Dr. Kevin O’Brien

My career focus has always been on health care, and I made a commitment at a young age to help others. I initially struggled with what branch of healthcare was a fit for me.

I began my undergraduate degree as pre-med. After several long discussions with a medical doctor and close family friend I began to explore other avenues. My uncle, the dentist, recommended his career. After a summer research project at the University of Texas Dental School, I realized that dentistry was not for me.

I had never visited a chiropractic office until 1998. After visiting a great clinic in Austin, Texas, I really understood what chiropractors had to offer. I was inspired by how well one gets to know their patients and what a drastic change chiropractic care can make in a patient’s life. I knew within minutes this was how I was going to help people.

A Chiropractic Education

I began my higher education with a degree in Biology from the University of Texas in Austin. Upon graduation, my desire to help others translated into receiving my Doctor of Chiropractic with Magna Cum Laude honors from Texas Chiropractic College. I practiced with another doctor in the area and opened my own practice in 2003.

My Philosophy

I have a very simple, flexible approach to my practice: We are here to help you feel better. We have an “if it is broke, fix it” approach; after that, let us maintain a healthy lifestyle on your time. We explain everything in advance to help you make positive decisions that will get you back to living a healthy and active lifestyle (and keep you there).

On a Personal Note…


I met my wife, Meredith, at The University of Texas in Austin, and we married in 1998. We relocated to Houston after graduation and moved to the Kingwood/Atascocita area in 1999 while I finished school. We have two beautiful daughters, Madeline and Kathryn. Much of my free time is spent with my family. My family and I get adjusted regularly and seem to avoid catching every cold or flu that goes around.

Working in the chiropractic field has also made me realize the importance of exercise and weight training. I take classes at Solis Martial Arts, focusing on Jiu Jitsu, and exercise regularly. Exercise and proper nutrition help me balance the physical and mental aspects of my life.


Ellen Belk, DC

Board Certified Chiropractor

Dr. Belk grew up in a small town in Mississippi where she was involved in gymnastics, cheerleading, dance, baton twirling and track throughout high school.

She grew up always wanting to pursue a medical degree but was never quite sure which avenue she wanted to go. While in high school, she discovered a new interest in physics from a mechanical standpoint. She initially pursued engineering due to her interest in physics but soon found out in her freshman year of college, engineering was not her calling.

She decided the best way to combine physics/mechanics and medical would be to pursue Chiropractic and went on to Mississippi State University to receive her bachelor’s degree in Biological Sciences with a Pre-Medical focus in 2015.

She then moved to Pasadena, Texas to begin Chiropractic School. She received her Doctorate from Texas Chiropractic College in December of 2018 and soon thereafter began her career at n8 massage with Dr. O’Brien and staff in January of 2019.

Her mission in chiropractic is not just to treat patients and their ailments, but to educate them on how to help themselves at home to prevent further injury and enjoy their lives with less pain and more movement. Her passion is a focus in prenatal and postpartum chiropractic and rehab as well as pediatrics.

When she is not in the office, she spends a lot of time with her daughter and family in the area as well as at her church, learning piano, and likes to play ultimate frisbee and go out Texas two-stepping with friends.
