5 Steps to Find Out How Many Clients Need You
I was presenting to a room full of therapists a few years back — at a Washington Association of Marriage and Family Therapists event — and I made a bold claim: "There are more than enough clients to fill every single practice in this room. And every other private practice therapist in your city."
A therapist pulled me aside afterward and asked the question I get asked constantly: "But how do you actually know that?"
Fair question. So let me show you exactly how I know — and how you can find out for your own city, your own specialty, and your own market in about an hour.
Because here's what I've seen over 15+ years of coaching therapists: the scarcity mindset is almost never supported by the data. Therapists hold back from starting or growing their practice because they're afraid there aren't enough clients, that the market is saturated, that someone else already has the corner on their niche. And the fear is almost always wrong.
Let's look at the numbers instead.
Step 1: keyword research — what people are actually searching for
Use Google Keyword Planner to see what your community is searching for
Google tracks what people search for — and they make that data available to anyone with a free Google account through Google Keyword Planner (at ads.google.com/keywordplanner). You don't need to run ads to use it. You just need a Google account.
Here's the exercise: search for your city or metro area and look up how many people are searching for terms related to mental health and therapy each month. Search for terms like:
- anxiety therapy [your city]
- therapist near me
- couples counseling [your city]
- depression therapist
- trauma therapy [your city]
- postpartum depression support
- [your specialty] therapist [your city]
Now do the math. If 500 people per month are searching for couples counseling in your metro area, and even 10% of them are ready to actually book with a therapist, that's 50 new couples per month looking for someone like you. How many could you realistically serve in a year?
Step 2: population data — the math you're not doing
Look up your city's population and do some back-of-napkin math
Search for the current population of your city or metro area. Then apply what you already know from your clinical training about prevalence rates.
What percentage of people in your area struggle with anxiety? With depression? With relationship distress? With trauma? With substance use? You know these numbers — you studied them. Apply them to the population in front of you.
If your city has 400,000 people and conservative research suggests 18% of adults experience anxiety disorders in a given year, that's roughly 72,000 people in your city alone. Your full caseload is 20-25 clients. The math is not close.
Now factor in: how many of those 72,000 people have access to affordable, culturally competent care right now? How many have found a therapist they actually connect with? How many have given up because they couldn't find anyone who felt right?
Step 3: local trends — what's happening in your community right now
Pay attention to what's happening where you live
Every city has its own texture — its own stressors, industries, demographics, and community struggles. And most of those struggles translate directly into therapy demand.
Is your city growing rapidly? New residents often arrive without any local support system — and frequently need help building one, managing transition stress, and finding community. Is your area dealing with a particular economic shift? A healthcare or tech hub brings high-achieving professionals with burnout and anxiety. A community impacted by layoffs brings financial stress, relationship strain, and depression.
What's in the local news? What are people in your community struggling with that isn't being talked about enough? What are the search terms people in your area are typing that nobody is ranking for?
Search your specialty as if you were a client looking for help. Does anyone come up? Are there gaps in the market that your specific background and experience could fill?
Step 4: incidence and prevalence data — use what you already know
Pull the research on your specific population
If you have a specialty, you already know the prevalence data. Use it. Put actual numbers in front of yourself.
How many people per 1,000 experience the issue you specialize in? Apply that rate to your city's population. Write the number down. Then calculate how many therapists in your area explicitly specialize in that issue — check local directories, do a Google search, look at who's showing up in Psychology Today for your zip code.
In almost every specialty, in almost every market, the gap between the number of people who need help and the number of qualified, available therapists is enormous. The problem is rarely supply. It's findability — which is a solvable problem.
- Postpartum mental health: The CDC estimates roughly 1 in 5 mothers experience perinatal mood and anxiety disorders. How many perinatal specialists are in your city?
- Trauma and PTSD: SAMHSA data consistently shows trauma as one of the most underserved mental health needs in almost every community.
- Couples work: The American Psychological Association has cited that roughly 40-50% of marriages end in divorce — and most of those couples never saw a therapist.
Pick your specialty. Do the math. The scarcity isn't where most therapists think it is.
Step 5: availability — be the client
Search for yourself as if you were someone who needed you
This is the exercise that changes things for most therapists I work with. Open an incognito browser tab, go to Google, and search for what your ideal client would search for if they were looking for a therapist like you. Use the words they would use — not clinical language, their language.
What do you find? Is the market full of therapists who specialize in exactly what you do, who write the way you write, who serve the exact population you want to serve? Or do you find a handful of generic directory listings, some Psychology Today profiles, and a lot of gaps?
Notice I'm calling this "availability" and not "competition." I've stopped using that word when talking about private practice, because it implies a scarcity that the data almost never supports. The question isn't who else is out there. It's whether the right people can find what they need — and whether you're making it possible for them to find you.
What the data actually shows
Every time I've done this exercise with a therapist — in a group presentation, in a 1:1 coaching session, in Business School for Therapists — the conclusion is the same: there are more than enough people who need support. In almost every city, in almost every specialty, in almost every market.
The therapists who struggle to fill their practices aren't struggling because the clients don't exist. They're struggling because the clients can't find them. Your website isn't showing up. Your message isn't resonating. Your niche isn't clear enough for the right person to recognize themselves in it.
That's not a market problem. That's a marketing and visibility problem. And those are solvable.
The question isn't "is there room for my practice?" There almost certainly is. The question is "can the people who need me actually find me?" That's where the work is — and it's work you can learn to do.
Once you've done this exercise and seen the demand that exists in your market, the next step is making sure the people searching for what you offer can actually find you. That's an SEO problem — and it's more learnable than you think.

Low search volume doesn't necessarily mean low demand — it can mean the population you serve isn't using clinical language to search. Try searching the way your clients would describe their problem, not the diagnostic term. "I feel like a failure as a mom" gets searched far more than "postpartum depression therapist." Understanding your clients' language is both a marketing and an SEO skill.
The general "therapist" market can feel saturated because that's where everyone competes. The more specific you get — by specialty, by population, by approach — the less saturated it becomes. A therapist who specializes in anxiety for first-generation college students, or grief for parents who have lost a child, or burnout for emergency responders is operating in a very different market than "general therapist near me." Specificity is your competitive advantage.
Make sure the people searching can find you. That means a clear website with copy that speaks to your ideal client, a Google Business Profile that's complete and current, and a content strategy that meets people where they are. Our SEO guide for therapists covers all of this in detail.
