, and nutrition have pushed me to another level. I used to think the formula was all ‘no pain, no gain’ - yet her focus on new habits (like dynamic stretching and yoga) helped me recover faster and perform stronger.

As a busy professional, I appreciate how each workout is carefully thought out; she is all about personalizing the experience and I can see the results. I cannot recommend her highly enough!

I have worked with Mari for many years. As a person, she is a truly awesome human. She cares so much about others and clearly has a calling to help people. You will feel this the minute you meet her.

She is so passionate about fitness, yoga, and health. She helped me create a more balanced state in my life and in my fitness routines. She helped me fine-tune my yoga practice as well as create a fitness routine that fits my current needs. I am a working momma so my schedule doesn’t allow me to do be at the gym/yoga studio as often as I once was. She also helped me get my eating back on the right track.

Mari will work with you and help you reach your goals. She will listen, she will care, and she will be your biggest advocate. Work with her, it will be one of the best decisions of your life!

Mariana is one of the most driven people I’ve come across in the fitness world - and that’s saying a lot! She is an excellent instructor and genuinely cares about the success of her clients. Her fitness level itself is motivation. And you know she can guide you in rehabilitation exercise all the way to advanced workouts due to her own fitness journey and expertise. She’s vastly knowledgeable in technique, nutrition, and recovery. I’ve worked out with Mariana in both the gym and the yoga studio and can attest that her workouts will get you to the next fitness level if you stick with it. I highly recommend!
