    He was kind, knowledgeable, attentive, and honest. I particularly liked how he broke down the process as required for insurance. I've had many problems with health insurance lately, and it was reassuring to have him know the processes and what is covered and not covered.

In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.
