What are the first steps in how to start a private practice? 

Let’s start with the essentials. In order to legally, ethically, and functionally begin seeing clients in your new therapy practice, it’s essential to have some foundational components of your business in place. 

This includes things like a: 

Why is networking important for private therapy practices? 

Learning how to start a private practice on the side can sometimes feel lonely. Therefore, cultivating a community you can turn to for support and guidance is key. 

There’s a lot you can learn about how to start a private practice from other entrepreneurs. Joining an entrepreneur group or seeking private practice consulting will provide you with the support and accountability you need. Additionally, having a like-minded community to commiserate and vent with can be comforting, especially in the early stages of private practice. 

You don’t necessarily need to limit your networking efforts to private practice owners in your field or specialty. If you join a group with many different kinds of private practice professionals, you’ll be able to learn tips on how to run your business from unique and different perspectives. 

This could be an opportunity to build referral networks with speech-language pathologists (SLPs), occupational therapists (OTs), as well as with psychiatrists and psychiatric mental health nurse practitioners (PMHNPs)

How much does it cost to start a private practice?

When thinking about how to start a private practice on the side, startup cost is often one of the first thing that comes to mind. 

Costs may include legal or accounting fees, fees for setting up a business entity, initial electronic health record (EHR) system fees, website fees, marketing fees, and more. These costs may vary based on factors like your location, if you choose to have an office or use telehealth, and your services offered. You’ll want to create an estimate of the money you will need to spend before you start generating income.  


How do you find clients for your therapy practice?

Another important step when learning how to start a private practice on the side is determining who your ideal clients are. When you first open your practice, it’s easy to feel pressured to fill your schedule with appointments right away, but taking on every client can actually backfire. 

Finding clients to work with isn’t just about clients choosing you—you also have to choose the people who are best-suited for your style of care. If you want to provide the best results, you need to be the right fit. When you’re not the right fit, it can result in extra work, poor results, and bad reviews for your new practice. 

To avoid these pitfalls, make sure that when you’re thinking about how to start a private practice on the side, you create an authentic therapy brand that reflects the kind of clients you wish to attract. 

If you’re not sure what niche is right for you, begin by thinking about all the clients that you’ve worked with over the years, including in your rotations, at previous jobs, ones you’re currently working with, or the clients you really loved and felt good about helping. 

Where should your therapy practice be located?

After you’ve determined your ideal client, the next step in how to start a private practice on the side is to find your private practice setting. You have a lot of choices, including clients’ homes, your home, a traditional office, or telehealth

Think about how the requirements of each space will work with your business and therapeutic techniques before choosing a setting

If you decide to use telehealth in your private practice, you’ll want to ensure you’re using a secure, HIPAA-compliant platform that has all of the features you need—including a virtual whiteboard to increase engagement with clients and the ability to customize your background for privacy.

For an in-person office space, not only will you have to weigh the cost of leasing or renting it, but you will want to ensure it’s accessible, HIPAA-compliant, and in an ideal location. You’ll also want to think about decor and artwork to make your office inviting and calming for clients.

Should you accept health insurance? 

When going through the steps of how to start a private practice on the side, an important question to consider is whether or not you will accept health insurance through a specific insurance payer panel.

There’s no one right way to bill clients in your private practice, but there are some considerations for insurance vs. private pay, like the demographic makeup of your community or neighborhood and what your competition is doing. 

Because insurance company websites can help with your marketing and visibility to their subscribers, one of the benefits to accepting insurance in your therapy practice is you may get a steady stream of clients without the need to do much of your own marketing.

How do you choose an EHR solution?

Once you’ve completed the fundamentals for how to start a private practice therapy business and are ready to start seeing clients, you’ll want to decide on an electronic health record (EHR). 

An EHR can help you manage your time efficiently and streamline administrative tasks. 

Carefully evaluate your EHR solution options, and consider the following:

How do you market your therapy practice?

You’ll likely need to market your practice if you’re thinking about how to start a private practice on the side, and there are various tactics you can use.

First, ask yourself—are you an introvert or an extrovert? 

Introverts may work better in one-on-one settings, so creating a list of professionals in your area that work with your ideal client is a good first step. Then, send an email introducing yourself and inviting them to meet up to learn more about their professional experience and practice. Doing so is important for networking and can help you receive client referrals, and they may also have advice on how to start a private practice therapy business. 

If you’re more of an extrovert, you should still reach out to individuals in your area, and you may also want to consider giving lectures or hosting meet-ups for professionals in your area. 

Social media marketing is another avenue you may want to consider. An active online presence can increase your visibility with potential clients, build trust and loyalty, and improve client retention when working through the steps of how to start a private practice on the side for mental health. 


How do you continue to grow a therapy practice?

Now that you’ve learned how to start a private practice on the side for mental health, you may be considering making the leap to full-time or hiring staff for your practice. But first, it’s important to take a close look at your budget and make sure you are meeting your goals.

Growing your private practice will take time, however, by following these steps on how to start a private practice therapy business, you can make the transition seamlessly.
