I am an in-network provider for  BCBS PPO, BCBS Choice, Cigna, UnitedHealthcare, Optum insurance.


I am a professional counselor with a Masters in Social Work degree from University of Southern California. I hold a Bachelor's degree in Public Relations and Psychology minor from DePaul University.  


I specialize in working with adults with a wide range of issues such as anxiety, depression, trauma and addiction. My therapeutic approach involves compassion, exploration and insight. I utilize several different treatment modalities such as DBT, CBT, motivational interviewing and mindfulness practices. I believe in living as your best and most authentic self, and I utilize a skills based approach to help clients change undesired behavior patterns.

My goal is to assist clients in coping with their emotions and stress, changing self-destructive behaviors, and also to support them in connecting with others. I offer a safe space where we can work together to find solutions to problems and new ways of thinking.


My journey in the social work field began working with adults with developmental disabilities. Over time I transitioned to working in Residential, PHP and IOP programs throughout Southern California, as an individual and family therapist. I have specialized training as a DBT coach and have extensive experience working as a DBT specialist with adult women who struggle with addiction. I continue to do this work at the residential level of care, virtually, throughout the state of California with Casa Bella Recovery Services. 


In 2020, I transitioned back to living in the midwest and began practicing in Illinois.  I work under the supervision of Holly Harris, LCSW as I pursue my IL clinical license.

I look forward to working with you.
