Hidden Gems: Meet Carl Fleisher of Stratus Mental Health Center

Today we’d like to introduce you to Carl Fleisher.

Alright, so thank you so much for sharing your story and insight with our readers. To kick things off, can you tell us a bit about how you got started?
It’s remarkable how life can pivot in a moment. I can still picture sitting in AP Psychology class in high school. One day, our teacher announced that a “psychic friend” would create individualized psychological profiles for each of us, based on a short questionnaire—questions like choosing a spirit animal. Weeks later, he handed out the profiles, face down for privacy. When I read mine, I was stunned. It felt uncannily accurate. How could a psychic know all of this, based on my made-up answers to goofy questions? As everyone started reading, the room fell silent; the other profiles were clearly hitting home, too.

The teacher asked for a volunteer to read their profile aloud. No one raised their hand. (Read that? To a roomful of judgmental teenagers?) So, he just picked one up and began reading. Within seconds, we realized the trick: every student had received the exact same profile. The lesson was unforgettable—what felt deeply personal turned out to be universal, even scientific. I was hooked; in hindsight, I realize that day marked the beginning of my career.

I majored in psychology at Haverford College. I was glad to be back in Philadelphia, where I’d been born. As I explored paths in mental health, I was drawn to two things: working directly with people – research wasn’t in my DNA – and psychotherapy. After conversations with psychiatrists showed me that medical school wouldn’t preclude training as a therapist, but instead would add complementary skill in prescribing, that was all I needed to hear.

I moved back to Boston for medical school at Harvard. It was both humbling and exciting. One high point of med school was doing a rotation with my father, a pediatrician. Although I considered following in his footsteps, brain problems were always what was most compelling to me. Ultimately, I chose child psychiatry because it combined what mattered most to me: the mind and families.

Even in med school, certain moments shaped my professional identity. During a surgical rotation, I helped to care for a woman who didn’t speak any English. Moved by our inability to communicate, I taught myself a sliver of her language—enough to ask basic post-operative questions. That experience crystallized a central value for me: patients are people, full stop.

I matched at UCLA for psychiatry training. There, surrounded by talented colleagues, I felt I’d finally arrived at the work I was meant to do. At the time, UCLA offered training in a psychotherapy approach called mentalization (a scientific term for curiosity). Curiosity helps people feel genuinely understood, reducing mistrust and opening the door to therapeutic change. I’m deeply indebted to Dr. Robin Kissell and other mentors for helping me develop this into a core professional skill.

Another pivotal moment was learning from Dr. John Gunderson, one of the most influential figures in the modern understanding of borderline personality disorder (BPD). He believed that all patients with BPD deserve clinicians trained to treat them, not only those who could access specialized care. His commitment to careful diagnosis and effective treatment of personality disorder sparked a broader passion in me for measurement-based care and for the science of psychotherapy.

People often tell me that psychiatry seems like it is simply listening to problems. What they might call problems, though, I see as suffering that needs decoding—finding patterns, understanding needs, and easing the emotional obstacles that make simple changes seem out of reach.

I’m sure it wasn’t obstacle-free, but would you say the journey has been fairly smooth so far?
Working in the mental health system definitely has its share of struggles. Watching anxious young adults seek effective therapy but not find it, or hearing about teenage patients cycling through a therapists without benefit, is a troubling pattern. I’ve seen colleagues tackle this challenge in many different ways. For me, I became a student of what makes psychotherapy work: what approaches work best, which therapist factors predict the best outcomes for which problems, and other questions. Watching families confront serious barriers to care also nudged me to look beyond clinical work alone. Learning how to lead clinical teams and work on the management side of healthcare felt unfamiliar and uncomfortable at first, but I was motivated to build those skills because too many people were being undertreated. I felt a responsibility to influence both access and quality at a broader level.

As a psychiatrist who practices psychotherapy, I have also spent much of my career straddling two professional worlds, which can feel like belonging partly to two different families. I feel at home among therapists, discussing patients’ relationships and emotions, and also among psychiatrists thinking about biology and brain anatomy. At times, I’ve struggled to bridge this divide, to find communities that support me so that I can support my patients. Working across a range of settings (academia, a startup, public mental health and most recently private practice) wasn’t a straight line, but it connected me with brilliant colleagues who gave me confidence in my dual professional identity. That has allowed me to define my own niche, combining both academic and clinical pursuits, with more flexibility and faster decision-making than large organizations can offer.

Founding a group practice has been both the most challenging and the most fulfilling chapter of my career. Building something new and supporting others requires discipline, patience, empathy and self-reflection. The reward is the ability to practice medicine in line with my values. I take pride in striving to provide excellent care for patients, while preserving some time to mentor students, teach clinicians, and design programs that prioritize quality. It hasn’t been the simplest path, but it’s one that suits me, and one I’m grateful to be on after years of effort and learning.

Alright, so let’s switch gears a bit and talk business. What should we know?
Stratus Mental Health Center is a multidisciplinary clinic for children, adolescents, and young adults. We provide care across a wide range of emotional and psychiatric concerns, from common challenges to complex, long-standing conditions. Our goal is to help people make progress that yields true change in their lives and to monitor closely for signs that treatment is not helping. When that occurs, we adjust our approach so that patients do not feel adrift or left to manage their care on their own.

Since our inception, we have offered expertise in treating trauma, self-harm, and personality-related difficulties, areas in which people too often receive fragmented or incomplete care. In addition, we offer specialized programs for anxiety, obsessive-compulsive disorder and early childhood behavioral difficulties. Another program offers evaluation and care for youth and young adults with diverse gender identities. Overall, our practice is defined less by any narrow expertise and more by a commitment to providing treatments that are evidence-based, carefully delivered, and accountable.

Accountability, in the form of routine progress monitoring, is one of our core practices. We measure symptoms, quality of life, and patients’ experiences of care as a routine part of evaluation. We track changes in symptoms and satisfaction regularly, and then use that feedback to guide treatment decisions in real time. We combine these quantitative measures with clinical judgment and with patients’ or parents’ own impressions to provide clear indicators of improvement. We pay close attention to whether care is producing meaningful functional improvement — and we make changes when it is not.

What I am most proud of is the culture we have built. Our clinicians work closely together, learn from one another, collaborate with the broader team (families, primary care, educators, or others involved in a patient’s care) and take responsibility for tracking progress. Because no clinician gets it right every time, we have created systems that help us recognize when progress slows. At that point, we respond by refining the diagnosis, adjusting the treatment plan, or connecting a patient with a colleague who may be a better fit.

Stratus is a place where human connection and deep understanding matter, but they are not enough on their own. People come to us because they are suffering, and they deserve care that is not only compassionate but also capable of fostering measurable recovery.

What were you like growing up?
I grew up in the Boston area with a twin sister and an older brother. My parents are very close with their siblings, so I was lucky to build great relationships with my cousins as well. I’ve been fortunate to have a close-knit family.

Personality-wise, I have always been an optimist. As a child, I was studious—nerdy, you could say—and somewhat shy. I loved reading, especially science fiction like Star Trek and detective novels such as The Hardy Boys.

I also loved sports. I somehow didn’t realize until fifth grade that kids could play tackle football, but once I did, I asked my parents that same day to sign me up for the local Pop Warner league (before concussion risks were widely understood). I kept playing football through high school. At that age, I also started a club for students who played the card game Bridge. The club met just before football practice, which meant I often arrived late to the field. That didn’t exactly win me points with my coaches, but I enjoyed both worlds and stuck with them.

In high school, I also began playing volleyball. I continued through college and then switched to beach games when I moved to Los Angeles for residency. Living on the West Coast deepened my love of the outdoors, and I became an avid hiker and camper. I was active in the Sierra Club for many years, which is where I met my wife.
