 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!

Lucy Lapane Trainer Holly Roser Fitness Studio

Fitness has been my passion for nearly 15 years. After 10 years of figure skating competitively and 5 years training in CrossFit/Olympic Weightlifting, I discovered my true calling in life is helping other people discover the life-changing benefits of exercise! Being able to share my passion for fitness and movement is truly a gift and I can’t wait to help YOU discover it! My goal is to make you feel strong and beautiful in the body you’re in. I hope to provide you with knowledge in fitness and nutrition to truly transform your life. I look forward to working with you and I’m beyond excited to be a part of the Holly Roser Fitness team!

Ursula Lochner-Bravo Trainer Holly Roser Fitness Studio

Depressed, overweight, and constantly injured, my fitness journey started when I was 18 and finally ready to make a change. I lost weight and grew in strength and confidence when I began powerlifting in college. The new routine and results impacted me so tremendously that I realized I wanted to pursue fitness even further, and switched my major from Political Science to Kinesiology. 


I continue to dedicate my time and involvement in sports, nutrition, fitness, and preventative medicine after college, and as a Bay Area native, I enjoy hiking, backpacking, skateboarding, and swimming in the area. 


Today, I bring my personal experience and journey with me to help you with yours, whether your goal is to become stronger, more confident, to lose weight, or just to feel better. Let’s get active!

My training helps anyone seeking muscle growth, fat loss, and general improved health for injury prevention. I am a Tracy-area native, and I enjoy hiking, surfing, and kayaking locally when I'm not working with clients. I look forward to working with you on your specific fitness journey!
