Catherine Peterson, MD, is an endovascular-trained neurosurgeon with advanced expertise in minimally invasive brain and spine procedures. At Inland Neurosurgery Institute, a practice with locations in Pomona and Arcadia, California, Dr. Peterson brings a deep commitment to patient-centered care and innovative neurovascular treatment strategies.

Originally from Moldova, Dr. Peterson immigrated to the U.S. in childhood, where she cultivated a strong work ethic and passion for medicine. She earned her Bachelor of Science in Biology with magna cum laude honors from Purdue and her medical degree from Indiana University School of Medicine. She completed her neurosurgery residency at UC Davis and Detroit Medical Center, followed by a competitive endovascular neurosurgery fellowship at UCLA.

Dr. Peterson specializes in both cranial and spinal neurosurgery, with a particular focus on treating stroke, aneurysms, and complex neurovascular conditions through catheter-based techniques. Her research, including multiple peer-reviewed publications and national presentations, centers on improving outcomes in stroke care and understanding cognitive recovery following brain hemorrhage.
Recognized for her academic excellence and compassionate approach, 

Dr. Peterson received the James E. Boggan Award for Scholarly Excellence twice. She believes in a personalized, respectful approach to neurosurgical care and stays active in the field through membership in organizations like the AANS, CNS, and SNIS.

Outside the operating room, Dr. Peterson enjoys gardening, traveling, and spending time with her family in California’s outdoors.

Richard M. Young, MD, is a highly trained neurosurgeon with the team at Inland Neurosurgery Institute (INI) in Pomona and Arcadia, California. 

Dr. Young was born in Taiwan and came to the United States at an early age. His grandmother always predicted that he would be a doctor. Since the age of 3, he would hold her head when she had a migraine and would say, “When I get older, I will take care of you.”

Excelling in science and math, he went to college as an electrical engineering major at UC San Diego. However, his calling into medicine resulted in him graduating cum laude in biochemistry and cell biology. He continued his journey into medical school at New York Medical College in Valhalla, New York, where he discovered his passion for neurosurgery.

This passion derived from a pivotal case during medical school, where a patient was in a coma from a ruptured brain aneurysm. That same patient recovered weeks later from the brain bleed and surgery. “To have the ability to save a person’s life…that’s what I want to do.”

He completed his neurosurgical training at The George Washington University (GWU) in Washington, DC. During his training, he also spent a year as a research fellow at the National Institute of Health (NIH) – NINDS – Medical Division. After completing his residency at GWU, he came back to the west coast to UCLA for a two-year neurointerventional/neuroendovascular surgery CAST certified fellowship.

Not only has he written many articles, book chapters, poster presentations, and a journal cover for JNS-Spine, but he was also awarded the Bannister Award both for the fastest treatment time of removing a blood clot in the brain during his fellowship at UCLA. 

“Everyone knows how important the brain is, and if damage occurs to the brain, it can be devastating to that person and their family. To me, I do not see a patient but rather another human being that I am trying to help get better, like my grandmother. The reason I joined the group of neurosurgeons at Inland Neurosurgery Institute is that my colleagues share the same vision for helping people.”

During his free time, Dr. Young enjoys spending time with his family, cooking, running, and swimming.
