About Us
Pinnacle Behavioral Healthcare

The word Pinnacle is generally understood to mean “the highest point or summit.” At Pinnacle Behavioral Healthcare, we aspire to provide our patients with the highest level of mental healthcare available.
Our company was founded by Dr. Olukayode Awosika in July 2011 with the goal of providing psychiatric and psychological services to individuals with mental health conditions. Prior to starting Pinnacle, Dr. Awosika practiced as a staff psychiatrist and chief of mental health services at Hutchinson Area Health Care in Minnesota.
Dr. Awosika’s experience, combined with the experience of our other certified clinical staff members, allows us to provide our patients with a wide range of psychiatric services that are tailored to meet their unique needs.
Our mission is to provide top-notch patient-centered services to individuals with mental health needs in a dignifying and compassionate manner. We are committed to excellence in helping our patients improve the quality of their lives in a timely manner.
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
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
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.
Phobias
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
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
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.
