At Downtown Psychological Services, we have designed a simple process for connecting you to the right therapist.  After you contact us by phone or email, we will schedule you for a free, 15-minute phone consultation to find out what brings you to therapy and to answer any questions you have about our practice.

Following that discussion, we will assign you the therapist who best fits your needs and preferences. We believe, first and foremost, that comfort with your therapist is of the utmost importance to a successful therapeutic relationship. In rare instances, you may feel the dynamic is not working for you after a few meetings.  If this arises, we will help you find another therapist in our practice or elsewhere.  Our main goal is to ensure the relationship is right for you so that you can connect with and open up to your therapist so you get the most out of the process.

Michael C. Klein, PhD

I am a clinical psychologist with 13 years of experience treating adults for a variety of concerns in psychotherapy and psychoanalysis. I am a Co-Founder, Executive Director, and Senior Psychologist at Downtown Psychological Services, PC, a psychotherapy practice specializing in adult treatment with a focus on mental health and academic issues on college campuses. I completed my doctorate in clinical psychology at Long Island University - Brooklyn campus in 2006 and began working as a staff psychologist at NYU’s Counseling and Behavioral Health Center.

During this time, I was co-director of a national project aimed at improving depression care on college campuses ( I soon realized how much I enjoyed working with young adults and opened a private practice where I could do more in-depth psychotherapy work. While building the practice, I continued to advance my knowledge and skills through post-doctoral training at the Institute for the Psychoanalytic Study of Subjectivity (IPSS). I recently graduated and became a certified psychoanalyst in 2019. I continue to focus on working with young adults, many of whom are undergraduate and graduate students. I have treated hundreds of students and other adults utilizing short-term and long-term psychotherapy approaches. I have a particular interest in helping highly creative people and competitive individuals who actively strive to master a field of interest or domain (e.g. cooking, writing, artists, athletes) and attain their goals of peak performance.



Melissa Tihinen, LCSW

I’m a Co-Founder of Downtown Psychological Services where I also serve as the Director of Operations and a Senior Therapist. Therapeutically, I strive to assist individuals and couples in understanding how early attachment dynamics in their families impact their current-day coping strategies, relationships, and way of relating to the world.  I have extensive experience working with adults on various concerns including life transitions, depression, anxiety, sexual assault/abuse, relationship difficulties, trauma, LGBTQ+ concerns, and substance use.

As a Certified EFT Couples Therapist, I help couples overcome conflict and distress arising from negative cycles of interaction. I work to facilitate truthful conversations that involve both partners recognizing their contributions to the dynamic and learning to express their wants and needs in more productive ways.

In working with individuals who have experienced trauma,  I will often suggest that we utilize Somatic Experiencing, which focuses on how the body, especially the nervous system, metabolizes trauma.  In SE, we work to pay attention to how the body holds trauma in an attempt to help the nervous system re-regulate.

I hold a Master of Social Work from New York University and a Master of Arts in Public Policy and Gender Studies from The George Washington University.  After receiving my MSW, I continued my post-graduate work in psychoanalysis at the Psychoanalytic Psychotherapy Study Center.  Prior to becoming a therapist, I worked in student affairs at several universities and enjoy working with undergraduate and graduate students.  Additionally, I worked as an advocate for survivors of sexual and intimate partner violence for over 15 years in a variety of capacities.


Rachel Aedan, LMSW

There is suffering in life. Yet, within each of us exists the possibility of living in ways that feel less anguished, more fulfilled, and more deeply connected to ourselves and others. Therapy can be a meaningful method that moves us towards whatever our goals may be by tapping into our unrealized potential.

I aim to provide a space that allows for the development of psychological growth while also offering tools to reduce symptoms and enrich everyday life. My clinical training includes work at the Psychoanalytic Psychotherapy Study Center where I explored with clients how attachment dynamics and narratives of the past play a role in patterns of thought and behavior. I bring this attachment based lens to working with couples as well.

I have additional experience utilizing trauma-informed interventions with child and adult survivors of physical and sexual abuse, as well as depression, anxiety, and grief. My work integrates these approaches and also draws on my training as a meditation teacher where I have studied how mindfulness and compassion practices affect the brain and nervous system.

I hold a Master of Social Work from Fordham University and a Bachelor of Arts from Hunter College. I welcome working with adults navigating various concerns around trauma, family of origin, relationships, anxiety, panic attacks, depression, grief, and existential questions.


Alex Buckner, PsyD

I am a staff therapist at Downtown Psychological Services and pursued my undergraduate education at Tulane University in New Orleans, shortly after Hurricane Katrina struck. This experience in New Orleans was invaluable in helping me see the suffering in many parts of the U.S and all over the world. This suffering, along with my desire to help people find their way out of suffering, inspired me to become a psychologist.

I completed my doctoral studies at Yeshiva University’s Ferkauf Graduate School of Psychology, where I received my doctorate degree in clinical psychology. During my time at Yeshiva, I gained extensive experience in individual, couples, and family therapy, as well as psychological testing and assessment. I have worked with individuals at NYU’s counseling center, multiple community mental health clinics, and both short-term and long-term psychiatric hospitals.

I have received thorough training in DBT and specialize in treating individuals with borderline personality disorder using this approach. I have received thorough training in psychodynamic therapy and draw from this approach in treating individuals with issues such as identity formation, emerging adulthood, relationships, LGBTQ concerns, substance use disorders, and anxiety and depression. In addition to individual treatment, I completed training in Emotionally-Focused Couples Therapy and work with couples to identify and resolve unhelpful patterns within their relationship.

Brooke Greene, PhD

I find therapy to be a valuable space for reflection, connection, and growth and embrace the opportunity to construct such a space with my clients. I bring a warm, empathetic presence and a desire to understand my clients deeply as we work together towards the change they desire in their lives.

I hold a PhD in clinical psychology from the City University of New York Graduate Center. In addition to work in hospitals and community mental health centers, I have five years of experience working in college counseling centers, including (among others) those at New York University, Fordham University, and Pace.  In my work with individuals, couples, and groups, I draw upon psychodynamic, systemic, and skills-based approaches to increase clients’ resilience and sense of fulfillment in multiple aspects of their lives. 

I enjoy working with clients presenting with a wide range of concerns including depression, anxiety, relationship challenges, grief, sexual assault/abuse, substance use concerns, traumatic/difficult past experiences, and concerns related to navigating identities of all types. Offering an environment that is affirming to LGBTQ+ clients is particularly important to me.

In addition to my training in psychology, I hold a PhD in political science from Columbia University. My background in political science reflects my interest in the impact of political and social structures on the lives of my clients. I am also well-acquainted with the challenges of academic life and eager to assist students navigating related concerns.


Joshua Halpenny Nguyen, LMSW

I  want to help people in their personal journeys of self-discovery, self-exploration, and healing.

Prior to becoming a therapist, I worked in a variety of roles including as a clothing designer, a personal trainer, and a safer-sex educator for queer Asian Pacific Islander men. The culmination of all of these experiences led me towards becoming a psychotherapist, as I learned about how individuals see themselves, how they understand themselves in the world, and how they relate to others.

I enjoy working with adults of various backgrounds and identities. I feel especially comfortable  working with people of color and LGBTQ+ individuals and couples around identity, sexuality, coming out, and relationships. As a queer man myself, I have my own experiences to draw on around these areas. Additionally, I understand how important connection is in the therapeutic alliance and strive to create a comfortable environment for the individuals and couples I see.

Sometimes life teaches us that relationships are painful, difficult and just downright confusing. The experience of opening up in therapy can be daunting, so it is important to me to create a collaborative process in which we work together to establish what our working relationship looks like in our sessions..  I treat every client I see with careful attention to their individual needs. Additionally, I hope each client can discover where they would like their journey to lead through our work together as I believe knowing that is the key to uncovering our best lives.


Diana Liao, LMHC

I believe that healing and growth happen when one is truly heard.

As a therapist, I can provide a safe and nonjudgmental space to support this process and help you move past fears and obstacles that may be getting in the way of your success and happiness.

I help adults work through life transitions, as well as challenges related to school, career/finances, relationships, identity, self-esteem, anxiety, depression, and trauma. As a second generation Asian-American, I’m especially attuned to issues of belonging and marginalization, and the complexities that arise from navigating cultural differences.

I’m dedicated to helping people achieve goals such as deepening self-awareness, overcoming unhelpful patterns, learning effective coping methods, and building emotional resilience. Depending on your needs, we’ll explore approaches from the insight-oriented and solutions-focused to the philosophical and mindfulness-based. Teletherapy is also an option.

Besides my formal training as a mental health counselor, I also have a background in advertising, marketing, and photography. I continue to be inspired by the power of narrative in therapeutic work and would be honored to help you reshape your life story to create more balance, meaning, and fulfillment.


Jessica LaHood, LCSW

I deeply believe in each of our innate drives toward healing and wellness. At times we need support to find our way along this path; this is where therapy can be an essential tool. I employ a collaborative approach to support the development of curiosity and compassion for one’s whole self. In therapy we tune into the body’s wisdom, foster acceptance of ourselves in the present moment, and reshape narratives of our past.

I am a psychotherapist with nearly a decade of experience in the field. My background is in treating adult and child survivors of trauma, as well as those experiencing anxiety, depression, eating disorders, and distress related to life transitions.

I have been a staff therapist with Downtown Psychological Services since 2017. Prior to this, my experience included work as a trauma therapist at Safe Horizon Counseling Center, where I utilized evidence-based treatment modalities to address the impact of trauma on individuals. I also trained as a psychodynamic therapist at the Karen Horney Clinic, where I supported individuals’ ability to draw insight into the ways their  past impacted their present.

In addition to my psychotherapy background, I draw from training as a yoga instructor at Abhyasa Yoga Center and in Mindfulness Based Stress Reduction at Mindful Harlem to support those I work with in reconnecting with their bodies. I also integrate into my work Sensorimotor Psychotherapy, a body-oriented talk therapy aimed at developing mindfulness of our somatic responses, building internal resources and processing traumatic memory.

Alexandra Robbins, LCSW

I believe you are the expert in your own life.  My approach to therapy is collaborative, and together we will work to explore the aspects of your life that are most important to you.  Understanding that New York City can be a challenging place, I always strive to cultivate a warm, caring, and safe space that is judgment-free to help my clients explore the depth of their identities and develop into the best version of themselves. Additionally, I have a deep appreciation for dreams and often use dream work to explore aspects of the psyche to expand awareness of oneself. I believe that through a compassionate and supportive therapeutic relationship, lasting change is possible.

I joined Downtown Psychological Services P.C. as a Staff Therapist in 2015 and hold a Masters of Social Work from New York University and a B.S.Ed from The University of Miami where I studied psychology and education.  I am also currently completing a postgraduate certificate in psychodynamic psychotherapy from The Institute of Contemporary Psychotherapy.

I have experience providing psychotherapy to various populations of adults, including those with severe mental illnesses, people working through substance misuse, concerns about body image, people from the LGBTQ+ community, and both undergraduate and graduate students with a variety of presenting concerns.  


Maureen Sheridan, LMSW

I am passionate about helping adults across the racial, ethnic, gender, age, and socioeconomic spectrum deal with difficulties ranging from trauma, depression, anxiety, and sexual assault/abuse, to relationship conflict, intimate partner violence, and significant life transitions. I have a particular interest in women’s health and parenthood and have completed post-graduate training specializing in body image concerns and eating issues and am currently pursuing a certificate in maternal mental health.

My style can be best described as compassionate, interactive, and direct.  I draw from a variety of perspectives including psychodynamic, relational, trauma-informed, and dialectical behavioral therapies (DBT)..

I hold a Master’s Degree in Social Work from Rutgers University and a Master of Science in Higher Education from Syracuse University. I have continued to advance my knowledge through various post-graduate trainings through the Manhattan Institute for Psychoanalysis, The Linehan Institute, and the Women’s Therapy Centre Institute.

Stephanie Sorensen, PsyD

I am a Staff Psychologist with Downtown Psychological Services. I hold a doctorate in Clinical Psychology from Yeshiva University.

Over the course of my training and career, I have worked with individuals, couples and families in inpatient, day program, and outpatient settings, including Montefiore Medical Center, Long Island Jewish Hospital/Northwell Health, St. Luke's Hospital, Mt. Sinai-Elmhurst Hospital, Marymount Manhattan College, and UWS Therapy Group. Prior to becoming a psychologist, I engaged my passion for literature through a career in book publishing. I am interested personally and professionally in the creative process. I am an avid reader and an appreciator of dance and visual arts.

My overarching goal is to help people make changes in order to shape their lives in accordance with their values. In my work with individuals, I consider diagnoses such as anxiety and depression within the context of current life stressors, including major transitions such as career changes, relationship beginnings and endings, parenthood, loss, or adverse or traumatic events.

My approach in working with couples is to consider each individual's contributions and reactions in negative interactions, and facilitate the expression of needs and empathic responsiveness.

My manner is warm, engaged, flexible and solution-oriented. I use systemic, existential, interpersonal, attachment-oriented and cognitive-behavioral approaches. I enjoy working with young adults who are seeking to create their own path, overcome painful experiences from the past, or improve their relationships with family and friends.
