Dr. James M. Campbell, M.D.

Dr. James M. Campbell, Board Certified in Psychiatry and in Administrative Psychiatry, a Distinguished Life Fellow of the American Psychiatric Association announces his new office in Scottsdale. Dr. Campbell obtained his Degree in Medicine at the University of Santo Tomas, Manila, Philippines. He completed his residency training in Psychiatry and Psychoanalytic training at Westchester Medical Center, Valhalla, New York.

I was born, raised and educated in the Philippines. My grandfather who was with the U.S. Army Engineering Corps was deployed to the Philippines after the Spanish-American War, when Spain ceded the Philippines to the United States. The young soldier married a young Filipina school teacher and had my father, who was their only son.

I came to the United States two years after I graduated from medical school and went to New York for my specialty training in Psychiatry.

My moves from New York to Pennsylvania, then to Arizona have given me a vast knowledge of the richness of the American culture and an intimate knowledge of its people. My experiences in both private practice, and with the Veterans Administration, have given me a very good view of the health care needs of the civilians and the unique needs of veterans. As a Commander of Medical Units of the U.S. Air Force Reserves, I am a witness to the patriotism and the passion to serve one’s country among the many young soldiers under my command.

I have always been involved not only in organized medicine, but also in community service. In organized medicine I held positions of leadership at the local and national level. I had the opportunity to be a speaker on various topics related to mental health both in the United States and abroad. I am involved in humanitarian work to promote the education and welfare of all minorities and refugees. I am a strong advocate in promoting diversity and inclusion and the elimination of discrimination and prejudice among people.

I have 45 years of clinical experience . I keep my knowledge current. With patient’s consent, I am willing to collaborate with and/or refer patients to other medical health providers when necessary. I treat my patients with dignity, respect and compassion. My practice is always conducted with high ethical standards.
