  • Biography



    A Californian native, Dr. Atchison graduated Summa Cum Laude, valedictorian, and with Honors from Pacific Union College in the Napa Valley with a Bachelor of Science degree in Biology. Subsequently, he earned his Medical Doctorate in 1998 from Loma Linda University School of Medicine, where he was inducted into the medical honor society Alpha Omega Alpha. He was intern of the year and subsequent chief resident of the year while completing his General Surgery residency at Loma Linda University, where he also took first place in the first annual laparoscopic skills competition.

    He is board certified by the American Board of Surgery, a Fellow of the American College of Surgeons, member of the American Medical Association, and previous Associate Clinical Professor of Surgery at Loma Linda University. He has received teaching awards from the Loma Linda University School of Medicine and the Kaiser Fontana Family Medicine Residency. He maintains his certification in Advanced Cardiac Life Support and Advanced Trauma Life Support.

    Dr. Atchison has treated a wide variety of surgical patients, especially those with malignant and benign breast disease. He applies his skills with laparoscopy, inguinal and umbilical hernia repair, laparoscopic ventral hernia repair, and post-herniorrhaphy neurolysis. His interest in medical missions has taken him to hospitals in Kenya and Peru, and has taught laparoscopy in India. He was part of the team that taught the very first Advanced Trauma Life Support (ATLS) course in mainland China.

    Area of Expertise

    He greatly enjoys the variety and depth of General Surgery, including laparoscopic cholecystectomy, laparoscopic-assisted colorectal resection, wide local excision of melanoma, sentinal lymph node biopsy, thyroidectomy, excision of benign skin/soft tissue masses such as inclusion cysts and lipomas, and of course major abdominal operations.
