Brent Patterson, D.D.S.

I am the founding owner of Texas City Family Dentistry and League City Family Dentistry. I was born and raised in Texas City and graduated from TCHS in 1989. My road to a dental education passed through a little town called College Station where I attended Texas A&M University GIG’EM. After a well-earned Biomedical Science Degree, I attended one of the top-rated dental schools in the country, UT Health Science Center Dental School in San Antonio. In 1997 I received my Doctor of Dental Surgery degree and headed back to the Bay Area.

The Texas City office opened for patients in August of 1999 and moved to it’s new much larger location in 2016. We opened our second office in League City in 2005 and moved to our own building in 2013 whosed design was inspired by my family’s travels in Italy. Lately I’ve devoted most of my time learning about Sleep Dentistry. It’s a new and exciting world where dental meets medical and our office is one of the few around who can help those patients unable or unwilling to use a CPAP machine for their sleep apnea.

Outside of dentistry, I enjoy working with the community via service organizations – TC/LM Jaycees, Texas City Foundation for the Future and the 9th District Dental Society and spending time with my family. My wife Michele is also a TC native who graduated from TCHS (’88) and Texas A&M (’92). She is a CPA and is the Manager of our Family Dentistry organization. Our oldest Samantha Is currently at Texs A&M Galveston working on her Bachelors in Marine Biology with a Minor in Diving and our boy Tucker is also at TAMUG working on his General Studies.

You will not find me on the golf course – I have enough frustrations during the week!!! I spend my ever-shrinking free time with the kids and or tinkering with new technology integration into dentistry.

Mark Martinsen, DDS

I was raised in Friendswood were I graduated from Friendswood High School in 1997. I then attended Texas A&M University where I received my Bachelors of Science degree in Biomedical Science with honors. After graduation, I studied at Texas A&M University-Baylor College of Dentistry where I received my degree of Doctor of Dental Surgery.

Since then, I have completed hundreds of hours of postdoctoral continuing education. I am dedicated to the newest advancements in cosmetic and general dentistry and keep up-to-date with the latest technologies and state of the art dental procedures.

After practicing for a number of years in Dallas, my wife, Stacey and I decided to move back to the Houston area to be closer to family. When I am not practicing my passion of dentistry, I spend most of my time with my two daughters, my son and my wife. In my free time I enjoy all sports and anything involving the water.

David Colombo, D.D.S.

I have practiced dentistry for 30 years in Galveston, first as an associate, then opening my Seawall practice in 1996. I was raised in Galveston, class of 1980. I completed my undergraduate education from Stephen F. Austin State University in 1984, then attended Dental School at The University of Texas Health Science Center Dental Branch at Houston. After receiving my Doctor of Dental Surgery degree in 1988, I went home to Galveston to begin my career. I married my wife Kim in 1989 and we have three great kids, Danielle, Kyle and Jacob. All of them are active in sports and school activities. They are a full time job in and of themselves! My spare time is consumed by my two passions: my kids’ activities and my surfing. I’m in the water every chance I get. It’s a great release and a good excuse to go to cool tropical locations for vacation! I came to League City Family Dentistry in October 2008 after hurricane Ike made landfall and I’ve been here part-time ever since.
