Therapy Services offered:


My approach is comprised of three components: first, a relational approach to therapy, where the therapeutic relationship is a partnership and a profound opportunity for healing; second, a practical approach where we work together on specific stress management, resiliency and self care practices, as well as communication skills, parenting and other techniques that are specific and evidence based; and finally, an integrative clinical approach that draws upon my years of training in different but complementary practices - EMDR psychotherapy, multiple approaches that address complex trauma, dissociation and other trauma related challenges; play, sand tray and expressive therapies, cognitive behavioral therapy techniques, and attachment focused therapy with an understanding of interpersonal neurobiology, all complementary, powerful and effective. EMDR psychotherapy is now at the core of my practice because of its effectiveness and ability to help you transform your life.

I use multiple assessments with you to determine your challenges and the best course of action; together we identify concrete ways you’ll know you’re making change. My expertise is in serving people coping with a wide array of trauma and anxiety related problems, including histories of complex trauma and adversity, post traumatic stress disorder and stress related challenges; helping children and their families with mental health challenges in childhood, including anxiety, phobias, behavioral problems, loss; and helping parents manage the unique challenges of parenting children who are neurodivergent and need support. I continually learn emerging skills and knowledge to provide you the best care possible and to satisfy my own quest for knowledge and growth.

My practice offers:

  • Compassionate, holistic assessment that includes evidence based assessments, complete history taking, and a collaborative approach to determine best course of action to help you meet your goals

  • Individual therapy informed by evidence based practices, including EMDR psychotherapy, neuroscience, trauma and adversity research, mindfulness, cognitive behavioral therapy, psychodynamic and family systems therapy, positive psychology, stress reduction and resiliency training, sensory and body regulation strategies, and sand tray and expressive therapies. My areas of expertise working with adults include anxiety, PTSD, complex trauma, panic, problems managing stress, relationship challenges, change of career, and setting career and life goals.

  • Therapy with children and adolescents to help children manage emotions, stress, anxiety and mood challenges, behavior challenges, problems in school, coping with traumatic events, learning challenges, supporting children through family transition and divorce, adoption, grief and loss, and other issues

  • Support for parents, including skills training, counseling and group support

  • Assessments: As a former clinical director, I’ve implemented many varied assessments as part of an evidence based treatment approach, and continue to use assessments to track change and inform our goals. I am highly trained in trauma assessments for all ages, am trained in a “gold standard” assessment for autism called the (ADOS) Autism Diagnostic Observation Schedule, have experience with integrating occupational therapy interventions with sensory needs, and work collaboratively with learning specialists and other therapists in order to provide the most comprehensive understanding possible of your child; I also work closely with school districts to advocate for your child and learn more about their school life if needed.

“Siobhan is fabulous. She is kind, compassionate, wise and experienced. Siobhan has helped me to move forward in my life, especially through some difficult transitions, with new skills and support. She is a knowledgeable and experienced EMDR practitioner and utilizes other resources as well to meet each individual where they are. Siobhan has adapted to the "new normal" of providing counseling, including EMDR, through a secure telehealth app that is extremely easy to use. I highly recommend Siobhan! TY”

Ms. Masterson is perceptive, insightful, and committed to helping her clients grow and supporting their loved ones to that end. We had taken our adolescent daughter to a psychiatrist and two different therapy practices over the course of two years, and our daughter was not properly diagnosed or treated during that time. Ms. Masterson was the first person to really "see" our daughter. She identified the core issues and has used strategies that have been highly effective within a short time. In addition, Ms. Masterson helped us advocate for a targeted 504 plan with the school district. Working with Ms. Masterson has been transformative for our daughter and we wholeheartedly recommend her practice. AP

My sessions with Siobhan have been life changing. She is caring, empathetic, intelligent, patient, skilled in her profession and very kind. I feel so lucky to have found her and I would recommend her to anyone in search of therapy. -SM

Doing EMDR therapy with Siobhan was unequivocally one of the best decisions I've ever been fortunate enough to make. I was prescribed EMDR to recover from symptoms of Functional Neurologic Disorder after a car accident and not only did those symptoms resolve, I was able to get over my oldest hang ups. I'm so glad I didn't have to go the rest of my life without being able to experience the transformation of EMDR. -MF

“Nobody wants to do it - not real change, not soul change, not the painful molecular change required to truly become who you need to be. Nobody ever does real transformation for fun. Nobody ever does it on a dare. You do it only when your back is so far against the wall that you have no choice anymore. ”
