Jamie came to MCG in 2004 following PR positions with the Dallas Symphony Orchestra and the Texas Department of Criminal Justice.


Clients trust Jamie to bring positive attention to their projects through the strategic use of special events, social and mainstream media. Whether it is helping to lease a new modern downtown skyscraper, helping bring an aging downtown building back on the market with a huge media splash, helping market one of Texas’ most successful planned communities or a successful groundbreaking for one of the nation’s largest motorcycle dealers, Jamie is the perfectionist who gets the job done.


Clients also turn to Jamie for her insight and expertise during a crisis.

Jamie and her husband Scott love to travel and have raised three really great kids.

Do you have any pets? A cat named Kitty Biscuit


If you could possess one super-human power, what would it be? To eat anything I want and not gain weight.


What do you like to do in your spare time? Hobbies? Read, travel, Netflix and read some more.


Favorite quote/movie line/saying? “My name is Inigo Montoya…”


What first attracted you to the PR field? The fact that there are so many different kinds of career opportunities (writing, events, media relations, crisis communications, etc.) and settings (agency, non-profit, government, for example).


What was your first job? Other than baby-sitting, working as a checker at the Winn-Dixie grocery store on Gaston and Garland Road in east Dallas.



Who is the biggest influence in your life? My father. He volunteered to serve in World War II, fought in the Battle of the Bulge and never once complained about the hardship and sacrifice that came from his service. When the war was over he came home and built a life for himself and his family.


What is your funniest story working in the media? I asked my boss at WFAA-TV if I would get a raise because of the strong ratings for the newscasts I was co-anchoring. He explained that it was a team effort so I couldn’t take the credit. I said that was fine as long as I would not be blamed if the ratings went down. His answer, “that’s not how it works” helped me decide to start my own business.


What is your most memorable news story? In San Antonio I was an investigative reporter, produced a number of documentaries and anchored the news. But was best remembered for a story where I interviewed turkeys about Thanksgiving. The farmer was able to get them to respond to my questions by whistling.


What was the best decision you have ever made? Marrying my wife, Kathy, in 1980


What was the worst decision of your life? Buying Kathy a car she didn’t like.


What is your favorite thing about working at MCG? The environment. We have a lot of autonomy at work. David trusts us to come in and get our work done, he doesn’t micromanage his employees. We know he’s always there if we need him. My coworkers aren’t so bad either and on Friday’s the day ends at 4 pm!


Favorite quote/line/saying? "When in Rome!"


What’s your go-to cocktail? Old Fashioned


What do you do on your days off? My usual off day includes working out, walking the dog, doing something productive around the house (cleaning or working on a project), then relaxing or going out either with friends, to dinner or to a movie with my husband. If I’m feeling lazy, then my off day will include laying around snuggling with the dog watching Lifetime movies.



What are three things still left on your bucket list? See the Aurora Borealis, travel to Paris, attend Oktoberfest in Munich



Favorite Quote? “Be water, my friend.” – Bruce Lee


Before working at MCG, what was the most unusual or interesting job you’ve ever had? I worked for a cleaning crew that washed private airplanes.


What’s the coolest (or most important) trend you see today? VR and wearable technology


What is your go-to comfort food? Chicken Wings


What would be the movie title for the story of your life? Learn. Grow. Adapt….. staring Ryan Reynolds as James Roth


Who was the most influential person to you as a child? My grandpa and still is today.


Crisis Communications - Public Relations - Strategic Marketing



Do you have any pets? We have a lovable and very cuddly 11 year old shih tzu, Gracie. I highly recommend this breed!


What do you like to do in your spare time? My family and I love to travel. I was once told that I had to have been a travel agent in a prior life as I love to research places to visit. There are still many places out there waiting for me! While at the beach, I enjoy snorkeling and hope to soon take my diving certification. Going the other direction, I like to strap on the skiis in the winter. Regardless of location, I enjoy reading every night before turning out the light.


What’s one thing you can’t live without? Materialistically--my cell phone. Realistically--my family.


Where do you see the future of PR heading? I was somewhat skeptical of social media when it first launched. Was it legitimate or a fad? Over the next few years, I see PR heading in a more digital direction—less print, less TV, more social media, and more online content. This will pose more of a challenge to businesses to be fast and accurate with information, and we’ll be there alongside to help!


What was your first job? I started mowing yards when I was in the second grade. I had a lawn business with my older brother that I continued through early college. I was very frugal with my lawn money, saving most of it. This savings allowed us to buy our first home several years later.
