30-day fills

$469,276 in 2024

Years since graduation

30 years (graduated 1996)

CMS Doctors and Clinicians data list 1996 as the year this clinician finished professional school.

Medicare assignment applies to Original Medicare. It does not tell you whether the clinician is in a Medicare Advantage plan's network, accepts other insurance, or is taking new patients.

Telehealth (some services)
