J. Mark Heldenbrand, PC

As our client, you can be assured that Mr. Heldenbrand will oversee all aspects of your legal matter, with thoroughness and precision, clearly explaining the work to be done on your behalf, and advising on the best direction to take in efficiently resolving your legal issues.

Our firm’s litigation philosophy is to prepare early and thoroughly, so that clients can more readily assess their legal position. We do this by obtaining the facts, and the applicable laws, at the very beginning of the representation. Through the years, this philosophy has encouraged and facilitated early resolution, in most instances keeping legal expenditures to a minimum. In other matters, early preparedness leads to summary disposition of cases, or places our opposing parties and their counsel at a significant disadvantage.

To learn how seasoned legal representation may assist you or your organization, please contact J. Mark Heldenbrand, PC to schedule a consultation or obtain more information. In order to best accommodate our clients, we offer weekend and evening appointments. Spanish speakers are welcome. Se habla español.
