HNI knows that you too, are a client and deserve special care as well. We strive to make the interaction between your office and ours as efficient and productive as possible. Please consider using the tools below to assist you in your referral needs.

Helen Muniz is our business manager in charge of process, procedures, and policy. Memorial Hermann performs all billing functions on behalf of HNI.
