Tionna Gardner, BS appears in the CMS NPPES registry as a School Psychologist provider holding BS credentials at 1750 SW SKYLINE BLVD, Portland, OR, 97221, with a listed phone of (503) 894-9630. NPI 1811885114 was issued on 06/25/2025.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many School Psychologist providers operate outside Part D entirely.

School Psychologist is a mid-sized specialty nationwide, with 13,452 enrolled providers across 52 states and an average of 1,107 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
