How to Open a Nurse-Owned Practice in Illinois

You've done the math in your head more than once. A few injectable appointments on your day off, on your own schedule, in your own space, and suddenly the shifts you pick up out of obligation start to look optional. Illinois is the biggest market in the Midwest, and the Chicago suburbs are full of patients who already drive 40 minutes to see the injector they trust. Downstate, a nurse-run practice in Peoria or Champaign often has no real competition at all. (Already run your own practice? Skip ahead, there's a section below built specifically for you.)

The thing that stops most nurses in Illinois was never the clinical work. You already do harder things on a Tuesday than a first tox or IV appointment will ever ask of you. What stops people is everything around it, the ownership rules, the medical director, the setup, all sitting there as one giant undefined to-do. So let's take it in order, starting with the question every Illinois nurse asks first.

Can a nurse own an aesthetics, wellness, or functional health practice in Illinois?

Not outright, unless you're an APRN with full practice authority. In a memo updated October 30, 2025, the Illinois Department of Financial and Professional Regulation and the Department of Public Health said a medical spa must be owned and operated by physicians, or for some services by APRNs, and that "a person who is not a physician or an APRN cannot be a shareholder or member, officer, director, or manager" (IDFPR/IDPH Medical Spa Memo, citing 225 ILCS 60/54.2 and 225 ILCS 65/65-43). An RN can still inject: a physician may delegate cosmetic procedures affecting the living layers of skin to "a licensed practical nurse, a registered professional nurse, or other licensed person" inside a physician-patient relationship (225 ILCS 60/54.2).

The Illinois rule that catches almost everybody

The license on the door decides who can sit on the cap table. Physicians organize under the Medical Corporation Act, the Professional Service Corporation Act, or the PLLC Act. APRNs get the last two only, and an APRN entity "must likewise only have APRNs as shareholders or members, officers, directors, or managers" (IDFPR/IDPH memo). Illinois health law firms describe a separate management company beside a professionally owned clinical entity, which, yes, is as much paperwork as it sounds. No specific Five Square structure for Illinois exists yet.

Can an NP be the medical director in Illinois?

Yes, once the NP holds full practice authority under 225 ILCS 65/65-43. The bar is real: 250 hours of continuing education or training in the certification area plus at least 4,000 hours of clinical experience after national certification, earned under a written collaborative agreement (68 Ill. Adm. Code 1300.465). After that the APRN practices without a collaborative agreement, prescribes legend drugs and Schedule II through V, and may delegate nursing interventions to an LPN or RN. With a physician director, the clinical entity has to be physician-owned and the nurse's work runs on delegation under 54.2.

The initial patient evaluation in Illinois

Illinois never says good faith exam, so call it the initial patient evaluation, which some states call a good faith exam. The memo frames every delegated cosmetic task as happening "within the context of a physician-patient relationship," and for non-ablative laser it adds that since January 1, 2025 an on-site physician exam isn't required when the facility follows a delegation protocol or an APRN performs the exam. Nothing says whether that evaluation can happen by telehealth for injectables, so ask counsel before you build a workflow around video visits.

One that surprises people: the same memo names Botox, collagen injections, microblading, and microneedling as off limits for estheticians and cosmetologists (225 ILCS 410/3-1 and 3A-1).

How Five Square actually gets you started

The whole thing lives in one place: the free Five Square Nurses app. Your medical oversight, the step-by-step training, your pharmacy and vendor accounts, and the entire community of nurse business owners are all in there. You can open it between patients, on a lunch break, or on the couch at 9pm, and pick up right where you left off.

When you join, you're not handed a login and wished good luck. There's a Getting Started path that puts the order of operations right in front of you, so the mountain becomes a checklist.

You pick your lane, or combine them. Five Square supports three:

• Aesthetics. Tox and dermal filler, the core of a nurse-injector practice, with room to add more as you train.
• Wellness. IV therapy and vitamin injections. Low startup, very mobile-friendly, and a natural add-on to aesthetics.
• Functional Health. Peptides, lab work, and whole-person care for nurses who want longer-term, relationship-based patients.

You bring the nursing license and the nerve. We bring the medical director, the compliant Illinois setup, the training, member pricing on products, marketing help, and weekly live calls with experts and other nurse owners, so you're never stuck guessing alone.

And every Five Square member, brand new or already established, gets instant on-demand Good Faith Exams for $19.99 each, a price we subsidize because we believe in nurse success. A walk-in can be cleared in about a minute, seven days a week, and the exam paperwork lands right in the patient's chart, which is exactly what a state board wants to see.

You start before you feel ready, and that's the point

Most programs make you wait. Watch every module, sit through every call, and someday you finally see a patient. By then half the people who started have lost momentum. Five Square runs the other way: you start your practice while you're still finishing the training, because the training sticks when there's a real patient on next week's calendar.

Kayla, an ER nurse in North Carolina, had never injected anyone when she joined. She watched the videos, took notes, and set a goal of 30 people in 30 days. Here's the advice she'd give a nurse who's scared to start:

"Believe in yourself, even when you don't know how to do something. Figure it out. The clinical knowledge from your nursing career is more than enough to get started, and there's a community of people around you who want to help. Do it scared."
- Kayla, ER nurse

She launched April 4. Her first month: 46 appointments, 28 good-faith exams, and $10,320 in revenue, run out of a single room inside a salon she'd been a client at for years. That's one real month from one real nurse, not a typical result and not a promise, and your market and hours are your own. The point is she was exactly where you are, never-done-this-before, and she started anyway.

Does it actually work once you launch?

Getting launched is step one. What you really want to know is whether it works after that. Here's the honest picture, numbers included, because income claims in this industry deserve a skeptical read.

Results vary, and they depend on things no membership controls: your market, your hours, how long you've been at it, how consistently you market. As practices mature, some established members report months in the $10,000 to $20,000 range. Individual results vary widely. Some land higher, some lower, and nobody here will promise you a number.

What's more useful is the math underneath, which is public. Neurotoxin appointments bring in $200 to $600. A syringe of filler runs $500 to $800. IV sessions run $150 to $350. Functional health consults run $150 to $300, often with patients coming back monthly. At those prices, two to four appointments a month would cover the $899 membership before product costs, and everything past that is the business growing. Want to see it with your own pricing? Run your numbers in the Five Square membership earnings calculator.

The nurses say it better than a revenue range does:

"As a nurse, taking risks is not in our vocabulary. Five Square made me excited about starting my own business. Timely responses, professional, highly knowledgeable, and a team that wants to see me succeed. I say my risk was absolutely worth it."
- Patricia G., 5-star Google review

"As a single mom, the thought of risking my stable nursing income terrified me. Starting my aesthetics business part-time gave me confidence and security."
- Kiley D., BSN, RN-C

Inside the community, the wins show up in real time. A nurse a few weeks into her launch posted she was already up to eight bookings, nearly all of it from one post in a local mom's Facebook group. Another saw a husband and wife for their good-faith exams in under ten minutes using the same-day exam tool when her director wasn't free. Scroll the forum any week and it's full of small wins like these.

The Google rating sits at 4.8 stars, and the reviews keep naming the same things: the setup help, the medical director, the training, and a team that answers when you're stuck.

Already run a practice in Illinois? There's a membership for that too

Not every nurse reading this is starting from scratch. Plenty of you already run your own practice and already pay for a medical director somewhere. If that's you, a lot of what's above is stuff you sorted out a while ago, and Five Square has a leaner membership built for exactly your spot. Illinois is on the Five Square expansion roadmap, and in most new states the Established Nurse Membership opens first, so if you already run a practice, you're likely first in line.

It's called the Established Nurse Membership. It's $799 a month, month to month, no annual lock. You get a medical director who's actually engaged, a compliant structure in Illinois, vendor and product pricing, the Five Square Nurse Community, and those instant on-demand Good Faith Exams at $19.99 each, a price we subsidize for our members because we believe in nurse success. There's no new-injector training folded in, because you don't need it and shouldn't pay for it. If you ever want the full education stack later, you can add it.

Here's the honest pitch. Most established practices are either paying $1,500 to $5,000 a month for a director who's genuinely involved, or a few hundred for one who signs protocols and disappears, which is its own risk when a board comes asking. For most nurses, $799 all in beats both, on price and on what you actually get. Tell us what you're paying now and we'll show you the side by side. No pitch, just the math.

What it costs, and the catch nurses look for

For a nurse starting out, membership is a flat $899 a month for one tier, $1,199 for two, $1,499 for all three, on a 12-month term. Startup beyond that is lighter than people expect: a starter tox order, insurance that runs well under most nurses' guesses, and the products you actually use. No revenue share, ever. (Already have a practice? The Established Nurse Membership above is $799 a month, month to month.)

That's usually the moment the skeptical part of your brain asks where the catch is. Fair. So, plainly: you own your practice and your patients through your own LLC. Five Square does not take a cut of what you make, and if a discovery call turns up that the honest answer for you is 'not yet' or 'start smaller,' the team will tell you that too.

Illinois-specific costs to budget for

Articles of Organization for an Illinois LLC run $150 with the Secretary of State, and the annual report is $75 a year. Keep in mind the clinical entity in Illinois has to be a professional entity (a PLLC or professional service corporation for an APRN owner), and the IDFPR memo says those register with IDFPR on top of the Secretary of State filing, so budget for that registration and for a lawyer who's done it before. If you sell skincare or retail product, the state Retailers' Occupation Tax is 6.25% on general merchandise before any local add-on, which in Chicago pushes the combined rate well past 10%.

So, where do you actually start in Illinois?

You book the call. That's genuinely it. Not a six-month research project, a 15-minute conversation about your license, your goals, and what launching (or leveling up) in Illinois would look like for you. Whether you're brand new or already running a practice, the whole reason Five Square exists is so you're not doing the hard parts alone.

Common questions about starting a practice in Illinois

Can an RN and a physician co-own a med spa LLC in Illinois?

No. The IDFPR and IDPH memo (updated October 30, 2025) says a medical spa must be owned and operated by physicians, or for some services by full practice authority APRNs, and that anyone who isn't a physician or APRN can't be a member, shareholder, officer, director, or manager. A physician-owned entity can only have physicians in those roles, and an APRN-owned entity can only have APRNs. An RN's path in Illinois is working under delegation, or a separate management company that never owns the clinical side.

Do I need full practice authority to own a practice as an NP in Illinois?

Yes. The memo ties APRN ownership to full practice authority under 225 ILCS 65/65-43. Getting there takes 250 hours of continuing education or training in your certification area and at least 4,000 hours of clinical experience after national certification, all under a written collaborative agreement, then an attestation to the board (68 Ill. Adm. Code 1300.465). Until then you're practicing under a collaborative agreement and the clinical entity needs a physician owner.

Can an LPN inject Botox in Illinois?

The delegation statute names LPNs directly: a physician may delegate patient care tasks to "a licensed practical nurse, a registered professional nurse, or other licensed person" practicing within the scope of that person's own licensing Act (225 ILCS 60/54.2(a)). The IDFPR memo adds that LPNs work under physician delegation and RN supervision. So an LPN can be in the treatment room, with a physician's delegation and an RN over the nursing side, and never as the owner.

Can a registered nurse own a med spa in Illinois? Not outright, unless you're an APRN with full practice authority.

Do I need a medical director for aesthetics in Illinois? Yes. Illinois requires oversight for medical aesthetic services, and every Five Square practice includes a medical director as part of the membership.

Can a nurse do Botox in Illinois? Yes, within a compliant structure and with the physician oversight Illinois requires. The clinical work is rarely the barrier; the structure around it is.

I already run a practice in Illinois. Can Five Square still help? Yes. The Established Nurse Membership is built for nurses who already have a practice: $799 a month, month to month, with a medical director, a compliant structure, vendor pricing, and $19.99 on-demand Good Faith Exams. No new-injector training you don't need, and no annual lock.

How much are Good Faith Exams? For Five Square members, simple Good Faith Exams are $19.99 each, on demand, seven days a week, a price we subsidize because we believe in nurse success. One exam can clear a patient for several treatments at once, and the documentation attaches right to the patient's chart.

Is Five Square available in Illinois yet? Illinois is on the Five Square expansion roadmap, and in most new states the Established Nurse Membership opens first. The fastest way to get the timeline and hold your spot is a discovery call.

How much does it cost to start? For a new nurse, membership is $899 a month for one tier, and startup beyond that (a tox order, insurance, products) is lighter than most nurses expect. If you already run a practice, the Established Nurse Membership is $799 a month, month to month. No revenue share either way.
