I grew up in Mesa, AZ in a family of seven boys and one girl. After high school I served a full time, two year mission for my church and loved meeting and serving people. Upon returning I worked as a tech in a PT clinic where I met my beautiful wife. We worked our way through my undergrad at ASU in Exercise and Wellness and also had our first child in my last semester. Following ASU we went to A.T. Still University for a doctorate in physical therapy. School is where I found my passion for manual therapy. We also had our second child after my first year and the third 1 week before graduation. After graduation I was lucky enough to find One Accord PT and have been with them since 2011.
Describe the essence of what you do in your role at One Accord PT?
I believe that what we do as Physical Therapists is more than just treating pain. It is helping others to improve their quality of life through personalizing every treatment session with manual/hands-on techniques and therapeutic exercises as well as providing education on self treatments/exercise and injury prevention.
What are some of your personal interests, outside of work?
My biggest interest outside of work is spending time with my wife and children. I love wrestling, reading, playing cars, climbing on the rock wall, and running around the yard with my kids, and being able to sit and talk with my wife for hours.
What are some things you believe in? What is your favorite quote or words of wisdom?
Something I believe in is, God lives and that he loves us. I know He has a plan for us all and wants us to be happy and to serve others.
Favorite quote: A man filled with the love of God is not content with blessing his family alone, but ranges through the whole world, anxious to bless the whole human race. Joseph Smith Jr.
What do you like most about working for One Accord PT?
One thing I enjoy about working at One Accord is the focus we have to continue learning in our profession. Continuing education is an important part of our work environment to help us progress as professionals and our ability to treat those who come to see us.
What do you like most about caring for patients?
The thing I enjoy most about caring for patients is the relationship we get to have with those who come in our door. It is so much more than just a doctor-patient setting but we get to know each other and actually become friends.
Why did you choose to become a physical therapist?
I became a PT because I like helping people feel better when they are hurting. I think the human body is fascinating and I love learning about how I can help others to improve their quality of living.
What do you think patients like MOST about you?
I feel that my patients like that I have a strong desire to help each one of them feel better and improve. They can always be sure that I will be open and honest with them and that I am not afraid to say “I do not know but I will find out for you.”
What do you think patients like MOST about One Accord PT?
People love coming to One Accord because of who we are and what we offer. We have a staff that is unlike any other place I have ever worked and everyone of us has the same goal of striving to help each person who comes in. We are a happy group and we love to have a professional yet fun environment and those who come in can expect a pleasant experience.
