About Us

Allen Law was founded with two guiding principles:

  1. Provide the highest level of personalized and attentive service to our clients.

  2. Provide our clients with the best outcome possible in any legal situation.


Allen Law is a personal injury law firm with a focus on vaccine injury claims before the U.S. Court of Federal Claims. We pride ourselves on fighting tirelessly for our client’s best interest to reach the best outcome possible in any legal situation. We focus on getting our clients healthy and compensated for their injuries. We understand that a legal action is extremely stressful and scary for our clients and we work to make that process as easy to understand and painless as possible.


Our mission is to make a personal connection with each of our clients and meet their individual needs on a case by case basis. We know that the most important factor to relieving stress during this time is communication and keeping you informed each step of the way. To ensure that this happens, we are consistently available by phone, text, and email, as well as, in person as needed.

Allen Law is based in Ellicott City, Maryland and practices vaccine injury law on a national basis. While we may not be in your local town we work to be available to you at your convenience. We are available both evenings and weekends to meet with you and can accommodate any communication method that makes you comfortable including phone, text, email, video calls and mailed documents. If you have any questions on the services we can provide please reach out to us.
