 Alyssa VandeZande Trainer Holly Roser Fitness Studio San Mateo

Born from a history of long, snack-filled hikes with my parents as a child, my passion for fitness grew from the feeling of connectedness, gratitude, and calm that came from “sweating it out.” These three senses are now the pillars in my approach to helping others in their fitness journey. As a Certified ACE Personal Trainer and cycling, HIIT, and cardio kickboxing group fitness instructor for the past 8 years, I use my experience to work closely and carefully with my clients on their unique needs and goals. My hope is that you will experience the same senses of connectedness, gratitude, and calm from working out as I do. Let’s sweat it out!

As an athlete and dancer, my goal is to help others feel good through movement. I have a Bachelor of Science in Kinesiology from Pennsylvania State University and I have worked professionally as a holistic wellness coach, exercise specialist, and fitness director in the health and wellness industry for nearly a decade. 

Working with others to create customized solutions for improved health, both mentally and physically, is my mission. Using a comprehensive approach to wellness, I strive to teach people how to address all aspect of their health—from their physical body, diet, and habits to their spiritual practice.

Karissa Bollinger

Master Trainer

I’m an ACE Certified Personal Trainer with a degree in Kinesiology and a minor in Nutrition from University of Central Arkansas. My mission is to provide you with the tools to achieve success and see real results.  

My interest in movement and nutrition was sparked by my love for soccer at a young age. Dedicating myself to a sport and becoming an athlete inspired me to continue in that direction and obtain a degree in Kinesiology and Nutrition. This provided me with the foundation I needed to be able to help people achieve their dreams. 

I’m fueled by my passion for helping others reach their fitness goals and change their habits. There’s no greater reward than to see someone exceed their own expectations. I’m confident I can help you reverse the aging process and have fun while doing so!

Master Trainer

My passion for helping women reach their goals was sparked by my experience with trapeze. As I had moved to a new town and was looking for fresh ways to stay strong and fit, I discovered a gym that offered trapeze classes. It was there that I had formed new healthy connections with like-minded women who were also just trying to honor their fitness. 

 

I then went on to obtain a NASM Personal Training Certification, followed by a certification in Health Coaching. From 30min intensive bootcamps to one-on-one personal training, I’ve been blessed to find a job that is truly fulfilling and I can’t wait to share my knowledge to help others.

I grew up being very active and trying out as many sports/activities as possible; with dance and tennis being favorites. I was always interested in exercise and biology and anatomy, so it was a no brainer for me to study Exercise Science.

 

I went on to become a NASM certified Personal Trainer because I thoroughly enjoy help others achieve their fitness goals and seeing their confidence grow

along with it. I am also a certified Health Coach through the Institute for Integrative Nutrition, because fitness and nutrition go hand in hand, and helps to have someone who can guide in both areas.

I am currently going back to school for Neuroscience because I want to research how exercise impacts the brain, not only from a structural standpoint, but how it can affect mental health as well.

When I am not at the gym I can be found with a good cup of coffee in my hand, reading, hiking, wine tasting, cooking or going to concerts!

Growing up in Italy, the outdoors and being in nature has always had a special place in my heart. My passion of encouraging clients to make healthy and sustainable lifestyle changes is because of this.   

As a strength coach, I’ve had the privilege of helping people from all walks of life achieve their dream results. After becoming a Certified Personal Trainer with the National Academy of Sports Medicine, I gained valuable experience working at a body-building gym and learning the methods for achieving specific aesthetic and physique-related goals.

 

Further, my corrective exercise specialization, coupled with my undergraduate coursework in kinesiology, has provided me with the tools necessary to address and correct muscle imbalances and tension. 

Let’s train away those aches and pains!
