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.

Dr. Scott Lederhaus became interested in neurosurgery at the age of 20 while he attended the University of California Irvine. During his studies, he managed to connect with Dr. Eldon Foltz who was the chief of neurosurgery at UCI Medical Center and became involved in neurosurgery research while observing several neurosurgical procedures and even managed to perform some experimental surgery on animals himself. From that point on, Scott was hooked on neurosurgery.

Scott finished Med school at Rush Presbyterian Hospital in Chicago followed by a year of general surgical internship at UC Davis. After his general surgical internship at UC Davis, Scott later returned to the University of California Irvine for a 6 year residency. Shortly after his residency Scott joined a practice in Pomona with Dr. Colin McDonald and Dr. David Brown for several years. Just prior to Dr. McDonald retiring he told Scott, “I may not have always had the results of the surgery I performed, but I never did a case that I didn’t feel needed to be done.” Scott felt the same and after hearing those words from Dr. McDonald he chose to live by those words.

Dr. Scott Lederhaus enjoys treating patients in the manner he would want a doctor to treat him. He joined the Association of Medical Ethics formed by Dr. Charles Rosen at UC Irvine Medical Center and later became a Board member for the organization. The Association of Medical Ethics is dedicated to evidenced based medicine and doing what is right for the patient independent of financial gain. He is fortunate to have partners at INI who share the same philosophy. He loves his wife and family.

Dr. Lederhaus is no longer accepting office patients.

Dr. Donald Ye has studied the inner workings of the brain and the nervous system his entire career, seeking better ways to fix problems that afflict the brain and spine. As a student, researcher, and clinician, he has had challenged himself to better understand complex neurological pathways and to provide the best solutions for patients and their families with thoughtful clinical judgment and realistic expectations.

Dr. Ye graduated from the University of California, Berkeley as a double major with Highest Honors in Psychology and High Distinction in Molecular and Cell Biology focusing his research on functional imaging of cognitive pathways. He continued his medical education at the Cleveland Clinic Lerner College of Medicine at Case Western Reserve University where he fostered his interest in neurosurgery and neurosurgical oncology. During this time, as a Howard Hughes Medical Institute Medical Research Scholars Program, he spent time studying rare tumor syndromes and molecular pathways involved in glioblastoma in the Surgical Neurology Branch at the National Institutes of Health in Bethesda, MD.

He completed his neurosurgical residency training at Thomas Jefferson University Hospital in Philadelphia, PA. Under the leadership of neurosurgical pioneer – Dr. Robert Rosenwasser – he learned the importance of being a well-rounded surgeon capable of treating diseases with all of the tools and techniques available and tailoring them to best suit each individual patient. Trained in the breadth of traditional and minimally invasive approaches to the brain and spine, Dr. Ye understands the value of minimizing risk and maximizing recovery to provide the best overall outcome for his patients. 

Dr. Ye joins Inland Neurosurgery Institute to provide the same high-quality, patient-centric neurosurgical care that his colleagues have provided to the community for decades.

In his free time, Dr. Ye enjoys spending time with his wife and daughter, reading, cooking, and traveling.

Dr. Disney believes that patients need an individualized approach to their neurosurgical problems. This includes complex disorders of the spine and brain as well as peripheral nerves. There is no substitute for listening carefully to patients and guiding them to the best approach to their problem. Many problems of the spine and brain give rise to pain or other impediments to quality of life. Dr. Disney utilizes conservative treatments where appropriate to help resolve these problems and return individuals back to active pain free lives. Many patients don’t need surgery but instead find relief with physical therapy, exercise and activity modification. When needed surgery is performed in the least invasive way possible consistent with alleviating the patient’s symptoms and problems.

A frequent recipient of top doctor awards, patient choice awards and most compassionate doctor awards Dr. Disney takes the time to listen carefully to patients concerns and fears. Treatment options are laid out in layman’s terms to allow patients to understand their choices and what is being recommended to them. Most neurosurgical disorders have more than one possible approach to treatment and it is important to empower patients to make the choice that is correct for them.

A graduate of McMaster University in Hamilton Ontario, Dr. Disney initially studied Engineering Physics and later medicine. The critical thinking and problem solving skills of engineering have been applied to neurosurgery with success. A surgical internship at the University of Toronto was followed by Neurosurgical Residency and Fellowship at the University of Alberta where he also obtained a PhD in Experimental Surgery. Dr. Disney has practiced in the same group practice in Southern California since finishing residency. The practice’s name has changed but what has not is a patient centric approach dedicated to achieving the best possible patient outcomes. All the partners of the group share the same philosophy. When not engaged in neurosurgery Dr. Disney enjoys spending time with his family and is an avid skier, cyclist and aviator.

Dr. Disney is no longer accepting office patients.
