Testimonials
“I can’t say enough about Cassandra at Somatic Engineering, LLC. I see her for strength training, stretch work, and wellness, and her understanding of the body is incredible. She explains everything in a way that makes sense, which really helps you feel confident and comfortable. Each session is tailored to you, and I always leave feeling better and more informed. It has made a real difference for me. Cassandra is a wealth of knowledge.”
“A friend recommended Cassandra to me several years ago and I’m so glad they did! I deal with chronic pain and used to struggle to find ways to exercise without triggering my body. Cassandra always checks in about how I’m feeling and adjusts workouts in real time so they work for me that day. Since working with her I’ve gotten much stronger and the back pain I used to deal with regularly is gone. She’s great at explaining movements and strikes the right balance of being supportive while still pushing you to do your best. I love that she offers both in person and virtual training, which makes it easier to stay consistent. I recommend her to anyone looking for a thoughtful trainer, especially if you struggle with chronic pain!”
“Cassandra is absolutely fantastic with everything wellness! Stretching is only one of her many talents! As my personal trainer right out of COVID, Cassandra helped me become healthy in mind and body. I give her all the credit.”
