“Service that is large enough to serve you and small enough to care”!


We at Sierra Health Services, LLC believe that:

  1. In order to maximize your collections you need to receive the full payment due for your hard earned professional services!

  2. Often the balances owed after the primary insurance pays are left uncollected.

  3. Sierra experience applies value added services for our clients through personalized extra effort to collect what other services leave uncollected.

  4. By giving each patient’s account the necessary personal attention needed to collect the remaining balance on an account. Whether it be the patient, a surgeon’s office, the hospital or an insurance company we will make the necessary telephone call to acquire the information needed to collect our client’s fee.

  5. We have found a personal telephone call is more successful than letters or e-mails when it comes to collecting the balance of an account.

  6. It is our goal to provide our clients with all the technology benefits of the large billing companies, yet still allow them to enjoy the personal touch of a smaller company.

  7. Sierra’s clients can call and speak directly to the company partners to have their issues addressed.

  8. As owners we feel it is important to be available to our clients so we can keep abreast of the issues that are important to them.

  9. Furthermore, we believe it is important to conduct all of our business within the United States as we feel that the communication between the various components of the medical billing industry is of the utmost importance in our ability to maximize our client’s collections.

  10. Many of our competitors utilize offshore employees.

  11. Off Shore services frequently create a breakdown in clear communication which can and often does result in the loss of payments.
