I have almost 10 years of experience working in the behavioral health field and take a very active approach to therapy focusing on teaching skills and working with you to learn the ways in which your brain may be contributing to your difficulties. Pain and suffering is part of the human experience and it doesn’t have to keep you from living the life you want to live. There are things we can learn and skills we can use to lessen the impact pain and suffering has on our lives allowing us to be more present. I utilize ACT (Acceptance and Commitment Therapy) which is an active therapeutic approach that helps decrease the power that painful thoughts, feelings and memories have over our lives. In our sessions, we will focus on uncovering how painful thoughts and feelings hook you and what you can do to unhook in order to be more present and put your energy into healing rather than dwelling on the negative. I work primarily with adults and work with people experiencing a variety of mental health struggles such as depression, anxiety, ADHD, trauma, Bipolar Disorder, and substance use challenges as well as many other issues.

Sara BaDour

Qualified Mental Health Professional,
Licensed Professional Counselor

B.S., 2016, University of Wisconsin-Eau Claire
M.S., 2021, Capella University

My name is Sara BaDour. I am a Qualified Mental Health Professional and LPC Applicant with a focus on trauma and crisis counseling. I practice from a person-centered approach in which I believe the client is the expert in their own life, creating a collaboration between client and clinician.

Building rapport and a therapeutic relationship is a necessary foundation for any therapy and heightens the efficacy of individualized interventions like CBT, DBT, and trauma-informed care. I also have a background in neuroscience which I integrate into my therapy to provide clients an understanding of how the brain works, relating it back to their presenting problem(s). I worked with clients experiencing a wide variety of issues from depression and anxiety to substance use, trauma, and personality disorders.

No one client is the same, which is why the therapeutic interventions are structured to the client in a collaborative fashion, empowering the client to regain strength in themselves and their lives.

Jennifer Barnes is a psychiatric mental health nurse practitioner (PMHNP) committed to providing holistic, evidence-based care.

Before attending graduate school, Barnes spent the past 20 years working in women’s health and maternity care as both an RN and a board-certified lactation consultant (IBCLC). Several observations over the past many years contributed to her decision to return to graduate school: the rise in mental health disorders, the challenges in finding qualified providers, and the lack of community support. Her background in women’s health has given hera strong foundation in the way hormones interact with mental health.

Jennifer is passionate about collaborating with individuals to help them feel their best and live fulfilling lives. When not working in this role, she loves to read, take walks with her dogs, and spend time with friends and family. She grew up in the Pacific Northwest and enjoys all that the area has to offer.

Ana Cupp

Clinical Social Work Associate

B.S.W., 2018, University of Nevada
M.S.W., 2019, University of Nevada

My name is Ana Cupp. I am a Clinical Social Work Associate with a focus on trauma. I work with clients experiencing a wide variety of issues from depression, anxiety, ADHD, bipolar disorder, personality disorders and trauma. I am influenced by a wide range of modalities in my practice including psychodynamic therapy, interpersonal therapy, existential therapy, gestalt therapy, ACT, DBT, and CBT. 

My approach is trauma informed, person-centered, and strengths based. I incorporate a mind-body connection and somatic experiencing into my sessions. I believe the mind and body are interrelated and one cannot be healed without the other. My goal is to create a safe and trusting therapeutic environment in which the client feels seen, heard and understood. I believe the therapeutic relationship is a collaboration of equal partnership in which the client is the expert in their own lives. I believe the focus of therapy is unique to every client and that the therapeutic relationship is a key tool to helping client’s heal relationally. I also recognize that each individual is distinctly unique and has different needs. I strive to create a collaborative, safe space for clients to face life challenges as they come. As a therapist I work hard to embody the time-honored virtues of sincerity, authenticity, discretion, tact and empathy. I value each individual’s right to self-determination and honor the dignity and worth of every person I meet

Kendra Pittman

Licensed Clinical Social Worker

B.A., 2012, Western Washington University
M.S.W., 2017, Portland State University

I am a Licensed Clinical Social Worker who works primarily with youth ages 12-20 and their families. My background includes over a decade of experience working with youth and families in schools in Oregon as well as in Latin America. I honor the client’s life experiences and knowledge gained through culture and upbringing. My approach to supporting youth and their families is gentle, compassionate, and genuine, yet straightforward. I have a strong foundation in working with youth of all backgrounds and identities who are experiencing depression and anxiety. Some modalities I use include Cognitive Behavioral Therapy, Family Systems Therapy, and Dialectical Behavioral Therapy, however I believe that each person is a complex and unique individual and that there isn’t a “one size fits all” to therapy. Together, we will work to reach the client’s goals by building on the skills already possessed and by using practical interventions to move towards where the client wants to be. We will work together to establish what the client defines as success in their life and how to meet goals for emotional, mental, and physical well-being. I strive to create a comfortable and collaborative environment in order to understand the client and the client’s story. My goal is to offer a space where the client feels safe and empowered. I can facilitate sessions in both English and Spanish.

Sophie Anderson

Qualified Mental Health Professional,
Licensed Professional Counselor Associate

B.A., 2013, Washington State University
M.A., 2022, George Fox University

Hi, there! My name is Sophie Anderson, and I am a nationally certified Qualified Mental Health Professional, and LPC applicant in the state of Oregon. I have a background in forensic mental health and domestic violence work, with a special interest in working with LGBTQIA+ populations, trauma, and women’s emotional wellness. It is my belief that many therapies can be very problem focused, which I disagree with. I believe that people are not their problems and should be seen for their strengths, which is why I prefer to use Solution Focused Brief Therapy (or SFBT)—a type of psychotherapy which focuses on your inner resources, coping skills, and strengths to help you achieve your goals. I primarily work with adults in individual counseling; I will include you on the process of your therapy every step of the way: your diagnosis, my observations, and your treatment goals. When I’m not helping a client, I am at home snuggling with my two cats, Milo and Otis.
