Reaching out is hard, especially if you've already tried therapy before and it didn't quite get you where you needed to go. I want you to know that doesn't mean something's wrong with you, it usually just means the approach wasn't the right fit. I've spent over a decade working with people carrying trauma and addiction, adults and teens both, and what I care about most is helping you feel truly understood, maybe for the first time, before we even get to the work of healing.

My name is Lori Torre, and I am a Licensed Clinical Social Worker. Since graduating from Stony Brook University in 2009 I have had a variety of experiences working in the mental health field including mental health housing, a community clinical setting and private practice. I have experience working with clients who experience struggles related to depression, anxiety, family dynamics, relationships and trauma. I truly love what I do, and I am passionate about helping others.

I believe prioritizing mental health is key to stability in life. I know there is a better world out there and people need the tools to connect with their upmost insight for mental well being. In this field I am always eager to research and find healing processes to tailor the need of each individual.

Do you worry about what tomorrow holds? Overthinking about events from the past? If you want to learn to experience the present moment, you have come to the right page. My name is Danielle and I specialize in Anxiety, Depression, and PTSD. In addition to those specialties, I support clients through a wide range of challenges including stress management, life-transitions, and self-esteem issues. I strive to create a relaxed, authentic, non-judgmental therapy environment; So, don’t be surprised if you are welcomed by a woman in jeans and sneakers. I believe the goal in therapy is for each individual to reach their highest potential.

I’m Linda Orji, a Board-Certified Psychiatric Mental Health Nurse Practitioner (PMHNP) with over Eleven years of experience in health care. I earned my Master of Science in Nursing from the University of Rochester in Rochester, NY. Over the years, I’ve had the privilege of caring for individuals with both medical and psychiatric conditions, which deepened my understanding of the powerful connection between the mind, body, and overall well-being.

I earned my PhD in Clinical Psychology in 2002. Having worked in healthcare and academic settings, I appreciate being part of a treatment team and am available to coordinate care with other providers when beneficial. Rather than see 'how many problems' a person may be facing... I see 'how many ways things can get better'. I value working with folks to see their puzzle from a different angle and to use tools to clarify, change and improve the picture.

I’m Dr. Joseph Yanni, a licensed psychologist who works with teenagers, college students, young adults, adults, parents, and families navigating anxiety, ADHD, emotional regulation, school and college stress, relationship challenges, and life transitions. I earned my Psy.D. in School Psychology from Fairleigh Dickinson University and continue to work as a school psychologist, supporting students with emotional disabilities in a specialized educational setting. This experience has given me a practical understanding of how emotional, academic, social, family, and developmental concerns often overlap.

I use a collaborative, practical, and integrative approach that draws from Cognitive Behavioral Therapy (CBT), psychodynamic therapy, humanistic and person-centered therapy, behavioral strategies, and lifestyle-based interventions. I believe therapy should be individualized rather than following a one-size-fits-all model. Together, we work to better understand what is contributing to the concern, build practical coping skills, strengthen relationships, and develop realistic strategies that create meaningful change.

I work especially well with teenagers, college students, young adults, and parents navigating the transition from adolescence into adulthood, while also supporting adults and families facing anxiety, relationship concerns, and other important life challenges. I provide in-person therapy in Scarsdale and Pleasantville, along with virtual therapy throughout New York State.

I have a particular passion for working with men, especially guys in their 20s and 30s. A lot of the young men I see are dealing with something the research is only now catching up to — an erosion of in-person connection, a sense of drift, and a shortage of spaces where they can actually say what's going on. I'm genuinely excited and motivated by this work because I believe this generation of men needs — and deserves — real support. That said, I also welcome clients navigating anxiety, discouragement, depression, workplace stress, relationship dynamics, and life transitions of all kinds.

I'm a Brooklyn-bred Psychotherapist and earned my LCSW in 2009. I previously worked in the corporate world, and understand pressure, ambition, career transitions, and what it feels like when the thing you've built your identity around stops fitting. Since becoming a therapist, I've worked in hospitals, outpatient clinics, substance abuse treatment, and psych rehab before settling into a private practice where I'm focused on the work I care most about.
