Why Choose DISC
– Anthony Yeung, MD (Retired)

Founded in Phoenix, AZ in 1998

In 1998, orthopedic specialist in minimally invasive spine surgery, Anthony T. Yeung M.D. (retired), founded the first spine-focused out-patient ambulatory surgical center called Squaw Peak Surgical Facility, in the USA. In 2002, Christopher A. Yeung M.D. joined his father Dr. Anthony Yeung in practice. Justin S. Field M.D. later joined them in practice in 2007 to form Desert Institute for Spine Care (DISC). Today, DISC has five spine fellowship trained, board-certified spine surgeons, with 4 convenient locations serving patients in the greater Phoenix, Scottsdale, Mesa, Chandler, and Glendale, Arizona areas.

Our founder, Dr. Anthony Yeung pioneered, and developed the first true arthroscopic spine surgery instrument system called the Yeung Endoscopic Spine System (YESS). With YESS, he and his partners at DISC further developed and popularized a group of least invasive surgical techniques called endoscopic spine surgery. These endoscopic procedures have revolutionized the future of spine surgery, resulting in better patient outcomes.

DISC Philosophy – The Least Invasive Spine Care

At the heart of DISC is our philosophy for treating spine patients – To utilize the least invasive yet most effective treatments available to restore, revitalize, and rejuvenate our patients’ active lifestyles.

Our comprehensive least invasive spine care and our innovative endoscopic spine surgery experience has differentiated our spine surgeons from their peers nationwide for over two decades. Patients continue to highly recommend our surgeons because their experience at DISC has restored, revitalized and rejuvenated their active lifestyles.

Our 3 Step Process to Least Invasive Spine Care

STEP 1: Getting to Know Your Pain Journey

WE LISTEN CAREFULLY. We ask targeted questions. We want to understand your pain story, how it affects your daily life, and what your desired outcome is. We are here to instill hope and long-term pain relief for your future.

STEP 2: Personalized Pain Mapping (PPM)

Personalized pain mapping is a proprietary DISC method we developed to accurately define the spine condition and pain generator. Sometimes called diagnostic pain management, PPM identifies the pain generator by correlating, patient pain story, image studies, and then applying diagnostic therapeutic injections that relieve or confirms the patient’s pain.

STEP 3: Surgical Pain Management

Today patients in pain are sent to pain management which treats your symptoms with short-term relief injections, or noninvasive procedures. Often times these pain patients have to come back in six to twelve months to have procedures repeated.

DISC has pioneered and developed a new and emerging subspecialty called Surgical Pain Management. Utilizing PPM, we developed a group of new cutting-edge surgical techniques called endoscopic spine surgery.

Surgical pain management diagnoses and treats the root cause or pain generator with least invasive endoscopic spine surgery, resulting in long-term pain relief results. Our endoscopic surgical techniques have proven to provide significant long-term pain relief when compared to traditional pain management procedures.



Since founding Desert Institute for Spine Care in 2007, our surgeons have worked to serve their patients and the needs of the community in which they work. Our surgeons have continually served the greater medical community of Phoenix, AZ, to promote patient outcomes.

In addition, our surgeons have championed many fundraising causes over the years, including: 

  • Fitzs Supper Club – benefiting breast cancer and various local charities
  • We’ve Got Your Back – DISC’s 5k race fundraiser for Spinal Research Foundation
  • Leukemia and Lymphoma Society
