Washington — NP Medspa Setup Guide
The full legal, structural, and market path for an NP-owned aesthetic practice in Washington — in plain English. Built from Washington board guidance, AANP scope data, and the playbook Faisal Darwiche, NP has used to open three practices over 27 years.
Washington is a Full Practice Authority state. That means after your transition period (if any), you can own and operate an aesthetic practice solo — no career-long collaborating physician, no MSO/PC workaround required for the prescriptive piece. This is the easiest legal structure in the country for an NP-owned medspa.
Washington practice authority: Full Practice Authority.
Can you own a practice solo? Yes. Washington ARNPs hold full practice authority as licensed independent practitioners. Washington recognizes a corporate practice of medicine doctrine, but because ARNPs are licensed healthcare professionals, an ARNP-owned PLLC or PC may own and operate an aesthetic practice within ARNP scope — no physician co-owner is required.
Collaborative agreement / physician relationship: None required. Full practice authority from initial licensure, with no transition period and no collaborative agreement.
Good-faith exam rules: A good-faith exam by a licensed prescriber (NP/MD/DO) is required before initial aesthetic medication administration. Telehealth GFE is permitted in most states subject to state-specific rules.
RN injection scope in Washington: RNs may inject aesthetic medications (botulinum toxin, dermal fillers, fat-dissolving) under a valid prescriber order and approved protocol. Only PRESCRIBING requires a licensed NP/MD/DO. Verify with your board. In Washington, when an RN performs the injection, the prescriber who issued the order must be reachable by phone within about 30 minutes; on-site presence is not required. This does not limit independent ARNP practice authority.

Not required for NP-owned aesthetic practice in Washington.
Washington does not strictly enforce CPOM against NP-owned practices.
PLLC is standard.
Entity selection is the highest-leverage decision you make at setup. The wrong structure costs you tax efficiency at scale and can create personal liability exposure. Confirm with Washington counsel before you file — this is one of the rare line items that pays for itself the first year.
Highest-demand metros in Washington: Seattle, Bellevue, Spokane, Tacoma, Redmond.
Bellevue/Eastside (Redmond, Kirkland) has the highest aesthetic spend per capita in the state — tech compensation drives discretionary spending. Seattle downtown has shifted; many practices have moved to Capitol Hill / Wallingford. Spokane is the primary Eastern WA market.
The build sequence Faisal teaches in My Practice Academy applies across all 50 states with state-specific adjustments to entity structure and medical-director requirements. Below is the order of operations — by week.
The free 17-question assessment returns a Washington-specific 90-day launch plan: entity structure, supplier sequence, build sequence, and the exact next action for your scenario. 7 minutes. No card. Built by Faisal Darwiche, NP — 27 years, three practices.
Real lean-launch cost band for a single-room NP-owned aesthetic practice in Washington ranges from roughly $25,000 (small lease, used equipment, minimum inventory) to $150,000+ (build-out, multiple rooms, full equipment slate). The bigger swing is operating runway — give yourself 90 days of fixed costs in the bank before opening.
The 90-day path above is realistic for a focused operator who is not also working a full-time clinical schedule. If you are still clinical-full-time during build, plan 4–6 months. The two longest-lead items in Washington are entity formation (1–4 weeks depending on filing volume) and building supplier accounts.
Not required for NP-owned aesthetic practice in Washington.
An RN can own the business entity, but the RN cannot prescribe and cannot perform the good-faith exam. An RN-owned medspa in Washington needs a prescriber (NP/MD/DO) on the medical side — either as a co-owner, medical director, or contracted prescriber. Same as in every other state. Memory: RNs inject in all 50 states under a valid prescriber order.
