Diagnostic clarity and evidence-based treatment at our Beaver Street office or by secure video, for children, teenagers, and adults.
This practice is based in Flagstaff, and most of what happens here starts with a question that needs a precise answer. A comprehensive evaluation for a child who is falling behind, attention testing for an adult who has compensated for decades, a course of treatment for anxiety or low mood: each one rests on getting the formulation right first. The skills built afterward are meant to be usable on an ordinary weekday, not only in the consulting room.
Practicing locally means you can choose how care reaches you, whether that is a visit to the office, a secure virtual appointment, or a mixture that shifts with the season and your schedule. We have long ties to northern Arizona and work with local families, the university community, and professionals throughout the region, offering everything from individual therapy to forensic and neuropsychological assessment.
This localized Flagstaff service is provided by Psychotherapy.Com℠, the clinical practice of Arizona Behavioral Health Associates, P.C. We are proud to offer expert care not just locally, but to clients across the state.

Six areas account for most of our Flagstaff caseload, with formal evaluation and structured therapy at the heart of the practice.
Referral questions vary widely. Educational testing, neuropsychological assessment, employment screening, and forensic evaluation are all available, and Dr. Lusk has been qualified by the State of Arizona as an expert witness.
Academic pressure, worry, and behavior at home are the usual reasons a young person is brought in. Goals are set at a developmental level that makes sense to the child, with parents supporting them between sessions.
Overlapping profiles are common, and a label chosen too quickly sends support in the wrong direction. Testing is structured to distinguish attention difficulties from autism and from conditions that resemble either.
The work is active. Using Cognitive Behavioral Therapy (CBT), we map how one particular worry operates, then rehearse specific alternatives until avoidance stops being the default response.
Engagement usually disappears before mood does. With teenagers and adults alike, we rebuild structure deliberately and take apart the persistent thoughts that keep a depressive episode running.
Some of the most useful hours involve no child in the room. Parents work on a shared strategy, on holding a limit calmly, and on the dynamics that make one argument recur.
A treatment plan is only as good as the assessment behind it, so a thorough clinical interview or formal testing comes first. Therapy is then built largely on Cognitive Behavioral Therapy (CBT), which asks for your collaboration between appointments as well as during them. Meaningful change generally takes weekly meetings across several months; there is no shortcut on offer. Living here shapes the plan too, from school calendars to long winters to a drive that becomes unreliable in February, and we would rather account for all of that at the start than renegotiate it halfway through.
Care is directed by Della S. Lusk, Ph.D., who provides testing and therapy for school-age children, adolescents, adults, and families, both at the office and by video.

The office is at 710 N Beaver Street. Because we practice in town, testing sessions and standard therapy hours can both be held face to face, which matters for the parts of an evaluation that call for a quiet, controlled room with a clinician in it.
Secure video keeps a course of treatment intact when the roads close or a week gets away from you. Many clients alternate between the two without any change to the plan itself, coming in when it suits them and logging in when it does not.
Students, faculty, and staff at Northern Arizona University (NAU) and Coconino Community College have used this practice for years. An independent evaluation, carried out outside the institution, is often what a disability office needs before accommodations can be arranged.
Our clients live in Flagstaff and travel in from Sedona and Williams and from smaller communities throughout Coconino County. The Beaver Street office suits some of them; for others, a virtual hour is simply the practical choice.
We are at 710 N Beaver Street, BLDG 4, in the Flagstaff Doctors’ Village, about five blocks south of Flagstaff Medical Center. The office has a large, dedicated parking lot, entered from Leroux Street, and there is on-street parking on Beaver and Sullivan Streets. Parking and facilities are wheelchair accessible, and bicycle racks stand directly across from the main entrance.
By bus, we are across the street from Stop 30 (Stop Code 68) on Mountain Line’s Blue Route (Route 2); the agency’s live route map shows the next arrival.
Inside, the suite has separate entry and exit doors, so arriving and departing clients do not pass one another in a waiting room. It is a small piece of the building’s design that does a lot for privacy and confidentiality.
Yes, for children, teenagers, and adults. A comprehensive evaluation gives you a diagnosis you can rely on, along with a written report in the form schools, universities, and employers are accustomed to receiving when accommodations are being reviewed.
It is. Therapy and testing both take place at our Flagstaff office, and several standardized instruments can only be administered properly in person. Your clinician will tell you which parts of a plan genuinely need a room.
Methods and language are adjusted to your child's age and stage, and sessions stay short enough to be useful rather than exhausting. We also speak with parents regularly, so that a skill practiced in session gets reinforced at home during the week.
Dr. Lusk speaks English and Spanish, so a clinical interview, an ongoing course of therapy, or a feedback meeting after testing can be held in whichever language your family finds easier. Mention your preference when you telephone and intake will schedule accordingly.
Our rates are sent in a fee agreement when you schedule an appointment. We can also take whatever out-of-network questions you have. Telephone (928) 774-7997 and our staff will cover the particulars, which means the topic never has to be raised once you are in session.
Call the Flagstaff office when you are ready to arrange therapy or an evaluation. We will talk briefly about what prompted the call, send the fee agreement in advance, and offer appointment times at the office or by video.
Call (928) 774-7997We accept all major credit and debit cards, and we gladly accept HSA, FSA, and HRA cards so you can use pre-tax dollars toward your care. Our practice generally operates out-of-network. This allows us to protect your privacy, keep care highly personalized, and avoid insurance-mandated session limits.
