CCH Physicians Receive Board Certification in Emergency Medicine

  • Posted On:

GILLETTE, WY – Deanna Lassegard, MD, and Amanda Opfer, DO, Emergency Medicine specialists at Campbell County Memorial Hospital (CCMH), recently earned board certification from the American Board of Emergency Medicine (ABEM). Dr. Lassegard and Dr. Opfer have both been employed with Campbell County Health since 2018.

Board certification is a voluntary program in which specialists seek to improve their performance and demonstrate a commitment to their profession.

The American Board of Emergency Medicine (ABEM) is one of 24 medical specialty certification boards recognized by the American Board of Medical Specialties. ABEM certifies emergency physicians who meet its educational, professional standing, and examination standards.

There are three steps to achieve Emergency Medicine certification:

  1. applying and credentialing
  2. taking and passing a qualifying examination, and
  3. taking and passing an oral certification examination.

Physicians who successfully complete each of these steps are certified as diplomates of the American Board of Emergency Medicine (ABEM). Certification is for a period of 10 years. To maintain certification beyond the expiration date of the certificate, diplomates must participate in the Emergency Medicine Continuous Certification program (EMCC).

Drs. Lassegard and Opfer join Emergency Department physicians Tyler Dickey, Scott Diering, John Gall, Jonathan Hayden, Stephen Houmes, Mark Kellam, Jon Kerr, Stanley Lawson, and Michael Stolpe who are all board certified in Emergency Medicine.
