On Monday March 21, 2022 at 4:00 PM EDT Political leaders and members of the medical community at large will come together at the Regional Medical Center to celebrate the 10th Anniversary of The Dialysis Access Institute (DAI) and founder Dr John Ross. The celebration will acknowledge the seminal work that Dr. Ross and the DAI staff have accomplished to improve the lives of kidney failure patients receiving renal replacement therapy.


The Dialysis Access Institute provides lifesaving procedures for patients that have lost kidney function. DAI is a unique, one-of-a-kind facility designed to promote excellent patient care with the best possible outcome. Also, the Dialysis Access Institute provides educational programs and training in dialysis access for physicians, nurses and technologist from across the globe.

What is “Dialysis Access”

Patients with kidney failure will require removal of the metabolic waste products from their body by a process known as Dialysis. Specifically, with hemodialysis, the connection of the dialysis machine (artificial kidney) to the patient requires communication with the patient’s vascular circulation. This communication is referred to as the patient’s “ACCESS.” Alternatively, kidney function may be replaced by introducing and removing fluid into the patient’s abdominal cavity (Peritoneal Dialysis). This type of dialysis requires a different route of access, surgically or percutaneously created. These connections can be accomplished with multiple types of surgical and noninvasive procedures. Once established, the access needs to be maintained. This can involve open surgical procedures or minimally invasive procedures referred to as Percutaneous Procedures. This is the unique and important focus of the DAI.

Description of the Dialysis Access Institute

The Institute was established in 2011 by one of the foremost pioneer and internationally known vascular access specialist John Ross, MD. Located in rural Orangeburg, SC, The DAI is a hidden jewel where a group of dedicated multispecialty physicians are committed, exclusively to the care of patients receiving renal replacement therapy. Possibly not familiar to healthcare providers and patients outside of the dialysis community, The Institute has developed a national and international reputation for work in the area of vascular access. The institute is open 5 days a week and on call 24 hours a day and attempts to obtain excellent patient care in a very timely fashion. The majority of the procedures are performed on an outpatient basis. The advantage of The Institute to patients: Patients receive a range of access services in one visit resulting in less travel, less radiation exposure, less anesthesia than traditional models of multiple providers and appointments.

History of The Dialysis Access Institute (DAI) and Its Importance In the Regional, National and International Medical Community

What makes The DAI a unique facility in addition to excellent clinical care is the role it plays in education of physicians and development of cutting-edge medical devices and procedures. Doctors from the U.S. and foreign countries have all spent time at the DAI in Orangeburg, SC. Here they learn and practice cutting edge procedures and observe and use state of the art medical devices. Physicians working at the DAI are regularly invited speakers at national and international medical meetings. The high volume of patients with various access issues has established the DAI as an acknowledged Center of Excellence in the worldwide dialysis access community.

DAI Founder & Director

John Ross, MD, is internationally renowned for developing outpatient surgical procedures and techniques which provide access to the bloodstream for patients on dialysis. He is the Founder of the Dialysis Access Institute at the Regional Medical Center in Orangeburg, South Carolina. He completed his medical training at the University of South Carolina, School of Medicine and has been a board-certified surgeon for more than 30 years.

Dr. Ross was a founding member and the first Vice President of the Vascular Access Society of the Americas. Dr. Ross’ personal interests include vascular access for hemodialysis patients and the implementation of a standard, comprehensive access care program encompassing patient, physician, and ancillary staff education.

Dr. Ross’ extensive research focuses on improving the scope of hemodialysis access management with his writings extensively published. He has presented at national and regional conferences including the American Society of Diagnostic and Interventional Nephrology, the American College of Surgeons and the VEITHsymposium™.

Dr. Mark London, Medical Director

In March of 2017, Dr. Mark London joined Dr. John Ross at the Regional Medical Center’s Dialysis Access Institute in Orangeburg, South Carolina. In June of 2020, Dr. London was appointed as the new Medical Director of the Dialysis Access Institute.

Dr. London has a special interest in peritoneal dialysis and adopts the latest laparoscopic and percutaneous techniques for peritoneal dialysis catheter placement. He is involved in both writing research papers and conducting clinical trials.

Born and raised in Australia, Dr. London completed most of his undergraduate studies at Griffith University, on the Gold Coast in Queensland, Australia. He transferred to University of Alaska, Anchorage, where he completed his pre-med studies and went on to graduate from St. Matthews Medical School in the Cayman Islands.

Dr. London completed a General Surgery Residency at the University of Chicago. His training was heavily weighted on Laparoscopic surgery, Transplant Surgery and Dialysis Access. He then went into a rural general surgery practice at a community hospital in Warren, Pennsylvania. His practice included general surgery, specializing in advanced laparoscopic surgeries and dialysis access, both open and endovascular procedures.
