Lori,
You're amazing...you can pivot in a moment's flash... if you could bottle that productivity and sell it to seniors you could buy California, despite the fact that you already help many people and make their lives better!! Stay YOU!!!

Lori and her team provide personal training for my elderly mother who has Alzheimer's and dementia, as part of her overall care. They customized a program addressing her needs, including balance and mobility. She really likes her two trainers and looks forward to her sessions. I highly recommend Lori Michiel Fitness!

Lori did a great job of matching my mom with an excellent personal trainer. It's been close to one year and the trainer has done incredible work with my mother and has shown such care and patience while helping my mom maintain and improve her mobility and strength...Seeing my mom become stronger and more confident as an elder has been wonderful. I am so grateful for the personalized attention and genuine heart of this fitness company. I highly recommend Lori Mitchell Fitness to anyone over sixty-five looking for personal trainers who are empathetic, professional, and truly dedicated to the well-being of their clients.

Sam Strain – Trainer
Customer care is of the utmost concern to her. She is very knowledgeable about personal training and the workings of the functional human body from a bio-mechanical point of view. She is compassionate about all her clients as they all get her personal touch.
I would feel most comfortable recommending her to anyone that is in need of her services.
Respectfully,
Samuel Strain II NASM/CES
