Client Testimonials


Ms. Marvel has assisted me regarding child support issues for the last 3 years. She is very knowledgeable in child support issues in Texas and also across state lines such as California. She came highly recommended to me by a fellow attorney, the highest compliment she can receive in my opinion. She is professional, responsive and gets the job done. Her staff is very helpful, returns calls and Karen and her staff are responsive to issues that arise. I highly recommend Karen Marvel to anyone seeking a family law attorney in Texas.


Karen Marvel is an excellent family lawyer, who presented at a legal conference I attended. I learned valuable information and tools from her that I now use to help my own clients. After the conference, I’ve called on her a few times when I needed her expertise in child support matters, and she was always willing to help. She is extremely well-respected in our legal community, and I highly recommend her services.


I hired Megan through Mr. Wong. She returned my call immediately. She was super personable and emailed me all the information in a quick fashion. On the day of the Divorce she walked me through every step and gave me advice on another issue I was having. Even pointed me in the direction to pursue a related issue. I will be recommending her to anyone going through a divorce. Even after all that I received a follow up e-mail asking how I was doing and if the information panned through.
