About Us

Hameroff StaffThe firm maintains a department of staff dedicated exclusively to investigating and perfecting liens. The staff works with our hospital clients to keep them updated on the accounts as we work with the patient, the patient’s attorney, defense attorneys, and the insurance companies who are ultimately responsible for payment of the lien.

In addition to the significant financial impact we have on our clients’ bottom line, perhaps the greatest value to our clients is our constant vigilance in monitoring and anticipating the ever-changing legal landscape in the area of lien-related law. We preserve our clients’ returns while shielding them from expensive litigation, as only a law firm specializing in this area can do.

Our firm believes in a hospital’s right to be paid for the care it gives to patients. We work diligently on behalf of our clients and our partnership allows you to focus on what you do best – helping those who are injured or ill.

Call on us today to talk about how we can help and support your hospital.

David E. Hameroff has been an Arizona attorney since 1983 and has represented hospitals and other medical providers for over 25 years.

This combination made him uniquely qualified to develop this area of law. His office filed its first Hospital Lien in September 1997, and that first hospital continues to be a client today. Since 1997, David has represented multiple hospitals and his office has filed over 32,000 liens.
