What led you to our site means your efforts have produced a reputable, successful diagnostic operation. Our role is supplementary to those achievements.

Established hospitals, imaging networks, private practices and research facilities say Apex helps support their ongoing journey to adapt, pivot and prepare the practice for future uncertainties.

We choose to provide services through physicists who have been in your shoes. Apex resources like Lisa Whitelock, DMP, DABR and Courtney Mitchell, MS, DABR are working with diagnostic teams on a wide range mission-critical activities – from short-term staffing needs to fully outsourced inspections.

If you’re overstaffed and/or your physicists have downtime you likely don’t need us. Alternatively, if you’re seeking to get the most out of the investments you’ve already made, consider Apex for the following types of diagnostic imaging services:


  • X-ray/Radiography
  • Fluoroscopy
  • Mammography
  • Nuclear Medicine
  • Magnetic Resonance Imaging (MRI)
  • PET/CT
  • Ultrasound
  • Computed Tomography (CT)
  • Bone Density

Meet Your Physicists

Lisa Whitelock, DMP, DABR

Diagnostic Medical Physicist

Lisa enjoys the hands-on aspects of medical physics and joined KGHP, an Apex Partner, after completing her Professional Doctorate in Diagnostic Medical Physics at Vanderbilt University in 2014. She has also obtained her diagnostic medical physics certification through the American Board of Radiology. Her career goals include becoming an active committee member of AAPM and mentoring young women in science.

Courtney Mitchell, MS, DABR

Medical Physicist

Joining Radcom, an Apex Partner, early in 2021, Courtney brings a wide breadth of medical physics knowledge to our team. With over five years of consulting experience in the Austin and San Antonio area, Courtney is a welcome addition in the Texas Hill Country. Courtney attained ABR certification in diagnostic medical physics in 2016 after completing a residency program at West Physics. He completed both his MS in medical physics and BS in biomedical engineering at Georgia Tech.
