Our care model

A deliberately small clinical practice.

MindHealth Psychiatry limits its panel size to preserve continuity of care. Whenever scheduling allows, patients continue with the same clinician across follow-up visits, and the full record of your evaluation, prior trials, and treatment plan stays with the practice. The goal is to minimize repeated intake histories and mid-course plan changes as care progresses.

Initial evaluations are scheduled at extended length rather than in brief increments. The first appointment covers psychiatric and medical history, prior medication trials and their outcomes, and screening for conditions that frequently present alongside the primary concern. A thorough initial assessment reduces subsequent trial-and-error prescribing.

Administrative functions are managed in-house: scheduling, insurance verification, prior authorizations, records requests, and billing. Benefits are confirmed prior to the first appointment, and questions involving a pharmacy or insurer are handled by a single designated contact familiar with the patient record.

Credentials & scope

What a PMHNP is and does.

Licensure
Lavena holds active Psychiatric Mental Health Nurse Practitioner licenses in both Oregon and Washington, and is board certified through the ANCC (PMHNP-BC).
Prescribing
PMHNPs evaluate, diagnose, and prescribe psychiatric medication independently in both states — including controlled medications such as stimulants, with the same DEA registration requirements that apply to physicians. More on what a PMHNP is →
Specialized training
Cognitive behavioral therapy for adult ADHD through the Beck Institute, alongside an integrative approach to medication management.
Scope
Adults 18 and older. We treat ADHD, depression, anxiety, and PTSD. We do not treat children or adolescents, and we do not provide talk therapy in-house — though we coordinate closely with therapists and will help you find one.
