Med­i­cine requires a strong rela­tion­ship between provider and patient. I strive to use evi­dence based med­i­cine in con­junc­tion with lifestyle mod­i­fi­ca­tion to achieve the most favor­able outcomes.

Qual­i­ty mat­ters when it comes to sup­ple­ments. Whether you’re new or expe­ri­enced with sup­ple­ments, trust­ed, qual­i­ty options can sup­port your immu­ni­ty, heart health, and nutri­ent intake. Duly has part­nered with Fullscript, offer­ing access to high-qual­i­ty sup­ple­ments deliv­ered direct­ly to your door. Ask your provider about Fullscript at your next vis­it and receive exclu­sive discounts.
