My name is Joceline Santiago. A lifetime passion of mine has been and will always be fitness.  I have found fitness helps one feel empowered and strong and in many ways provides a therapy to help navigate life's challenges.  My desire is to be able to work with clients as their coach helping them to achieve fitness goals and to be able to reap all the benefits that being strong, fit and confident all of which healthy fitness habits can provide. 

I am super excited to share that with my community.

A little bit more about me.  During my 6-year military career I was an instructor for the physical-test that the military would administer; and it was there that it stood out to me that most soldiers did not have the proper care during their service when it came to stretching, strengthening, mobility or balance. Especially for those of us that were injured including myself. I made it my mission to fully understand the body and its mechanics in order to be able to help those in need.

I decided to take my Bachelor's degree in Human Biology.  After the military I dabbled in various ventures, but I came to the realization that I was always drawn back to fitness. I decided to take a fitness certification specializing in active aging to not only help with the aging body, but to understand injury recovery and rehabilitation. I came full circle and I have since been training many people of every age group for the past few years.  I’d love to help you reach your fitness goals.


​Joceline works wonders!

When I first contacted All In One Fitness about a personal trainer, I was looking for someone in my age range because I wanted a trainer who understood health and fitness around menopause. Joceline reached out and we had a great talk about what we could both bring to the teamwork. I was initially concerned about our age difference but quickly realized that with Joceline – it was not going to be an issue.

Joceline is open, honest, professional, kind, knowledgeable, focused and totally committed to her clients’ progress.  She doesn’t pretend to know everything – she does her research - which makes me trust her all the more. She listens and then adjusts our training on the spot or makes a different plan for our next session… Joceline is creative, lighthearted, solution oriented and tough!

Which leads me to my favorite thing about Joceline – her attitude: I’ve had several surgeries over the years and some movement is restricted, Joceline never lets that stop us, she has lots of techniques and ideas in mind and says, “There’s always a way!” I leave every session with Joceline feeling great – stronger, more focused and energized. Thanks Joceline!

Working with Joceline has been an incredible journey. I came to All In One Fitness to control perimenopausal weight gain. I have been going twice a week for the past 6 months. Joceline’s expertise, motivation, and personalized approach have completely transformed my thoughts on what a fitness journey would look like. I've not only achieved personal fitness goals but also learned so much about proper form, nutrition, and overall wellness. Joceline’s dedication and encouragement have made every session enjoyable and rewarding. Watching Joceline get excited over my progress and transformation keeps me motivated to continue this journey with her. She is your personal cheerleader and is there for you 200%. I highly recommend working with Joceline to anyone looking to take their fitness journey to the next level. ~ Sylvia A

Joceline is an excellent trainer with a great attitude. She is conscientious and knowledgeable, but more importantly she approaches every session with fresh dedication. She makes sure to be in communication at all times so that she can modify the exercises to fit my goals and needs. ~Chris  


I have been working with Joceline for just over 6 months now, and what a treat! She does a great job at motivating and cheering on her clients to help get the best out of them. She constantly has new things for me to try, and no 2 workouts are ever the same! I appreciate her fitness and nutrition knowledge, and she has provided helpful suggestions on meal-prepping and getting in more veggies!’’ ~Elizabeth M.


I just have to give a huge shoutout to my amazing personal trainer, Joceline. Thanks to her guidance and motivation, I've gotten so much stronger and my old joint pain has decreased significantly. I can't recommend her enough to anyone looking to improve their fitness and overall well-being, and all in a supportive and non-intimidating space. Thanks Joceline! -Kathleen


I've been training with Joceline close to two years and highly recommend her. At 72 years old I was looking to improve my health and mobility after being diagnosed with diabetes. With her training and expertise my health has improved immensely. Joceline is fun to work out with and pays attention to your physical needs. She changes up the exercises every session and is always very encouraging and a good listener. She might be small but she's a mighty trainer.
