About
Olivia began working as a personal trainer while completing her master’s in mental health counseling and quickly discovered how deeply connected the two fields are. She found that many of the same principles—goal-setting, behavior change, resilience, and self-awareness—apply in both the gym and the therapy room. That insight now shapes everything she does.
With a background in team sports, distance running, and weight training, Olivia brings a wide range of experience to her training sessions. She helps clients view fitness not just as a way to get stronger, but as a meaningful part of their overall wellness. Her approach is informed by the latest research and grounded in real-world results.
Whether you’re just getting started or training for something specific, Olivia will work with you to develop a fitness routine that feels fun, sustainable, and empowering—one that fits your life and supports your goals. For her, fitness is a place where people can practice control, see progress, and build the kind of habits that carry over into every part of life.
