Years on the Department:  20

Profession:  Director of Engineering for Elbit Systems of America

I moved to Double Oak in April of 2000 and soon after in July joined the ranks of the amazing organization that is the Double Oak Volunteer Fire Department.  I have wife and 2 boys, one in high school and the other a sophomore at Oklahoma State University studying Chemical Engineering.  If I’m not on a fire call or teaching the youth at church you will find me either playing my guitar or fixing things around the house.

Years in Department: 15

Profession: Physical Therapist

I moved to Double Oak in 2002 and joined the department in July 2004. Raised in a military family, Double Oak quickly became home and is the place I have lived the longest. When not at work or at the FD, I can be found at home doing projects, hanging by the pool, or enjoying an evening around the fire pit.

Profession: Regional Sales Manager

I moved to Double Oak in 1997, that’s when I joined the department. I am married, have a daughter and and awesome grandson. I also have a job with Sunoco, supplying fuel for NASCAR.  Work and the Fire Department is where I spend most of my days. When I have available time I spend as much as possible with my family and friends.

Profession: Regional Sales Manager

My wife and I moved to Flower Mound 20 years ago both being from the area. (Coppell & Argyle). We have a 17 year old daughter that attends Marcus High School. As a family we enjoy traveling out of the country, going skiing, and time out on the lake. If I am not at work or doing something that involves the FD I also enjoy hunting, scuba diving, BBQing and time with friends.

Captain Jake Dale

Years on the Department:  4
Profession: Career Firefighter

My wife and I moved from Louisiana to DFW around 10 years ago and after a short stint in Frisco, we landed in Flower Mound.  I stumbled across the DOVFD website one day, and as luck would have it, we lived close enough to the Station that I was eligible for membership.  I’m a proud father of a determined 8-year old boy and a full of personality 6-year old girl.  I enjoy activities that involve working with my hands, spending time outside, and eating my wife’s Cajun cooking


Captain Mike Unger

Years on the Department:  2
Profession: Insurance Adjuster

We moved to the Double Oak area about 2 years ago having been out of the country for about 5 years. Volunteering on a fire department was very important to me from my past years of experience, I tried to locate a volunteer department in the area and found DOVFD. We searched for a home close to the Fire Station, which allowed me to be able to be a regular part of the department. I love to travel, hike, ski, mountain bike and sail, and do anything outside really. Very happy to be a part of a great department with excellent membership.
