Excellent Attorney
Allen is a great attorney and a wonderful person. He stuck with my law suit when other attorneys would have given up. He has many years of experience and never gets intimidated. He digs in and researches until he finds a brilliant, winning solution - even when he takes on the giants who are supposed 'experts' in their fields. I will continue to work with Allen when I need legal help in the future and can't say enough good things about him. I highly recommend him.

Great experience
We’ve worked with many lawyers but Attorney Landerman is, by far, the best attorney that we’ve encountered. He possesses a wealth of knowledge in many diverse disciplines including software, business, and education. We plan on working with him for many years to come.

Highly Recommend
I hired Allen Landerman to help out with a rental security deposit issue. I was worried that we would not be able to collect from the landlord but Allen was very knowledgeable and made it happen. I’d definitely hire Allen again.

This is a long-overdue review for Allen.
This is a long-overdue review for Allen. Allen has helped me with multiple business reviews from business acquisition, drafting necessary documents, and standing next to me from start to finish. I recommend Allen to anyone who is looking for a business lawyer and overall legal help. Allen is a guy who will pick up the phone, and you can talk about any legal challenges. He has decades of experience, and it shows in his passion. He knew how to navigate every path and pitfall and was always seeing things before they happened! He doesn't merely help his clients as clients but as a family. There are no words to describe how grateful I am for what he accomplished for my company. As we grow, our portfolio Allen is the first phone we make to review our initial plan. Thank you.

Partially Probated Suspension means an attorney lost his or her license to practice law for a period of time.
