Specialty care for what we treat best.
Every condition we treat is available to Denver patients: in person with Dr. Lanzillo for eating disorders, OCD, anxiety, and the highest-risk presentations, and by telehealth with the specialist who fits for everything else.
How care reaches Denver families.
In Person in Denver
Weekly sessions with Dr. Eliza Lanzillo for adolescents, young adults, and adults: FBT and CBT-E for eating disorders, ERP for OCD and anxiety, and the complex co-occurring presentations where these conditions overlap.
Telehealth Across Colorado
Secure video sessions with any member of our team, on the Front Range or anywhere else in Colorado: OCD and anxiety, eating disorders, defiant behavior, trauma, perinatal mental health, and longstanding patterns, matched to the specialist who fits. The treatments do not change with the format.
In-Home Intensives Across the Denver Metro
Concentrated eating disorder intensives and OCD and anxiety intensives delivered in Denver, Aurora, Lakewood, Boulder, and surrounding communities: supported meals, real-world exposures, and family-based work in the environment where recovery actually has to happen.
Virtual Intensives, Anywhere in Colorado
The same concentrated care by telehealth: several sessions across a week, or an extended session in a single day, billed at each clinician's standard session rate, the same as weekly therapy. Available from any clinician on the team to families anywhere in Colorado and in 40+ PSYPACT states; your clinician stays on the video call through the meal or the exposure.
Family-Based Treatment for Adolescents
For adolescent eating disorders, parents are positioned as the primary agents of recovery. Dr. Lanzillo works within FBT in collaboration with Dr. Zach Appenzeller, and coordinates closely with schools, pediatricians, and psychiatry. Nina Jolly's caregiver mentorship runs alongside, for the day-to-day work at the table.
Parents, Caregivers, and Young Children
SPACE for the parents of anxious children, Parent Management Training for oppositional and defiant behavior, and parent coaching throughout. With children and teens, treatment runs through the family, and we teach the family what to do at home.

Specialty and complex care where it is hardest to find, and a team that covers the rest.
Some clinical presentations are genuinely hard to find specialty care for, even in a metro the size of Denver. Eating disorders and OCD that co-occur and reinforce each other. Anxiety severe enough to reorganize a young person's life. And the highest-risk situations of all: self-harm and active suicidality, where the wrong clinical approach can be dangerous. Dr. Eliza Lanzillo is an eating disorder, OCD, and anxiety specialist trained at the OCD Program at Baylor College of Medicine, with deep fluency in FBT, CBT-E, ERP, and the treatment of complex comorbid presentations. Alongside that, she holds a distinct, advanced specialty in self-harm and suicidality, grounded in evidence-based, suicide-specific care. Her clinical work is informed directly by research she helped author, including suicide-prevention research at the National Institute of Mental Health, where she contributed to the Ask Suicide-Screening Questions (ASQ) toolkit now widely used across medical settings.
That would be reason enough to call. It is not the whole practice. The Evidence-Based Treatment Institute was founded by Drs. Zach and Allie Appenzeller to do one thing well: deliver the treatments the research supports, with fidelity, to families who have often already tried something that did not work. Every clinician on the team is a licensed psychologist with specialty training in eating disorders, OCD, anxiety, or the presentations that travel with them, and every one of them can see you in Colorado by telehealth.
For Denver families, that means the kind of specialty care usually confined to major academic medical centers, without the institutional friction, and without being handed from trainee to trainee. One specialist who carries the whole case, the rest of the team behind them, intensives in your own home or over video when weekly sessions are not enough, and a clinician who answers within one business day. Parents don't cause eating disorders, and families are not the problem to be managed. They are the most powerful resource a recovery has.
If you or someone you love is in immediate danger, please call or text 988 (the Suicide & Crisis Lifeline), go to your nearest emergency room, or dial 911.
In person across the Denver metro and the Front Range.
Patients travel from across the Front Range for in-person care in Denver, in-home intensives come to you, and virtual intensives reach every part of Colorado at each clinician's standard session rate.
