About Cassandra

Greetings Athletic Adventurers,

I am so excited to bring the Athletic Adventurer programs to life for you! The mission statement behind athletic adventurer is, capable in body, adventurous in spirit, at any age. Let's work together to improve your ability to move and your confidence in trying new activities and sports.

I created athletic adventurer to help people of all ages gain confidence in their abilities and improve their athletic movement skills. When I was a kid I wasn't athletic. I was clumsy and very uncoordinated. most of my family was sedentary. There was a path to obesity and heart disease a head for me if I had followed the path I began on. Most often, when I would try sports I would just end up hit in the face with a ball. Eventually I came to the conclusion I just wasn't meant to do sports. However, I would see others having fun running around and enjoying playing sports and wished I could join with out fear of getting smacked in the face with a ball . . . again. As an adult I would stick to using machines at the gym just to try and stay healthy and in shape, but I became so board so quickly. There must be a better way or at least a more entertaining way to train! I started trying different activities and different training programs. I was so interested in figuring out how movement works I made it my career and became a personal trainer. Through a lot of hard work, study, and exploration I found the tools I needed to improve the athletic skills of myself and my clients. Through specific practice of visual skills, balance skills, strength training and rhythm training we can not only help with athletic movement abilities, but with our daily life needs for pain free comfortable movement. I am now enjoying trying new things and exploring sports and athletics I wasn't capable of when I was younger. I am doing so with confidence that I know how to move my body well and pain free. Through building your movement skills your body can become capable of things you hadn't even considered before. Understanding how your body works and knowing you have control of your movement can increase your confidence, and make trying new things more enjoyable. This brings an adventurous spirit to how you train, play, and participate in sports. No matter your age you can start practicing your skills, feeling and moving better. It would be my pleasure to be your athletic adventurer guide, as you explore your athletic skills and leave your pain and stiffness behind.

Cassandra is the absolute best. I’ve always had problems with my back, and using machines left me hurting more. She worked with me on my balance and moving certain parts of my body correctly before getting into the workout. I felt rejuvenated, more confident in my ability to exercise, lighter when I walked, and all-around much happier. After only one day, I almost had my splits back. She’s incredibly nice and the best trainer I have ever worked with.

Cassy is amazing! We hired her to help with extra conditioning for my child who is a competitive Irish dancer. She is kind yet firm in her teachings...always making sure to teach preventative care as well. We love having her as an integral part of my child’s success!

Stephanie I.

Cassandra have been very helpful with improving my overall health. She gets to know you and what you need help in improving. She has been my personal trainer for about 2 years now and has helped me make a lot of improvements in proper movement. She is a excellent trainer who is also continually learning and taking steps to learn more, so she can be more helpful for her clients.

Cassandra is awesome! She has been my personal trainer and I would not want to go anyone else. She will go over different stretches, ways to help with flexibility, different exercises and sprints to do outside of the gym. I love her and we always have a fun time during our sessions. :)

Christina P.

I love training with Cassie! In the six weeks I've been training with her I've seen more improvement than I have in years exercising on my own. She's professional, informed, thoughtful, and fun! I couldn't ask for anything more.

Sarah S.

She was super helpful with my hip problems. Had a long chat and tried some “tricks”. They worked! It was wonderful chatting overseas via skype and still having the chance to put in practice immediately and have results in a while! Super professional!

Michela F.

As a trainer, I will say all trainers need trainers. She is a great Z health trainer and has helped me with my stiff neck, low back and sciatica/stressed piriformis issues. I have seen her 3 times and every time I leave feeling so much better. I highly recommend you check her out and see how she can help you. No meds, no gimmicks, just results. Thank you Cassandra!
