Longfellow is helping me think in a different way and I’m very thankful for the help.Trancito Cardona
OneWorld’s experienced behavioral health and social assistance team works alongside our medical clinicians to help patients manage depression, family concerns, anxiety, trauma, risky behaviors, chronic diseases, child and adolescent well-being, ADHD, substance use and abuse, family violence and more complex conditions. Psychiatrists consult with our medical and behavioral health clinicians to ensure that our patients receive the best care through effective assessment and evaluation, diagnosis, medication management and therapeutic services.
OneWorld offers counseling in English and Spanish, and counseling in other languages is available using interpreter services. Social Assistance Workers are available to help patients access resources, address urgent financial issues and work through housing problems, violence, sexual assault and other issues with the goal of promoting self-efficacy in all areas of life that impact health and well-being.

OneWorld Medication-Assisted Treatment (MAT)

OneWorld is proud to offer Medication-Assisted Treatment (MAT) for people who are struggling with substance use disorders. MAT combines behavioral health therapy and medications like Buprenorphine/Suboxone and others to treat substance use disorders. We provide a holistic, individually tailored program designed to address each patient’s individual needs.

Who can receive treatment?

We primarily use MAT to treat people who are addicted to opioids like heroin and prescription pain relievers, but we can also use it to treat people who have alcohol use disorders and smoking addictions.

What does the medication do?

The prescribed medications act to block the euphoric effects of alcohol and opioids, relieve cravings and normalize body functions without the negative effects that accompany the abused drug. We prescribe FDA-approved medications (Buprenorphine/Suboxone and others) based on each patient’s individual needs.

Why is behavioral health part of MAT?

Research shows that combining medication and behavioral health services can successfully treat substance use disorders and help sustain recovery. Different patients may need different types of behavioral health services.

What is the ultimate goal of MAT?

We want each patient using MAT to make a full recovery and to live an empowered, self-directed life.

To make an appointment to discuss MAT, please call (402) 734-4110.

Before using MAT, tell your provider if you are currently taking anxiety medications including derivatives of Benzodiazepine, such as Xanax or valium. Combining these medications with the medications used in MAT can be fatal.

I was drawn to work at OneWorld because of the privilege and honor of working with the underserved. I have dedicated my career to working with the underserved and was formally recognized for this commitment by the faculty of Temple University School of Social Work. I have arrived at a time in my career where I wish to utilize and harness my skillsets to assist as many people as possible before finally signing off.Michael Pellecchia, LiMHp, LMSW, Associate Director of Behavioral Health
