Conditions we Treat


The single most common mental health struggle among Americans, anxiety is characterized by feelings of uneasiness, worry, or tension, in regard to a thought, event, or potential outcome.

While occasional anxiety can be beneficial, persistent, severe, debilitating anxiety should not go untreated.

I loved Onyx to treat my childhood trauma. All the staff were amazing. My personal therapist, Christy M, helped me tremendously with my trauma and is the best therapist I have ever had! I will miss the conversations and the delicious meals made by Chef Ryan. Ryan Sanderson and Elizabeth Hatfield assisted me greatly during my treatment and were a huge reason I was able to stay my entire treatment at Onyx! I truly miss everyone at Onyx! Thank you Onyx for assisting me with everything.

-Olivun P.

I have had a phenomenal experience an Onyx. For better or worse I have been in about a dozen treatment centers, and in every important category Onyx has met or exceeded the bar set by other facilities. One of the few places that was worthwhile and I know I can benefit from regardless if I am in crisis or just want to work on growing. The medical staff is extraordinarily knowledgeable and attentive, the accommodations are comfortable (great beds, smart TV in every room, and tons of outdoor space with a pond and walking trail). The groups are also engaging and interesting. The food is too good to be true, literally steak and seafood once a week and plenty of other options including a salad bar.
-Zachary S.
There aren't enough words to describe how thankful we are with Bunny (Clinical Director) and Ryan (Case Manager) for how caring and professional they were at all times during my daughter's stay at Onyx.

They prepared my daughter greatly to her way yo PHP.

Their staff is also very nice and attentive at all times. The venue is very clean with amazing food.

We highly encourage everyone to try them if you or love ones are in need of great mental and substance abuse help.

Onyx is your place to be!
