“I have worked in the field of recovery for over 23 years… working with Joann Post for the last 11 years has been a wonderful experience – without question Joann has exceeded my expectations time after time.

No matter what time day or night it is, Joann answers her phone. Her level of professionalism and integrity are nothing short of outstanding.”

“I have had the opportunity to work closely with Joann many times over the years. What differentiates PTS from other recovery companion companies is their ability to collaborate, talk through the details of a case, and really be involved with the people they are supervising. They often know about issues going on with a client before we do.

It is difficult to find people who know how to work within the complexities of a treatment team juggling issues unique to high-profile and high net-worth families and individuals. I rest easier knowing Joann is on the case. Her sensitivity to and ability to navigate such issues have been without parallel. I would insist that she is a part of any treatment team I had the opportunity to build from the ground up. She is my A-team, and that’s who she brings to the table with her.”

“After working in the field of addiction and mental health in a residential treatment for a few years, an opportunity presented itself to begin doing companion work with Joann Post. She was an incredible supervisor and example of professionalism and ethical practice. The experience I had under Joann’s supervision was absolutely vital to my own progress in the field of addiction and mental health treatment.

Her caring and consistent involvement in each case is unmatched to any other companion services company I have come across. The training and direction I received as a result of working under Joann continues to resonate in my professional life. Anytime I have an opportunity to work with Joann on a case, I am confident the services and care provided will be top quality and effective.”

Each case is managed professionally and ethically, with the specific needs of the client in mind. Joann and her carefully chosen team are experienced, thoughtful, compassionate, and effective.

As a therapist, collaboration and communication with a client’s other treatment providers is essential for the best possible client experience and outcome. The level of collaboration and communication I’ve experienced with Post Treatment is truly exceptional. It begins with the first call and continues through the completion of the case. Post Treatment Services provides care you can rely on and is always my first choice for my clients.”
