Therapist in New Jersey
I'm a licensed therapist serving clients throughout New Jersey — virtually across the state, and in person for those close enough to my Center City Philadelphia office.
If you're in South Jersey — Camden, Cherry Hill, Haddonfield, Collingswood, Moorestown — you're minutes from my office, and coming in person is a real option. If you're farther out, or you'd simply rather meet by video, we can do all of it online. Either way, my practice is built around high-functioning adults who are managing a great deal capably and are nonetheless stuck on something they can't work through alone.
Philadelphia is closer than you think
For a lot of South Jersey, "the city" is Philadelphia. You may already cross the river for work, dinner, or the airport. My office at 255 S 17th Street, near Rittenhouse Square, is a short drive or a PATCO ride from most of Camden County — which makes me one of the few things you don't have to choose between doing virtually or locally.
That proximity is the whole point. Plenty of my New Jersey clients started virtual and came in when a particular stretch of work warranted being in the room, then went back to video when their schedule tightened. You get the convenience of telehealth without giving up the option of sitting down together when it matters.
And because I'm right across the river rather than a state away, the pace of Philadelphia life — the same demands you already live near — isn't something I have to be briefed on.
What brings New Jersey clients to therapy
The themes I see most often:
Work that has quietly taken over. A demanding career — in Philadelphia, in the suburbs, or remote — that expanded to fill everything, until it became hard to tell where the job ends and you begin.
Achievement that stopped satisfying. You did what you set out to do, and the payoff didn't land the way you expected.
Relationships that have drifted. The commute, the hours, the logistics of a full life — and a partner who's started to feel more like a co-manager than a person you're close to.
Anxiety running underneath. Often long-standing and unnamed — trouble switching off, a low background hum that only quiets when you're finally away from it all.
Transition. A move, a new role, a marriage or its end, a child, a loss. The shifts that unsettle even people who are used to handling things.
"Matt was helpful with everything from romantic relationships to toxic work relationships to family struggles. He asked the right questions at the right moment as well as just listened when it was what was needed."

How I work
I take an eclectic, evidence-based approach — matching the method to the person rather than running everyone through the same protocol. Depending on what you're working on, that may include:
Cognitive Behavioral Therapy (CBT) for anxiety, rumination, and unhelpful thought patterns
Acceptance and Commitment Therapy (ACT) for values clarification and psychological flexibility
Internal Family Systems (IFS) for internal conflict and self-criticism
Emotion-Focused Therapy (EFT) for accessing what's underneath
Psychodynamic work for long-standing relational patterns
Exposure and Response Prevention (ERP) for OCD
Positive psychology for meaning, purpose, and strengths — I hold a master's in this specifically
I'm known for being direct. Clients tell me they appreciate that I'll say what I actually think rather than nodding.
What I help with
Anxiety & Stress— practical tools to quiet the noise and feel more in control
Depression & Burnout — support for low mood, fatigue, and finding your way back
Career & Identity— clarity when work feels stuck or unfulfilling
Life Transitions — steadier footing through change
Relationships — individual work on patterns that keep repeating
Men's Therapy — stress, self-doubt, and the pressure to hold it together
OCD Treatment — evidence-based care for intrusive thoughts
Sessions
New Jersey sessions are available virtually across the state, and in person at my Center City office for clients close enough to travel. Virtual sessions run over VSee, a HIPAA-compliant secure video platform.
A 60-minute intake to start, then 50-minute sessions weekly or biweekly. Daytime and evening hours available, with evenings limited. In-person availability is daytime and evening on weekdays; I don't hold in-person hours on Saturdays, though Saturday virtual sessions are sometimes available.
For virtual sessions, you need to be physically located in New Jersey — or another jurisdiction where I'm licensed — at the time of the session.

FREQUENTLY ASKED QUESTIONS
-
If you're in South Jersey, likely yes. My office is near Rittenhouse Square in Center City, a short trip from much of Camden County. Many New Jersey clients mix in-person and virtual depending on the week. Farther from Philadelphia, virtual is the practical choice.
-
I'm an out-of-network provider. I don't bill insurance directly, but many clients receive partial reimbursement through out-of-network benefits, and I provide a monthly superbill for submission. My out-of-network explainer covers how to check your benefits before you commit.
-
For a virtual session you need to be physically located in New Jersey (or another state where I'm licensed) at the time of the session.
-
I'm also licensed in Pennsylvania, New Jersey, Maryland, Virginia, and Washington State. If you'll be somewhere else, we'll plan around it.
-
Email, call, text or message us. From there, we'll schedule a free 30-minute video consultation. The consult is conversational — you'll have a chance to share what's going on, ask questions, and get a feel for how I work. If it seems like a good fit, we'll schedule your first full session from there.
Getting started is simple
Most people begin with a free 30-minute video consultation. It's an informal conversation — what's going on, what you're hoping for, and whether we're a good fit. No pressure.
If we move forward, the first session is a 60-minute intake. After that we typically meet for 50-minute sessions weekly or every other week.
