Every client’s needs are unique. When you schedule your first appointment, the Intake Representative will gather a brief history from you and the reason you are requesting services. . They will assist you with cost and insurance questions, as well as any questions about starting treatment.

Your first session is the initial assessment. Your therapist will discuss what form of treatment, i.e. individual, family therapy, medication management, you would most benefit from and how often the sessions will be scheduled. Typical therapy sessions are scheduled weekly or bi-weekly and last 50 minutes. Duration and frequency of your session is dependent upon your needs. Initial assessments with the psychiatrist will last for one hour. Medication checks are between 15-30 minutes long, and are scheduled on a basis that is consistent with your needs.

Downloadable client forms are available on the Contact Us page. New clients can complete these forms prior to first appointment and should bring the completed forms with them to the appointment.

For all current clients, if you require emergency services outside of our general business hours, our answering service will take your name and phone number and a trained on-call clinician will return your call.

We strive to provide the highest quality of service in a safe and confidential environment. This coordinated clinician team concept offers clients the assurance of receiving a comprehensive, professional care in a comfortable, friendly environment. In addition to our clinician’s professional expertise, they provide a genuine sense of caring, compassionate understanding, and a warm, nurturing attitude.
