A Note From the Founder

Hi! I’m Cindra Kamphoff. I know what it is like to spend too many years playing small and getting in my own way. When I was in high school, I ran the fastest mile in the state of Iowa. I dreamt of becoming an Olympian! Despite the success I was having, I secretly struggled with self-doubt and often wrestled with the thought of quitting the sport I loved so much.

As an entrepreneur, I’ve also been overwhelmed with the belief that my dream was too big for me… I was afraid to share my goals with people, and I often thought there must be something “wrong” with me for dreaming this big. Am I just being delusional? Who the heck am I?

A long time ago, I had a coach who helped me get out of my own way, and fully believe in myself. The truth is I got lucky. Coaches are a dime a dozen in this country… but just like everything else in life, there are only a handful who deserve the title.

I created Mentally Strong to do for others what my coach did for me. This is my passion and calling. I am living my dream, and it means the world to me when I know I’ve had a small part in helping someone else live theirs.

My husband is an elementary school principal and was a teacher. I’ve seen the impact that COVID and the changing nature of our kids have had on our educators.

Over the years, I have trained, mentored, and hand selected coaches to stand beside me and help in my mission. Together, we make up the Mentally Strong family. My coaches are equally as passionate about supporting you, and skilled in training you to be your best. We are all here to help you. You’re reading this for a reason, it’s no accident. This might be the perfect time to see what you are really made of!
