I work to meet clients wherever they are at emotionally and identify their goals so that we can work together to create the best life possible for them. I have experience working with all ages and walks of life, from first responders and caretakers to teenagers and families. I come from a family of helpers and have a deep understanding of how traumatic experiences can destabilize people's well-being. I am here to work as a guide, not a teacher, and believe that all healing is done by the patient. I seek to empower my patients and show them their inner strength that was there all along.

My name is Lydia, I’m a southern transplant living in Colorado 5 years in the making. While I love certain parts of the South, I am passionate about dismantling the restrictive thought patterns brought on by Southern culture.

Many of the solutions we seek are already inside of us. They can be hard to find, but it is possible. Using talk therapy and emotional regulation skills, we’ll work together to identify goals and practices that fit with the life you’re eager to live. I will provide compassionate, steady support as you navigate anxiety, depression, family or relationship challenges, recovery from addiction, and the impacts of ADHD.

I tailor therapy to meet your individual needs and always consider cultural and social context. I also collaborate with other therapists to offer educational and support groups several times a year. Using a combination of physical, emotional, and cognitive tools, we’ll work to improve daily functioning, strengthen coping skills, and increase the joy and ease in your life.

I earned my Master’s in Counseling from Regis University, and I work with adults across a variety of life stages and transitions.
