Code-4 Counseling is located in Lone Tree, CO (South Metro area of Denver), located 18 miles south of Denver’s downtown. Code-4 Counseling provides mental health services to local responder agencies including Douglas County Sheriff’s Office, Arapahoe County Sheriff’s Office, South Metro Fire Rescue, Lone Tree Police Department, as well as a number of additional responder agencies in the Denver Metro region and in rural areas of Colorado. Public transportation is easily accessible within Lone Tree with five Bus & Rail stops; however, much of our work is done on-site for agencies outside of our physical office location; therefore, Code-4 Counseling requires interns to have reliable transportation to travel between sites and to respond immediately to crisis needs should they arise. Keep in mind that some travel may include mountain driving during winter months as Code-4 provides services throughout the state, including many rural counties.
Code-4 was founded by Dr. Sara Metz and her husband, Nick Metz (retired Chief of Police) in September 2017 with a mission of supporting the people and organizations that serve and protect our communities each day.  Direct clinical services include both individual psychological services for sworn and civilian responder personnel (law enforcement, fire, EMS) and their family members (adolescent dependents, spouses/partners), as well as couples counseling.  In addition, we respond to agencies that require assistance following a critical incident (officer-involved shooting, line-of-duty death, or other traumatic event impacting personnel). Code-4 Counseling also offers customized consulting and training mental health services to emergency responders and front-line healthcare professionals across the state of Colorado, and beyond. Training and consulting opportunities may include providing mental health training to personnel, assisting in the completion of an agency wellness program needs assessment, facilitation of psychoeducational webinars for personnel and their families, etc.

Interns placed at Code-4 Counseling are engaged in a variety of services offered by our organization.  The intern’s primary clinical responsibilities are within our counseling and psychological services program. This includes individual and couples counseling, as well as occasional family counseling.  Responsibilities also include phone intakes, safety plan development, and follow-up care for new clients, some of whom may be in crisis.  Interns will also have the opportunity to assist with training if they choose and if they are determined to be both comfortable and skilled at public speaking.  Interns are thoroughly trained and supervised on therapy cases to ensure a high level of competence.  Additional intern responsibility may include crisis response for critical incidents or clients in crisis (these can occur 24/7 so reasonable flexibility is needed), engaging in “ride-along” opportunities with police and fire personnel, fire station and dispatch center visits and wellness checks, facilitating psychoeducational workshops and therapy groups, developing handouts, and assisting with wellness needs assessments (one-on-one interviews, facilitating focus groups, report writing, etc.). 


Code-4 embraces an integrative view with regard to the therapeutic approach to clinical work that frequently incorporates modalities such as Cognitive-Behavioral Therapy, Dialectical Behavioral Therapy, Solution-Focused Therapy, and Cognitive Processing Therapy.  Additionally, Code-4 emphasizes the Gottman Institute when working with couples and offers the opportunity for interns to receive specialized training in this approach if they choose. We have a strong focus on training and providing trauma-informed care given the exposure to trauma the majority of our clients experience. We also encourage alternative therapy treatments such as canine-assisted therapy (Code-4 has two therapy dogs, Elton and Lync, that are often available to both clients and clinicians at the office). 

Interns receive a minimum of two hours of individual supervision each week from their primary supervisor (licensed psychologist) and at least one additional hour of group supervision and case consultation with our entire team.  Interns also participate in weekly didactics and group supervision with the CO-PIC intern cohort. Supplemental weekly individual supervision will be provided by other credentialed professionals and by supervisors of elective focus area experiences, as needed.

Interns will have the opportunity to create and focus on an elective focus during the internship year. Elective focus areas are selected based on intern interest and agency need.  Examples of specialty focus areas may include:


    • Suicide Prevention and Intervention Training
    • Responder Relationship Support Workshops
    • LGBTQ+ Outreach for responder and healthcare personnel
    • Post-trauma Growth initiatives
    • Substance Abuse support groups
    • Crisis Counseling and Emergency Response
    • Responder and Healthcare Wellness Program Needs Assessments
In addition to direct client service, interns will have the opportunity to provide weekly individual clinical supervision to a masters or doctorate level extern.  Interns receive supervision on the provision of supervision and are exposed to didactic discussions that focus on the theories of supervision, reflective supervision, and ethical responsibilities of supervisors.
Interest and experience working with responder and/or front-line healthcare professionals is strongly recommended.  Experience providing trauma-informed care is required.
