Reaching out to a therapist can be a challenging first step. I am here to help when you are ready. My goal is to be a support in my client’s life and walk alongside them in their therapeutic journey. I have developed a passion for helping teens and adults to develop coping skills to work through and process day to day stressors.

In therapy my goal is to create a safe and welcoming environment, where each client can feel comfortable to explore their thoughts, feelings, and emotions. When working with clients I utilize cognitive-behavioral, person-centered, and mindfulness techniques to help develop a therapeutic style that reflects the client’s needs.

Hello! I am Samantha Vargas. I obtained my bachelor’s degree in psychology at Indiana University and my master’s degree in mental health counseling at Marian University. I work with people of all ages, and I have much experience in working 
with children.

I counsel using a person-centered approach, through which the 
client is the guide of each session in order to obtain goals. I am trained in 
Cognitive Processing Therapy to help clients process traumatic events. I am also
trained in Hormone Replacement Therapy and work with the transgender 
community. I will soon be a Certified Sexual Abuse Youth Clinician (CSAYC) in

I enjoy 
being active and spending time with my dog, Pickels, and he occasionally joins 
me in sessions to help my clients feel more comfortable!

I obtained my bachelor’s degree in psychology and my master’s degree in mental health counseling from Indiana University. I work with clients of all ages and have much experience when it comes to working with children and teens. I also specialize in human development and family services. 

I use a person-centered approach in my counseling and therapy. I believe that it is important that the client is placed at the forefront in goal-setting and treatment planning.  I believe that much good therapeutic work can be performed both in and between appointments.
