Anxiety and depression therapists and psychiatrists in Lone Tree, CO

My name is Ashley Abbott, and I am a Licensed Clinical Social Worker. I have a diverse background working with children and families who have experienced abuse/neglect, within systems such as the foster care system, the juvenile justice system, inpatient, psychiatric residential treatment facilities, and outpatient settings I have provided direct support services in group homes, court advocacy, and a variety of therapy services such as group, family and individual. These experiences have equipped me with valuable skills in crisis management, de-escalation, family conflict resolution, and supporting individuals facing complex and challenging circumstances. With training in evidenced-based modalities, I can treat anxiety, depressive disorders, life transitions, relationship problems, suicidal ideation, and behavioral challenges. I am also trained to treat trauma and PTSD with EMDR. I am passionate about partnering with clients who are committed to personal growth and willing to actively engage in the therapeutic process. I specialize in working with adolescents, young adults and adults.

I’m a psychiatric nurse practitioner who works from the belief that people are not broken—and that many of the struggles we call “mental illness” make sense when we look at trauma, context, and lived experience. I’m especially attuned to the ways mental health systems, stigma, and labels can unintentionally cause harm, and I aim to practice in a way that feels respectful, collaborative, and deeply human.

My approach is unconventional and trauma-informed, influenced by perspectives like those of Gabor Maté, which emphasize compassion, curiosity, and understanding symptoms as meaningful responses rather than defects. I do not believe in rushing to pathologize the human experience. As Joni Mitchell once reflected about depression, sometimes what we’re feeling is not an illness to be fixed, but a signal—an honest response to pain, loss, or a world that has not been kind.

I have a heart to see breakthrough, healing, and freedom for my clients. I have 20+ years history of working with adolescents and adults with learning differences: neurodivergence, autism, ADHD, dyslexia, and executive functioning deficits. I have extensive experience working with individuals struggling with trauma, abuse, identity, and somatic issues.

I have been in the mental health field for over twelve years. My experience has allowed me to provide therapeutic services focused on those who have experienced trauma, family issues, lack of identity/purpose, and couples/relationship issues.

Emily Biggs-Heisler, Ph.D., is a licensed clinical psychologist and the Clinical Director and Co-Owner of Mountainside Behavioral Health.

She has experience working with children, adolescents, and adults in clinical, research, and testing settings and is intensively trained in brief suicide prevention interventions, cognitive behavioral and trauma-based therapies, and Dialectical Behavior Therapy (DBT).

Dr. Biggs-Heisler provides individual, family, and couples therapy. She teaches DBT skills groups, provides supervision to staff and trainees, and works with clients who are twelve years old and above.

Finding the right therapist can feel overwhelming, especially if you’ve tried therapy before and felt like it didn’t quite click. My approach is active, collaborative, and grounded in the belief that healing happens when we learn new ways of thinking, behaving, and relating to our emotions—not just talking about them.

I am a Licensed Professional Counselor with a trauma-informed lens, specializing in addiction, women’s issues, adolescents, anxiety, and depression. I also have experience supporting parents and individuals impacted by a loved one’s substance use, including navigating boundaries, codependency, burnout, and complicated emotions such as guilt, fear, and grief.

I strive to create a safe, supportive space where clients feel accepted, understood, and gently challenged to grow. Many clients tell me they appreciate that our work goes beyond listening alone—we focus on learning practical skills and applying them to real-life situations.

I also have a background in Christianity and am comfortable integrating faith and spirituality into therapy when desired by the client. I respect each person’s beliefs and values and approach spiritual topics with openness, curiosity, and sensitivity.
