Mark Carlson, MD
Dr. Carlson is a fellowship-trained, board- certified geriatrician, internist and oncologist with almost 30 years of healthcare experience. He received his medical doctorate from Loma Linda University in California and completed his geriatric medicine fellowship at the University of Hawaii in Honolulu.
Prior to his move into geriatrics, Dr. Carlson spent nearly 20 years of practice in medical oncology, where serious illness had to be managed with the latest in medical technology, compassion and a trusting patient-doctor relationship.
