He completed his medical degree at the University of California, Davis and went on to complete his residency at New York Medical College. Dr. Katz furthered his education at the White Alanson Psychoanalytic Institute where he continued his training in psychotherapy.  

Dr. Katz’ training in psychodynamic psychotherapy provides the framework for assisting patients who suffer from anxiety, depression, ADHD, and eating disorders such as anorexia nervosa and bulimia. He treats both adolescents and adults.  

One of Dr. Katz’s unique aspects is that he is an expert in psychopharmacology, medical psychiatry and psychotherapy.  Upon meeting a patient who presents with such symptoms, he determines if there is a need for other providers such as dietitians, therapists or medical doctors, to be involved in the treatment plan. If additional providers are needed, he provides referrals and works closely with them using a team based, holistic approach.

Dr. Katz’ primary goal is to achieve symptom relief for his patients. Once symptoms are reduced, he will work with patients to gain more insight into the origins and triggers of the symptoms. His ultimate goal is to help empower patients, avoid relapse, and be able to live their best and fullest lives.
