There comes a point in many therapists' careers when they find themselves turning away clients. The waitlist grows. Referral sources keep sending inquiries. And the realization sets in: there are only so many hours in a day, and only so many sessions one person can conduct without burning out.
This is the moment when scaling to a group practice goes from abstract idea to urgent opportunity. But turning a thriving solo practice into a successful group practice requires more than simply hiring another therapist. It demands careful planning, a shift in mindset, and systems that allow you to lead without losing the quality of care that built your reputation.
This guide walks you through every stage of the transition -- from deciding whether you are truly ready, to hiring your first associate, to building the infrastructure that makes a group practice sustainable and profitable.
Before You Scale: Are You Actually Ready?
Not every full caseload is a signal to expand. Before you commit to the significant investment of building a group practice, honestly assess whether these foundations are in place:
Financial stability. You should have at least three to six months of operating expenses saved. Hiring an associate means taking on overhead -- office space, additional insurance, potentially higher EHR costs, marketing for the new clinician -- before that associate generates revenue.
Consistent referral flow. If your waitlist has been consistently growing for at least six months, that is a strong signal. If your caseload fluctuates seasonally, scaling too quickly could leave you paying a clinician who does not have enough clients.
Administrative bandwidth. Are you already spending significant time on scheduling, billing, and practice management? If so, you need to systematize these processes before adding the complexity of a second clinician. The administrative load does not simply double -- it multiplies.
Personal readiness to lead. Owning a group practice means becoming a business owner and supervisor, not just a clinician. Your daily work will shift from primarily providing therapy to managing people, making financial decisions, and building systems. This is a fundamentally different role, and not every excellent therapist wants it.
Step 1: Define Your Practice Model
There are several models for structuring a group practice, and the one you choose will impact everything from profitability to clinician satisfaction.
W-2 Employment Model
You hire therapists as employees. You pay them a salary or hourly rate plus benefits. You maintain more control over their schedule, clinical approach, and client experience.
- Pros: Greater quality control, stronger team culture, clinician loyalty
- Cons: Higher overhead, payroll taxes, benefits costs, more regulatory requirements
1099 Independent Contractor Model
You bring on therapists as independent contractors. They typically set their own schedules and may use their own therapeutic approaches. You provide office space and referrals in exchange for a percentage of their session fees.
- Pros: Lower overhead, less administrative burden, more flexibility
- Cons: Less control over quality and scheduling, potential IRS classification issues, higher turnover
Hybrid Model
Some practices start with the 1099 model and transition to W-2 as they grow and can afford benefits and payroll infrastructure. Others maintain a mix intentionally.
Important legal note: The distinction between a W-2 employee and a 1099 contractor is determined by IRS guidelines, not by your preference. Misclassification can result in significant penalties. Consult with a healthcare attorney and accountant before deciding.
Step 2: Handle the Legal and Financial Infrastructure
Before your first associate sees a single client, you need these elements in place:
Business entity. If you are still operating as a sole proprietor, it is time to form an LLC or professional corporation (PC/PLLC). This provides liability protection and creates a formal structure for the group practice.
Updated liability insurance. Your malpractice and general liability insurance must cover a group practice. Notify your insurer and update your policy. If you are hiring W-2 employees, you will likely need workers' compensation insurance as well.
Group NPI number. If you accept insurance, you will need a group NPI (Type 2) in addition to each clinician's individual NPI. This allows you to bill under the group practice umbrella.
Updated insurance credentialing. Each new clinician must be credentialed with every insurance panel you accept. Start this process early -- it can take 60 to 120 days.
Employment contracts or contractor agreements. These should clearly outline compensation structure, non-compete clauses (where legally enforceable), confidentiality expectations, termination terms, and clinical supervision arrangements.
Updated HIPAA policies. Your Business Associate Agreements, privacy policies, and data security protocols must account for additional clinicians accessing client information.
Step 3: Set Your Compensation Structure
This is where many group practice owners struggle. Set compensation too low and you will not attract quality clinicians. Set it too high and the practice will not be profitable.
Common compensation models:
- Percentage split: The clinician receives a percentage of the fee collected for each session, typically ranging from 40% to 60%. The practice retains the remainder to cover overhead, administrative costs, and profit.
- Salary model: The clinician receives a fixed salary regardless of caseload. This provides stability but requires careful financial planning to ensure profitability.
- Base plus bonus: The clinician receives a lower base salary plus bonuses for exceeding caseload targets. This aligns incentives and rewards productivity.
When calculating your split, account for all costs:
- Office space (rent, utilities, internet)
- EHR and practice management software
- Insurance billing and administrative support
- Marketing and client acquisition
- Liability insurance
- Clinical supervision time
- Payroll taxes (for W-2 employees)
A general rule of thumb: the practice should retain 35% to 50% of collected revenue to cover overhead and generate profit. If your margins are thinner than that, your compensation structure or overhead needs adjustment.
Step 4: Hire the Right Associate
Your first hire will set the tone for your entire group practice. Choose carefully.
Where to find candidates: Local graduate programs, professional associations, LinkedIn and Indeed, referrals from colleagues, and your own professional network.
What to look for beyond clinical skills:
- Alignment with your practice values. If your practice emphasizes evidence-based approaches, hire someone who shares that commitment.
- Self-motivation and reliability. In a small practice, there is no room for clinicians who need constant supervision or miss appointments.
- Willingness to participate in practice building. Your first associate should be willing to network and contribute to growth -- not just fill a chair.
- Complementary specialization. Ideally, your first hire brings something different -- a new specialty area, population focus, or bilingual capabilities.
Step 5: Build Systems Before You Need Them
The practices that scale successfully are the ones that systematize operations before adding clinicians, not after. Here are the systems you need:
Client intake and assignment. Develop a clear process for how new clients are assigned to clinicians. Consider specialization match, availability, insurance, and client preference.
Scheduling and calendar management. Use a practice management system that allows each clinician to manage their own availability while giving you oversight of the full schedule.
Billing and collections. If you are not already outsourcing billing, seriously consider it. Billing complexity increases substantially with multiple clinicians, especially if you accept multiple insurance panels.
Clinical documentation standards. Establish templates and expectations for progress notes, treatment plans, and discharge summaries. Consistency protects the practice legally and maintains quality of care.
Communication protocols. How will you and your associates communicate about client concerns, scheduling changes, or administrative issues? Regular team meetings (even with just two people) prevent problems from festering.
Supervision structure. If you are hiring pre-licensed clinicians, you are legally required to provide clinical supervision. Even for fully licensed associates, regular consultation meetings support clinical quality and team cohesion.
Step 6: Market the Expanded Practice
Adding a new clinician means you need more clients, which means your marketing must scale alongside your team.
Update your website to feature the new clinician with their own bio page, photo, specializations, and a way for potential clients to request them specifically.
Create or update directory listings on Psychology Today, TherapyDen, and other relevant platforms. Each clinician should have their own profile linking back to the group practice.
Optimize your Google Business Profile to reflect the group practice and include photos of the new team member.
Leverage your existing referral network. Send a warm, personal announcement to referral sources introducing the new clinician and highlighting the populations or issues they specialize in.
Consider niche marketing. If your new associate specializes in an area you do not (e.g., adolescents, substance abuse, or specific cultural communities), create targeted content and outreach for those audiences.
Step 7: Monitor Financial Health Relentlessly
In the early months of a group practice, cash flow can be tight. A new associate may take three to six months to build a full caseload, especially if insurance credentialing is still in progress.
Track these metrics monthly:
- Revenue per clinician: Is each clinician generating enough to cover their costs plus contribute to overhead and profit?
- Client acquisition cost: How much are you spending on marketing per new client?
- No-show and cancellation rates: High rates for a specific clinician may indicate a scheduling, fit, or engagement issue.
- Collections rate: Are you collecting what you are owed? Low collections may indicate billing problems or insurance issues.
- Overhead ratio: What percentage of revenue goes to overhead? As you scale, this ratio should improve over time.
The Mindset Shift: From Clinician to Leader
Perhaps the most challenging aspect of scaling is the internal shift it requires. You are no longer just a therapist -- you are a business leader, supervisor, and mentor. This means learning to delegate, making uncomfortable financial decisions, and having difficult conversations about performance.
The therapists who make this transition most successfully are the ones who seek support from business coaches, peer consultation groups, and practice management consultants who understand healthcare businesses.
Scaling to a group practice is not a leap you take blindly. It is a series of deliberate, well-planned steps that allow you to serve more clients, increase your income, and build something far beyond what a solo practice can achieve.
