Dale B. Mortimer, M.D.

Since moving to Clark County in 1991, Dr. Mortimer has had the longest established outpatient psychiatric private practice in the county. He is an internationally published expert on the treatment of ADHD in children, teens, and adults. He is also the Chairman of the Clark County Medical Society Committee for the Promotion of Profit and Joy in Medical Practice (or, CCMSCPPJMP).

In addition to providing psychotherapy, he is also a nationally recognized expert on psychopharmacology. He can efficiently and effectively identify optimal medications and dosing for treating ADHD patients, and quickly identify drug-drug interactions likely to be causing psychiatric symptoms. Half his active patients are 3–18 years old, and the other half are adults. He sees a satisfactory treatment outcome in 90% of his patient population within 12 office visits.
