Dr. Donald Horowitz has the following 2 specialties
A psychiatrist is a doctor with specific training in the diagnosis and treatment of mental illness.
He or she can not only provide the counseling necessary to both diagnose and treat a patient, but can also prescribe medication when needed. In some cases, a psychiatrist will only provide the medication and the counseling will be provided by another healthcare specialist, like a certified counselor or psychologist.
Like other doctors, psychiatrists employ diagnostic tools like CT scans and MRI in order to observe the structure and function of a patient's brain.
Once a diagnosis is made, these specialists may use behavior or cognitive therapy in order to address the patient's condition, or a multitude of other types of therapy, in conjunction with or in place of medication.
A neurologist is a physician who diagnoses and treats disorders of the nervous system which is comprised of the brain, spinal cord and nerves. These doctors do not perform surgery, but refer patients to neurological surgeons when they determine that surgical intervention is necessary.
Some of the conditions that neurologists diagnose and treat are epilepsy, aneurysms, hydrocephalus, Parkinson's disease, multiple sclerosis, stroke, spinal disc herniation, and spinal disease.
In addition to using diagnostic tests like MRI, CT scans, EEG and EMG, neurologists also employ neurological testing to gauge muscle strength and movement, balance, reflexes, sensation, memory, speech, and other cognitive abilities.

This guy has the WORST professional boundaries I have ever encountered. I scheduled an appointment with him a month in advance, and when I arrived I was told he'd lost his appointment book so didn't know I was coming but if I was willing to wait he'd try and see me. So I waited. And waited. And waited. At one point he asked me if I would mail off a prescription for another patient at a local post office for him, then decided that he should do it himself - so he locked me in his office and said he would meet with me when he got back. He then met with me for 40 minutes, talked mostly about himself and his own issues, and then told me to come back a week later to "finish the appointment" so he could write me a prescription. My appointment was for 1:15pm, and we ended up meeting at 6:20pm - I spent the entire five hours waiting in his office, because he made me think he would get to me soon. I was at the tail end of insurance coverage so needed to see him in order to have a renewed prescription before my insurance ran out, or else I would have left. He also shared inappropriate details about other patients with me (he did not use names, but I shouldn't be hearing ANYTHING about his clients!). He seems to know his stuff about medications, but the man has profoundly unhealthy professional boundaries. I was instructed to call ahead of time for my follow up appointment, and was told that another patient had been severely late for her appointment but he still needed to see her, so could I come later? He asked me to call half an hour later (at the time of my appointment) to see where he was at with her - she still hadn't arrived yet, so he asked me to push my appointment back AGAIN by another hour. We'll see if he's actually ready for me when I show up this time. He may be good with medications, and he is very kind, but he's extremely scattered, profoundly unprofessional, and borders on breaking HIPPA laws on a regular basis. No boundaries whatsoever.
