Our Team


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.  Prior to opening my own office, I spent my first few years practicing as an associate with Dr. Frank Little in Clear Lake and a good friend of mine, Dr. Frank Bonno in Santa Fe.  I also worked for a time at the Galveston County Health District Dental Clinic in Galveston.
The Texas City office opened for patients in August of 1999 and the League City office made its debut as one of the most modern dental offices in the state in November of 2005.
Outside of dentistry, I enjoy working with the community via service organizations - TC/LM Jaycees, etc. 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 was born while I was a senior in dental school and our boy Tucker was born 2 years later.  They keep us very busy and very happy.
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 and wife.  In my free time I enjoy all sports and anything involving the water.

David Colombo, D.D.S. 

I have practiced dentistry for 20 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. Fortunately, my office and home received little damage. I approached Dr Patterson to allow me to practice part-time in his League City location. He and Michele were kind enough to oblige, and I have found a great site for my second office. I plan to stay on and building a nice second practice in the northern county.

I have been working with Dr. Patterson since 2003.
I am a mother of three wonderful boys.  My hobbies include working out, spending time with my family, boat rides, and weekend rides on a Harley with friends!
