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.

Ramin AmirNovin, MD, FAANS, FCNS (“Dr. A”) is an accomplished neurosurgeon and spinal surgeon at Inland Neurosurgery Institute (INI) in Pomona, California. Dr. AmirNovin has wanted to be a neurological surgeon since the age of thirteen. While volunteering at the Scripps Memorial Hospital in La Jolla, California, he witnessed a life-saving craniotomy (brain surgery) on a trauma patient, and this inspired him immensely. He double-majored in chemistry and biochemistry and graduated with the highest distinction of summa cum laude from the University of California, San Diego, where he was part of the Phi Beta Kappa Honor Society.

He continued his education in New York City, where he obtained his medical degree with the highest honors (Alpha Omega Alpha Honor Society and Lucien Rubinstein Award) from New York University Medical School. He completed his general surgery and neurological surgery training at the prestigious Massachusetts General Hospital (MGH). He also completed a two-year fellowship program for specialty training in functional/stereotactic neurosurgery at MGH.

Dr. AmirNovin has written several book chapters, numerous articles for peer-reviewed publications, and performed cutting-edge research on brain tumors, movement disorders, pain syndromes, and epilepsy.

Dr. AmirNovin practiced complex general neurosurgery at MGH before moving back to the West Coast to be near his family in 2007. As a board-certified, fellowship-trained neurosurgeon, he has extensive experience in the treatment of complex spine problems and tumors, brain tumors, cranial-spinal trauma, stroke, movement disorders, complex pain syndromes, Parkinson’s, and peripheral nerve diseases.

Dr. AmirNovin believes that the most important service he provides his patients is a “no-hype, no-gimmick, no-pressure approach to neurosurgery.” This is one of the major reasons he joined Inland Neurosurgery Institute, where the other physicians share a similar approach to neurosurgery. He is highly regarded by his patients and the local physicians for doing the least invasive surgery necessary to restore the patient’s health and functional status. He takes the time to explain the disease process to the patient and explains all of the risks and benefits of their various options for treating them.  Dr. AmirNovin is the Senior Partner at INI.

His patient-centered approach to neurological surgery has gained him numerous clinical recognitions based on patient and colleague reviews. He is rated as a Castle Connolly top doctor for multiple years and is routinely a '5-star' medicare participant.  

In his free time, Dr. AmirNovin enjoys spending time with his family, computer programming, skiing, and dabbling in digital photography.

Board-certified neurosurgeon Ali H. Mesiwala, MD, FAANS, takes a solution-based approach to determine anatomic and functional abnormalities and then treats them with leading-edge technologies and integrative medicine.

At his four offices in Newport Beach, Marina del Rey, and Rancho Cucamonga, California, he focuses on helping all of their patients return to their normal lives, getting back into motion as quickly as possible.

The team treats a vast array of neurological conditions. After intensive neurological exams and diagnostic testing, they recommend the best nonsurgical treatments for each person's unique health care needs. They recommend surgery when symptoms are severe or persist despite conservative care.

Patients seek Dr. Mesiwala for his expertise in brain and spine surgery, as well as peripheral nerve surgery and artificial disc replacement surgery. 

He's an expert in complex brain and skull base surgeries, and he has the most experience in artificial disc replacements on the West Coast, including multi-level operations and all types of spinal decompressions.

Dr. Mesiwala is a leader in the field of minimally invasive sacroiliac (SI) joint surgery and has performed endoscopic cranial and spinal surgery since 2004. No matter where pain originates, patients get relief after he performs neuromodulation surgery.

After earning a Bachelor of Science in biomedical engineering and electrical engineering from Johns Hopkins University in Baltimore, Maryland, Dr. Mesiwala received his Doctor of Medicine from the University of California, San Francisco. 

Then he finished his neurological surgery residency at the University of Washington in Seattle, Washington.

He completed his skull base and cerebrovascular fellowships at the University of Washington, International Neuroscience Institute in Hannover, Germany, and the University of Pittsburgh in Pittsburgh, Pennsylvania.

As a respected researcher specializing in the development of novel technologies and minimally invasive techniques for brain and spine surgery, Dr. Mesiwala holds multiple patents for medical devices used in spinal surgery. 

In addition to his private practice, Dr. Mesiwala is the faculty surgeon for various artificial disc operations and spinal fusion operations with innovative techniques. He's a fellow of the American Association of Neurological Surgeons (FAANS).
