What the Team is Known For

DLA Piper is a full-service firm with a strong private client tax controversy practice. The firm regularly advises on complex tax disputes at the national and international levels.

Strengths

The lawyers were extremely knowledgeable in both the substantive law and the procedures applicable to prosecuting our claim.

I've only had very good experiences with DLA Piper. It's a worldwide firm with multiple specialties. I have been very satisfied with the attention that they gave me as well as their technical and practical expertise.

I think DLA Piper is a fantastic firm. In tax, they are really good: they're very well-rounded and have grown a lot and have succession in place. They have a deep bench and lots of strong associates.

Notable practitioners
Diana Erbsen

Diana Erbsen is a highly experienced tax controversy practitioner working out of DLA Piper's New York office. She is well regarded for her practice in this area and regularly advises private clients on criminal and civil tax disputes.

I work with Diana Erbsen very closely and I have only very positive things to say. She has extensive industry experience and she knows all the relevant parties in federal tax. She is an industry leader.

Diana Erbsen is one of the best attorneys. She's very strategic and is one of the best advocates for her clients. Diana is extremely responsive and an expert when it comes to the IRS. She's able to guide her clients and colleagues through difficult situations.

She is a true life-saver. I am responsible for a multimillion-dollar legal spend and would give it all to Diana if I could.

Diana Erbsen displayed impressive expertise in the subject matter of our claim. She was a pleasure to work with. We felt very well represented by her.


Ellis L Reemer

Ellis Reemer leads DLA Piper's tax controversy practice and draws from his experience in the IRS Office of Chief Counsel to advise clients.

Ellis Reemer is very goal-oriented. He is very driven to get the best possible outcome for his clients, and he is no-nonsense about it.

Ellis Reemer is someone who has been around a long time in the tax community, so he brings a certain level of experience to my engagement that is invaluable.

Ellis is a pleasure to work with. He is always smiling and positive, no matter the topic, issue or pressure. There's no other attorney we would want in our corner.
