Examples of Problems We Treat

Mental illness can be caused by a combination of genetic, biological, psychological, and environmental factors. At Pinnacle, we treat a wide variety of mental health conditions so that our patients can live happy, healthy lives.


Anxiety can be a normal reaction to stress, but it can also be a debilitating condition that interferes with your quality of life. At Pinnacle Behavioral Healthcare, we offer comprehensive treatment for anxiety disorders that includes medication management, individual therapy, and group therapy.

Attention Deficit Hyperactivity Disorder (ADHD)

ADHD (attention-deficit/hyperactivity disorder) is a real and treatable medical condition. Common characteristics of ADHD include inattentive, impulsive, and hyperactive behaviors. Adults with ADHD can experience one of these symptoms, while others may experience all of them. The symptoms of ADHD can impact everyday life—at home, at work, and socially.


Depression is more than just feeling down or going through a tough time. It’s a real medical condition that affects your mood, thoughts, body, and behavior. Depression can make it hard to function in your everyday life. At Pinnacle Behavioral Healthcare, we offer TMS therapy, intranasal esketamine therapy, customized forms of therapy, and medication management to help you manage your depression.


A phobia is an intense fear of a specific object or situation. Phobias can be crippling and make it hard to live a normal life. If you suffer from a phobia, you may go to great lengths to avoid the thing you are afraid of. At Pinnacle Behavioral Healthcare, we offer comprehensive treatment for phobias to enable you to live a life free from fear.


Bipolar disorder is a real and treatable medical condition that causes extreme mood swings. People with bipolar disorder experience periods of highs (mania) and lows (depression). These periods can last for days, weeks, or even months. Bipolar disorder can be a challenge to live with, but with treatment, it is possible to manage the condition and live a full, productive life.


PTSD (post-traumatic stress disorder) is a real and treatable medical condition that can occur after a traumatic event. PTSD can cause a range of symptoms, including flashbacks, nightmares, anxiety, and depression. If you suffer from PTSD, you may feel like you are in constant danger or that the world is not safe.
