Dr. Ashley L. Bolte
Clinical Psychologist
Ashley Bolte is a behavioral health clinician with a Doctor of Psychology degree in Clinical Psychology and extensive experience supporting children, adolescents, adults, and families. She has worked across a wide range of clinical and behavioral health settings, including Southcentral Foundation, where she has provided care to Alaska Native individuals and families across the lifespan and individuals within the military.
Ashley has experience working with individuals navigating substance use concerns, grief and loss, depression, anxiety, ADHD, trauma, PTSD, family stressors, life transitions, and emotional regulation challenges. Her clinical style is warm, collaborative, solution-focused, and strengths-based. She believes therapy should feel supportive, practical, and empowering, helping clients identify what is working, build confidence, and take manageable steps toward meaningful change.
Ashley enjoys helping clients with both everyday life challenges and deeper emotional healing. This may include helping someone organize their life and routines when ADHD makes daily tasks feel overwhelming, similar to a life-coaching approach, while also creating space to process recent trauma, grief, loss, or painful life experiences. She values meeting clients where they are and tailoring interventions to fit each person’s goals, strengths, and current season of life.
In addition to her clinical work, Ashley brings over 10 years of experience in ABA therapy, behavioral health, developmental disabilities, psychological assessment, autism-related services, and family support. She has worked with children, teens, adults, military families, and individuals from diverse cultural backgrounds. Her background allows her to provide practical, compassionate care that considers the whole person, not just the symptoms they are experiencing.
Ashley is passionate about helping clients feel more capable, hopeful, and supported as they work through life’s challenges.
Clinical Counselor
Dr. Denny Tranel, PsyD, LCSW, PA-C
Therapist & Psychiatric Medication Management
I work with trauma and abuse survivors, with people living with mental illness, with people battling addiction, both the stopping and the staying stopped, and with people carrying more than one of those at once. I've also been in my own recovery for 38 years, so when you walk in, you're not starting a conversation with a stranger. The people who tend to do well with me are the ones looking for a truth teller, a cheerleader, and someone who will walk with them through the muck.
Most people I work with have been numbing for a long time. Numbing isn't just about drugs and alcohol. Some people make their illness a friend and build a life around it. Others hide behind I'm fine. Some numb with substances, some with food, some by staying so busy they never have to sit still. Whatever the shape, the move is the same away from feeling. The work we do together is about stopping the numbing and starting slowly, safely, to learn how to feel again. That's where healing begins.
I also provide psychiatric medication management. When it's the right fit, we'll talk through what you actually need. I've been in the medical field for 40 years. I started as a medic in the United States Air Force and spent 18 months in Iraq as an independent duty paramedic. From there, I earned my Physician Assistant license and have worked in emergency rooms across the country. That experience shapes how I show up with active-duty service members, veterans, first responders, and people in the medical field. We carry things the rest of the world doesn't see, and we need somewhere safe to put them down.
I know what you have witnessed because I have been there. I don't know exactly what it did to you, but I get it. You don't have to translate yourself with me.
I will not ask you to go where I have not gone myself.
