Meet Our Team


We are physicians. We are entrepreneurs. We are educators. We are patient advocates. We are not satisfied with the status quo and are always striving to do better for our communities.

We have brought together a multidisciplinary team to augment the traditional care pathways and help the millions living with diabetes and over the age 65, especially those not getting care today, to preserve their vision and quality of life. Together, we leverage our decades of clinical, retail, direct-to-consumer and operational experiences to open these new care pathways for our patients. And our innovative model allows us to do it with top quality and with a lower cost of care.
