Who We Are

City and Country CBT is a small group practice founded by Dr. Sameena Groves and Dr. Sarah Trosper Olivo. We are licensed psychologists who trained and worked together at the NYU Child Study Center before deciding to start a private practice.

Inside the Office
I’m a licensed clinical psychologist who believes that empathy, collaboration and a sense of humor are the bases for any good therapy. Of course, I’m also a staunch believer in evidenced-based psychology and have worked diligently to become fluent in many forms of cognitive behavior therapy (CBT). If you want to know more, I geek out in “The Academic Stuff” below. But in short, my approach has rigorous research at its core, and I continually seek out training opportunities so that I can be on the front lines of the most modern and effective treatments. My goal is to help you get the changes you want out of your life, as quickly as possible.

I work with adolescent and adult clients who have OCD and/or anxiety disorders across the spectrum. I also work with clients undergoing a difficult life transition or stressful circumstance. Helping clients identify core values is key. It guides the therapy and helps you get from where you are now to where you want to be.

I do work with children who have OCD and anxiety disorders, and this work is done hand-in-hand with parents. Therapy with children is a team effort, so parents will meet with me in separate sessions to discuss how to coach their children through treatment. My goal is to have both children and parents leave therapy with a new set of coping skills.

I practice in Manhattan and Greenwich, as well as via telehealth.

The Academic Stuff
My love of psychology began at Duke University. When I took Abnormal Psych I was convinced I had all of the disorders. Luckily our professor warned us that would happen. After I graduated I worked in book publishing (see “avid reader” above), where I got to work with authors like Malcolm Gladwell, James Patterson, and Deepak Chopra. But loving that job as much as I did, I still knew psychology was my passion. I received my doctoral degree from Boston University, where I was trained in the nationally-renowned Center for Anxiety and Related Disorders. I interned at the Bellevue Hospital/NYU Child Study Center, and stayed at NYU for my postdoctoral training. This is where I was lucky to meet my work wife, the unbeatable Dr. Sameena Groves.

I have been on faculty at NYU Medical Center and Weill Cornell Medical Center and often consult for Real Simple and Parent Magazine.

I have received advanced training in acceptance and commitment therapy (ACT), exposure and response prevention (ERP), dialectical behavior therapy (DBT), mindfulness-based CBT, and Supporting Parenting for Anxious Childhood Emotions (SPACE).

Outside the Office
As well as being a psychologist, I am the mother of two children and a bulldog. I’m an avid reader and a not-avid runner. When I’m not in therapy sessions, I spend much of my time trying to get my children off screens. I love taking writing classes, going on family walks with our dog, and working in my community to increase mental health awareness. Those skills I’m teaching in session? You’ll find me using the very same because life for everyone is messy and wonderful.

Why Do Children Lie, Cheat and Steal?

Inside the Office
I enjoy working with a diverse array of adolescents (13+) and adults. My clients often seek therapy to address some combination of low or anxious mood, sleep disturbance, relationship struggles, distraction, unwanted habit loops, distressing thinking, parenting roadblocks, performance fears, and/or impairment in their ability to function in the areas of life that matter most to them.

My approach to therapy is grounded in the years of training I received in dialectical behavior therapy (DBT) and acceptance and commitment therapy (ACT). I help clients identify their strengths and values, as well as their areas of desired change; together we experiment with empirically-supported skills and practices to build a richer life.

Often treatment includes making changes to sleep, movement, food, and other patterns of consumption, as we know that mental health is not just in our heads. Our lifestyles move us closer to – or pull us further away from – our vision of wellbeing.

The throughline in my approach is skills, teamwork, experimentation, and humor; I laugh often with my clients at some of the absurdities of having a human brain and body. I help my clients become more aware of themselves, learn powerful tools for change, and commit to whole body mental health.

I currently see clients via telehealth and in my Bronxville, New York office. I periodically touch base with my New York City clients in our midtown office.

The Academic Stuff
I received my doctoral degree from Fairleigh Dickinson University and completed my clinical internship at Montefiore Medical Center, where I trained in dialectical behavior therapy (DBT) with Dr. Alec Miller (one of the co-developers of DBT for adolescents). I was able to continue my DBT and CBT training in a postdoctoral fellowship at the NYU Child Study Center (where I happened to share an office wall with Dr. Trosper Olivo!). Since that time, I’ve pursued ongoing training in ACT and enjoy taking the best of what these evidence-based approaches offer clients.

Prior to my graduate studies, I graduated from Yale University and completed a post-baccalaureate program in psychology at Columbia University. More recently I have undergone training in motivational interviewing, health coaching and nutritional psychiatry.

Throughout my career I’ve participated in various conferences and workshops to keep my knowledge current and my connections to colleagues strong; I have been part of a peer supervision group for the past 8 years. I recently began writing a newsletter for clients and colleagues to share relevant wisdom that I come across, and enjoy reading what experts in my field contribute to our knowledge base each year.

Outside the Office
When I’m not in psychologist mode, I’m often caring for my household which includes my husband, two children, a French Bulldog and some very limp plants, last I checked. I’m an excellent starter of books and finisher of smoothies. I love walking briskly on trails, perusing farmers’ markets, listening to podcasts, and exploring different parts of the world. I, like everyone, am a wonderful work in progress.

Inside the Office
I am currently a postdoctoral fellow building my private practice in Rye with guidance from Drs. Trosper Olivo and Groves. I’ve completed my Psy.D. in clinical psychology and will obtain licensure in New York in 2022. I work with children (age 8+), adolescents and adults. My approach to therapy combines building strong relationships with clients while using evidence-based practices in Cognitive Behavioral Therapy (CBT). This blend has allowed me to provide personalized treatment to a broad range of people. I treat a range of anxiety disorders, OCD, and depressive disorders. I also do parenting work with families of children with anxiety and behavioral challenges.

I currently practice in our Rye Brook office, and via telehealth.

The Academic Stuff
From the time I was a child, I knew I wanted to pursue a career in helping people. After graduating from The University at Albany with a major in Psychology, I earned my Master’s Degree in School Psychology at CUNY Queens College. I worked as a school psychologist in Westport, Connecticut, where I conducted comprehensive evaluations for students being considered for special education and gifted education programs. In addition to assessment, I provided individualized and group counseling to school-aged children. I created groups for children with Autism Spectrum Disorder (ASD), children of divorced parents, and groups focusing on leadership/self-esteem/conflict resolution.

While I truly enjoyed my work in the schools, I wanted to expand my knowledge and experience. I continued my education at Fairleigh Dickinson University, where I earned my Doctorate. This opened the doors to my work as an adjunct professor at Long Island University (LIU) and now as a private practice clinician.

I have received specialized training in cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and Supporting Parenting for Anxious Childhood Emotions (SPACE). 

Outside the Office
When not treating clients, I am usually spending time with my husband, two school-aged children and beloved Goldendoodle (who is often accused of being my favorite). I am very active in our community, where I serve on the Blind Brook PTA Executive board, as well as the Congregation Emanu-El of Westchester Board of Trustees. I am a lover of music and fitness, and can be found Peloton-ing to pop hits, or following the Dave Matthews Band around the country, depending on the season. I also love dining out and spending time with friends.
