I have worked in the medical field since graduating from Holyoke Community College in 2010 with my Associates and medical assistant degrees. I have worked in both administrative and clinical settings in that time, and have worked as a practice manager since 2017. I am passionate about behavioral health, and am dedicated to the comfort, confidentiality, and overall wellbeing of the people who contact us for assistance.
I strive to make the process easy and transparent, by developing relationships that allow each person to feel comfortable and reaching out with any questions or concerns. From the initial contact, through the paperwork and scheduling process, up until the final report the main goal is to have you feel at ease, and understand all aspects of the assessment or assistance you are seeking. Being able to help get the assistance and answers you need for improving your life is my main focus.

Dr. Nancy Haffey is a founding member of the Haffey Center. The Haffey Center was founded in 2007 by Dr. Haffey and Dr. Mark Haffey with the specific focus of providing high quality, evidence-based assessment and treatment services for people experiencing ADHD. Prior to her work at the Haffey Center, she had been in independent private practice for eight years. Prior to this she had worked as a staff psychologist for almost 20 years at Valley Health Plan and Kaiser Permanente..
During her time as a psychologist with Valley Health Plan and Kaiser Permanente Dr. Haffey became aware of the unmet assessment and treatment needs of children, adolescents and adults with ADHD. Utilizing the work of Dr. Russell Barkley, and other researchers and practitioners in the field of ADHD, she developed and implemented many of the clinical practices that continue to form the foundation for the work of the Haffey Center currently.
Dr. Haffey retired from clinical practice on July 1, 2020. Any referrals for Dr. Nancy Haffey will therefore be directed to one of the five psychologists currently working at the Haffey Center. Any requests for past records or reports from having worked with Dr. Haffey will be handled by the staff at the Haffey Center.

I am a Licensed Psychologist and have been practicing in the Pioneer Valley since 1986. I received my BA at Indiana University and my EdD in Psychology at Boston University. I have provided psychological services in community mental health clinics, an HMO, and currently in private practice. I am a member of both the American Psychological Association and the Massachusetts Psychological Association. I provide individual and family treatment for children, adolescents and adults. I specialize in assessments and treatment for ADHD and treatment of anxiety disorders and depression.
As a psychologist I believe it is important that my assessment and treatment work is grounded in the best available evidence of what is helpful and useful. I also believe that the connection between the therapist and the individual is extremely important. I believe that each individual brings to therapy a great deal of knowledge and understanding of who they are and what they need.
One aspect of my work is to reach an understanding of what each family or individual already knows, to understand where they are experiencing difficulty, and to offer new ways of approaching problems. This process assists each individual or family to move forward toward their goals for change or problem solving.
While there are many psychological approaches that have been found to be helpful, there are a few which I tend to utilize more frequently because of both the scientific evidence that shows their effectiveness as well as my experience with them. One is Cognitive/Behavior Therapy (CBT). CBT often provides a new way for individuals to understand what is the cause of their difficulties as well as to provide tools for addressing those problems. Another approach that I find very helpful is Mindfulness. Mindfulness, in very simplistic terms, is the skill of being able to be present in the current moment. Both scientific research and my experience suggest that this simple concept can be extremely helpful as we go forward in living our lives.
An important part of my work over the years has been focusing on parent/child relationships. I have frequently found that children and their parents can improve both their relationship with each other as well as their individual functioning. This occurs when specific approaches to the relationship are introduced and become part of the pattern of the relationship they have with each other. While there are many aspects to this issue, two that have seemed of critical importance are mutual respect and a commitment to a process of learning.
My work is ultimately based on the principle that no one approach or solution works for everyone. What will eventually be most helpful becomes apparent in a process of mutual collaboration that occurs over time.

I am a Licensed Psychologist who has been practicing in Massachusetts for the past few years. I earned my BA degree at Otterbein College (Ohio) in 2006, and MA and PsyD at the American School of Professional Psychology at Argosy DC in 2014. I have provided psychological services in community mental health clinics, VA hospitals, and in private practice. I am a member of the American Psychological Association.
Psychological evaluation involves an analysis of developmental, cognitive, emotional, and environmental contributions to functioning and performance. The most important part of the evaluation is the personalized recommendations for individuals to achieve their goals. Although I specialize in ADHD assessment, additional services include evaluation of intelligence, personality, emotional abilities, and neuropsychological functioning.
In addition to providing assessment and treatment planning, I am experienced in providing individual therapeutic services where my approach is largely informed by evidence based theories. However, no single method is helpful for everyone so I approach each person with respect to individual needs and goals. I believe that each person is an expert in their own lives, and view my role as collaborative. As a psychologist I share my knowledge of skills and interventions while striving to empower individuals to increase meaningful and positive experiences in their lives by providing compassion, support to promote healing.

I am a Licensed Psychologist who has practiced in the Pioneer Valley area for the past few years. I graduated from New York University with a BA in psychology in 2009, and I earned an MS and PhD in Counseling Psychology at the University of Florida, completing the latter in 2016. I have worked with individuals doing therapy and psychological assessment in a variety of settings, including college counseling centers, inpatient psychiatric units, and outpatient psychiatry clinics. At the Haffey Center, I provide comprehensive psychodiagnostic evaluations for ADHD and learning disabilities as well as therapy for individuals with a variety of presenting concerns.
In conducting both assessment and therapy, I believe in a transparent, collaborative process between myself and my clients.
Psychodiagnostic assessment is a unique tool that allows individuals to understand their processes in a new light and obtain information about their strengths and weaknesses. I see myself as a guide and analyst, bringing my professional experience and abilities to each person’s presenting concerns and questions.
As a therapist, I know that the quality of the therapist-client relationship is the most important foundation of the work, and I aim to create a safe, nonjudgmental environment in which to cultivate such a relationship. I take a person-centered therapeutic approach and consider the many systems (e.g. cultural, familial) within which individuals are functioning. I value social justice and consider it an integral part of my work as a psychologist. Mindfulness-based psychotherapy, Cognitive-Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and emotion-focused therapy (EFT) are some of the evidenced-based treatments I frequently utilize. In general, I treat individuals dealing with depression, anxiety, ADHD, family/relationship issues, grief, self-esteem problems, and other concerns.

I am a Licensed Psychologist at the Haffey Center for Attention and Memory. I earned my B.A. in Neuroscience and Behavior at Vassar College and my Ph.D. in Clinical Psychology at Suffolk University. I have trained and worked in a variety of settings including Albany Medical College, Boston Medical Center, Cambridge Eating Disorders Center, Capital District Psychiatric Center, Massachusetts General Hospital, Newton Public Schools, Suffolk University Counseling Health and Wellness Center, and the Veterans Health Administration. I am pleased to now extend my work to the Haffey Center community.
In conducting an assessment, I prioritize transparent communication to build a trusting relationship, with a focus on developing an understanding of one’s individual strengths and vulnerabilities.
When learning about your presenting concerns, I form hypotheses about what additional areas may have gone unnoticed and should also be explored. As such, you can feel assured that your experience and concerns are valued and that, through the assessment process, together we can discover the types of answers you have been seeking.
I am able to offer assessments in the areas of ADHD, educational concerns and issues and for accommodations on standardized tests such as the SAT, GRE and LSAT.
My passion for reading and synthesizing scientific findings from a variety of psychological literatures consistently updates my approach in offering clients the best care possible. I am an active psychological scientist and publish under my maiden name, Olivia H. Tousignant.
