Ryan G. O’Hara, MD

Dr. O’Hara brings his extensive background in vascular embolization and minimally invasive treatments for tumors to Comprehensive Integrate Care Utah (CiC Utah). As an endovascular specialist, he is able to treat a variety of conditions throughout the body, with a special focus on peripheral artery disease and vein conditions. His experience with embolization technology and techniques includes innovative treatments for enlarged prostates and varicocele patients.

He received his medical training at the University of Washington in Seattle followed by training in diagnostic radiology at Sacred Heart Medical Center in Spokane, Washington. Dr. O’Hara continued with fellowship training in Vascular and Interventional Radiology at the University of Pennsylvania where he obtained a certificate of added qualification in vascular and interventional radiology.

At the University of Utah and Huntsman Cancer Center, he helped develop the Integrated Theranostics Center (ITC) with particular focus on the use of lutetium-based Peptide Receptor Radionuclide Therapy (PRRT) for the treatment of metastatic neuroendocrine tumors. Dr. O’Hara is also the Director of Interventional Oncology at the University of Utah and Huntsman Cancer Institute.

When he is not pursuing his passion of helping people live better, healthier lives, Dr. O’Hara enjoys exploring the mountains and deserts of Utah with his wife and two cool kids. He loves to tinker in his electronics/wood shop. This creative and technical experience has served him well with his work at the University of Utah Bioengineering Department, where he has helped develop solutions for a variety of medical and healthcare concerns. Several of the projects have received patents.

CiC Utah is honored to welcome Dr. O’Hara to its medical team.
