Our Firm - Federal Lawyer

Our Firm

When Oberheiden P.C. was created in 2010 by founding partner Dr. Nick Oberheiden, the goal had been to launch a law firm where senior healthcare defense lawyers could legally represent individuals and healthcare providers accused of fraud in federal district courts across the United States.

In the years since then, our firm has expanded into over 40 states and have added a legion of experienced healthcare fraud defense attorneys to our staff of exceptional trial lawyers.

From our headquarters in Dallas, Texas, and our staffed office in Houston, Oberheiden P.C. directs a network of other offices in nearly every major city in the country. Regardless of where you are, you can call a local Oberheiden P.C. law office and speak with a healthcare fraud defense lawyer who has handled hundreds or even thousands of defense cases.

Oberheiden P.C. is a National Healthcare Fraud Defense Firm

Lots of law firms aim to provide exceptional legal representation to defendants that are facing allegations of wrongdoing. Oberheiden P.C. wanted to provide it in federal district courts across the country, from Georgia to Texas to Arizona to New York.

The lawyers at all of our offices have extensive experience in representing defendants facing a wide variety of allegations related to healthcare fraud, including:

These allegations can arise in a wide variety of ways. However, they most commonly come from:

Getting skilled legal help on your side for these preliminary inspections and complaints can prevent them from collecting evidence of healthcare fraud and escalating into a formal civil or criminal charge by federal law enforcement agencies.

We Pride Ourselves on Providing Personalized Attention

A common client complaint is that large law firms like ours fail to provide personalized attention that you deserve. We take that complaint seriously and do everything that we can to ensure that our clients never feel that way.

To that end, not only do we make ourselves available to our clients at all hours of the day and every day of the week, we also have gone to great lengths to fill our law office with fluent speakers in as many different languages as possible. In addition to English, you can speak to our lawyers in 11 languages:

  1. Chinese
  2. Spanish
  3. Korean
  4. French
  5. Arabic
  6. German
  7. Hausa
  8. Portuguese
  9. Urdu
  10. Tagalog
  11. Vietnamese

This is just one of the ways that we strive to make our clients feel at home and in good hands.

We Represent Healthcare Providers of All Sizes

Our healthcare fraud defense lawyers have lots of experience handling a wide variety of cases that span all across the field of healthcare law. In addition to a broad range of practice within the field, though, we have also provided effective legal representation to a wide variety of clients as well, including:

  • Doctors
  • Nurses
  • Surgeons
  • Anesthesiologists
  • Pharmacists
  • Medical billing staff and coders

As you can see, our experienced lawyers have defended both individuals and corporations, large and small, from serious allegations of healthcare fraud. This has given them a depth of insight that many other law firms lack when it comes to appreciating the severity and the variety of concerns that our clients can bring into their case.

You Only Deal With Senior Healthcare Fraud Defense Lawyers

In order to best represent our clients, Oberheiden P.C. long ago made an unconventional decision: We would only employ senior attorneys on our staff.

No paralegals. No junior associates. Not even any legal secretaries.

While we have a roster of experienced and extremely skilled investigators to help our lawyers gather the facts in your case, even they have decades of experience doing so in a law enforcement capacity, often working for the very same agencies that are likely investigating your case.

We made this decision not just to increase the personalized attention and the legal wisdom that you get over the course of our representation, but also to decrease the odds that your needs and concerns are overlooked by internal communication breakdowns within our firm. When you call Oberheiden P.C. at (888) 680-1745 or contact us online, you speak directly with a senior lawyer that will be involved in your case – not a staff member who has to relay your message up several rungs of the ladder before it is heard.
