I believe that at its core, therapy is forming a positive relationship, and then using that relationship to motivate and reinforce healing and change. My greatest strength as a therapist is that I care - I care about the clients in my care, their lives, and their futures.

I have worked with adults, children, and families in a variety of settings and have a strong history of helping children and parents adapt to challenges in their lives.  Since 2013 I have enjoyed helping people overcome anxiety, manage depression, and process the things that have happened in their lives.  

My clinical background and training is in behavioral and cognitive behavioral work with a focus on behavioral and mental health and includes working with families and individuals. I have training and experience in treating depression, anxiety, mood disorders, trauma, behavioral and conduct disorders, attention deficit, general transition and adjustment issues, and family conflicts and dynamics.

For me, therapy is a safe place to truly explore the areas of our lives that impact our daily interactions with ourselves and those around us. Sometimes, when we go somewhere new we need a guide, someone who can help us climb the steep mountains safely and maneuver the hard terrain that can come.  My goal as your therapist is to be that guide and help you navigate through the discoveries made throughout the process. Therapy can be emotionally challenging and can bring about vulnerability that is uncomfortable at times but what I hope to create for you is a place where you know your vulnerability will be protected and safe. 
I am a Master’s graduate with my degree in Clinical Mental Health Counseling and have been working in the mental health field since 2017. The majority of my experience has been with children and adolescents. I have spent the past year working as a Substance Abuse Counselor working with a variety of individuals. I have worked with clients to address anxiety, depression, trauma, and substance abuse. I hope to provide a comfortable place for you so we can go on the journey that is therapy together.

I was inspired to start my path as an LICSW through my personal experiences with others in the helping profession.  They had a profound influence on my life, and it is a privilege to be able to give back to others. 

My goal is to create a space that is non-judgmental, supportive, and collaborative for everyone I work with. I view the therapeutic relationship as a collaboration that  helps you attain your goals; to make the changes that will help you achieve the quality of life you desire. I utilize a person-centered, strengths-based approach with clients, assisting each person in exploring and identifying their own resources and strengths. We then build on those strengths through ongoing personal development so that you are prepared when life challenges arise.

​I have had the pleasure to work in various settings during my career and feel most proficient in assisting clients in developing skills to overcome anxiety, manage depression, working with individuals struggling with substance use/abuse, and helping to navigate other various life stressors. 

I am grateful you have chosen to take this step for yourself and look forward to connecting!

Rick Charity, LCMHC

Licensed to Practice in NH and ME

I am a licensed Clinical Mental Health Counselor who has been working in the mental health field for over a decade. I have a wide range of experiences, from inpatient hospitals and residential treatment through offering in-home child and family services and work in schools, to out-patient counseling. These experiences allow me to bring a broad base of knowledge and skills to my clients, so I can match the supports I offer to your specific situation.


I work from a foundation of person-centered therapy - from the moment we meet, I'll be trying to create a space where you can feel supported, respected, and free from judgement. From that place of unconditional positive regard, I'll support you in growing and changing in the ways that you want to grow and change. I am comfortable using a number of approaches to help my clients, including CBT for some diagnoses, and I offer family and couples counseling in addition to individual therapy. I'm comfortable with treating anxiety disorders, ADHD in older adolescents and adults, as well as supporting clients who are having difficulty adjusting to stressful life circumstances. I particularly enjoy supporting clients dealing with men's health issues. 


In my free time, I enjoy being active outdoors: hiking or ice climbing, gaming, and spending time with my wife and children.
