My Specialties

Over the years, I've continued my education in areas that reflect the clients I work with and the different needs I encounter as a trainer.

Women's Fitness

I work with women across different stages of life, including women who want to build strength and mobility, prenatal and postpartum clients, and women returning to or beginning exercise.

Senior Fitness

I work with older adults with a wide range of exercise experience—from people who have stayed active throughout their lives to those beginning strength training later in life. I've also worked with clients following joint replacements and physical therapy.

Corrective Exercise

My corrective exercise education helps me assess movement and recognize areas where strength, mobility, balance, or movement patterns may need additional attention.

I use that information to help determine which exercises and modifications make the most sense for the individual.

Stretching & Flexibility

I incorporate stretching, mobility, and flexibility work when appropriate to help clients move well and support the activities they enjoy.

Behavior Change

My background in psychology and behavior change has shaped the way I coach. Exercise isn't just about knowing what to do—consistency, confidence, habits, motivation, and finding something you actually enjoy all matter.

Clients I've Worked With

One of the things I've enjoyed most about my career is getting to work with people with very different backgrounds, abilities, and goals.

Over the years, I've worked with:

  • Pregnant and postpartum women
  • Older adults, including clients with joint replacements
  • People returning to exercise after completing physical therapy
  • Clients with scoliosis, spinal stenosis, osteoporosis, and other considerations
  • Runners → of different experience levels
  • Military Personnel & PFT Training →
  • Recreational athletes
  • People returning to exercise after injuries or extended periods of inactivity
  • People working toward weight-loss and body-composition goals
  • Adults who want to become stronger, improve their mobility, and stay active

My Background

How I Got Into Fitness

My passion for fitness began in middle school through cross country and track, where I discovered a love for running. As I got older, however, I developed scoliosis and began experiencing pain during and after runs.

That experience led me to explore yoga and Pilates and ultimately changed the way I thought about exercise. Instead of focusing only on running, I began learning more about strength, mobility, movement, and how different forms of exercise could work together.

Becoming a Pilates Instructor

Before heading to college, I decided to become a certified Pilates instructor, without realizing at the time how important that decision would become to my career.

I completed a 500-hour Pilates apprenticeship under Julian Littleford of JL Body Conditioning and began teaching Pilates.

While attending the University of California, Santa Cruz, I taught at multiple Pilates studios while earning my B.A. in Psychology. I originally considered pursuing a career in therapy, but eventually realized that what I really loved was helping people through movement and exercise.

Expanding Beyond Pilates

After college, I returned to San Diego and continued working in Pilates studios.

As I gained experience, I began to realize that Pilates wasn't necessarily the best or only tool for every person or every goal. Some clients needed more traditional strength training. Others needed mobility, balance, cardiovascular conditioning, or a combination of approaches.

I became a certified yoga instructor through YogaSix and later a NASM Certified Personal Trainer, which allowed me to broaden the way I worked with clients.

Over the years, I've continued my education in corrective exercise, women's fitness, senior fitness, stretching and flexibility, and behavior change.

I still love Pilates, but I also love having the freedom to pull from different forms of exercise depending on the person I'm working with.

I am also currently attending massage therapy school and plan to add massage therapy to my professional toolkit. I’m excited to continue expanding the ways I can support clients by combining my background in movement, strength, Pilates, mobility, and hands-on bodywork.

Opening Fit Monkeys

In 2015, my mom, Denise, and I opened Fit Monkeys.

After years of working in different gyms and Pilates studios, we wanted a place where we had the freedom to work with clients individually instead of feeling tied to one particular style or method of exercise.

Fit Monkeys gave us the opportunity to combine our different backgrounds and create the kind of studio we wanted to work in: small, personal, welcoming, and centered around the individual.

Outside of Fit Monkeys

Fitness is also a big part of my life outside of work. Running has remained one of my favorite activities, and I've continued distance running throughout adulthood.

When I'm not working, I also enjoy:

  • Distance Running
  • Hiking
  • Front-End Web Development & Coding (HTML, CSS, JavaScript)
  • Drawing
  • Writing
