Terry Hagan M.D.

Hello, I am Dr. Terry Hagan. I have been practicing general outpatient psychiatry for the last 17 years after completing my psychiatry residency at the University of Louisville. Before that and after graduating from U of L Medical School in 1979, I did a neurosurgery residency at U of L and then practiced neurosurgery here in Louisville for 16 years. I am board certified by The American Board of Psychiatry and Neurology.

Over the years, what I seem to do the best and enjoy the most is helping people to strive for their full potential. In the treatment of ADHD, there is an upside to ADHD that people do not normally hear about in the medical treatment of ADHD. At Hagan Health, we believe it is much more important to understand ADHD than it is to medicate it, such that medication is a useful tool in the toolbox should you choose to use it.  But understanding ADHD means having an awareness of the weaknesses in order to compensate for them, while using the strengths of the ADHD brain as one’s ticket to success. People with milder degrees of ADHD are creative, intuitive, intelligent people with great potential. At Hagan Health we have developed a program of managing ADHD with medication, coaching, and sometimes psychotherapy, always with a positive and encouraging approach.


Another specialty we have at Hagan Health is in the area of treatment-resistant depression. We use a combination of medication management and psychotherapy to treat depression, and our NeuroStar TMS device (transcranial magnetic stimulation) gives us the ability to treat difficult depression with a technology that actually works better than medication.  We are really excited to have this option to help people when medication is either not working or when the side effects are moderate to severe. TMS is therefore an area where my background in both neurosurgery and psychiatry come together to help people, and I enjoy being able to do that.
