What Counseling covers

A psychologist who specializes in general practice and health service. It focuses on how people function both personally and in their relationships at all ages. Counseling psychology addresses the emotional, social, work, school and physical health concerns people may have at different stages in their lives, focusing on typical life stresses and more severe issues with which people may struggle as individuals and as a part of families, groups and organizations. Counseling psychologists help people with physical, emotional and mental health issues improve their sense of well-being, alleviate feelings of distress and resolve crises. They also provide assessment, diagnosis, and treatment of more severe psychological symptoms. NUCC Health Care Provider Taxonomy, code 103TC1900X

Full NPPES record

An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check

1235120650 passes the NPI check digit test The final digit 0 matches the value computed from the first nine digits, so this is a well-formed NPI.
How the check works, step by step

Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.

Digit 8 0 8 4 0 1 2 3 5 1 2 0 6 5
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 2 6 5 2 2 0 6 1

Sum = 50 · next multiple of 10 = 50 · check digit = 0 · actual last digit = 0

A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
