Inpatient Process

When you call Maryville’s admissions department, you will be connected to an admissions specialist for a brief interview. Based on this interview, the admissions specialist will recommend one of three levels of care: Medically Monitored Detox, Short-term Residential Treatment, or Long-term Residential Treatment.

You will be scheduled to come to Maryville’s Williamstown or Pemberton location to begin the intake process. An admissions specialist will conduct a more comprehensive interview and other standard program procedures. During the intake process, you will receive a handbook outlining what to expect during your stay at Maryville.

Next, as part of our medically-monitored program, you will receive a nursing assessment by a Registered Nurse (RN) from Maryville’s 24-hour onsite nursing department. Within 24-48 hours, you will be seen by a physician for a physical and follow-up to information gathered during the admission process. Maryville’s medical staff will see you as needed during your stay. 

Before you are shown to your room, you’ll have the opportunity to talk to your loved one who brought you to Maryville. Then, a staff member will provide a brief program orientation and you will begin treatment and aftercare planning with your primary counselor within 24 hours of your arrival. Length of stay varies depending on your level of care and individual needs. At discharge, you will be invited to join our Alumni Services program for continued support, social activities, workshops, and mentoring.

Please review the list of items you are permitted to bring with you here. Leave anything else at home, or it will be held by Admissions until your discharge.

Outpatient Process

To begin your treatment at Maryville, you will first complete an intake packet. You may obtain and complete this packet at our Turnersville or Vineland office during regular business hours or click HERE to print the forms in English. Click HERE for Spanish.

Once the intake packet is received, an appointment will be scheduled for your assessment. You will be offered the option of attending your assessment face-to-face or via telehealth. Assessment appointments are available within 24 hours of Maryville receiving your completed intake packet and last approximately one hour.

During assessment, you will be assigned a level of care (Outpatient or Intensive Outpatient/IOP) and a primary counselor. Next, you will be scheduled for group and individual counseling.  

During the first individual session with your primary counselor, you’ll have the opportunity to get to know each other, become oriented to the program, and ask questions. Together, you will begin to formulate a goal-oriented treatment plan. If any mental health needs are identified, you will be connected to our mental health staff for an evaluation.

During subsequent individual sessions, you and your counselor will work on your treatment plan goals, discuss areas of need, and make any necessary adjustments. Treatment averages 2-6 months. Upon goal achievement and treatment completion, you will be invited to become part of our Alumni Services program, which offers ongoing support, social activities, workshops, and mentoring.
