Pacific Neuroscience Institute is proud to offer a Multidisciplinary Voice Clinic — bringing together Dr. Omid Mehdizadeh, MD, and our speech language pathologists in a single same-day visit to evaluate, diagnose, and build a treatment plan for patients with voice and upper airway disorders.

The clinic treats a wide range of conditions including vocal fold lesions, polyps, nodules, cysts, granulomas, vocal cord dysfunction, and chronic cough. The team works extensively with professional voice users — singers, actors, teachers, athletes, and fitness instructors — and brings firsthand experience to the care of each patient.

Treatment options range from voice therapy to in-office procedures and surgery, with plans tailored to each individual's condition and goals.

"The Pacific Neuroscience Institute actually saved my life and I'm forever grateful."

When a routine MRI revealed an 8mm brain aneurysm, Lyn sought answers and found her way to PNI's Pacific Stroke & Neurovascular Center. There, Jason Tarpley, MD, PhD, and Samuel Hou, MD, PhD, evaluated her case together — a standard of care at PNI where patients diagnosed with an aneurysm are seen by both an open surgeon and an endovascular neurosurgeon.

Dr. Hou performed a minimally invasive endovascular procedure, navigating to the aneurysm through the blood vessel and sealing it with platinum coils to prevent rupture. Lynn's recovery was smooth, pain-free, and far easier than she anticipated.

This is the collaborative, patient-centered care that defines the Pacific Stroke & Neurovascular Center at PNI.

In 2012, Manuel Ortiz moved to Los Angeles from Chile as a PhD student with his family. When his twin boys had not begun speaking by 20 months, he sought answers.

Through Venice Family Clinic, the family was referred to Dr. Chester Griffiths, an expert otolaryngologist at Pacific Neuroscience Institute. Dr. Griffiths performed a life-altering procedure that restored the boys' hearing, allowing them to begin speaking.

This is the kind of care that defines our mission at PNI — expert, compassionate, and patient-centered.

Advanced surgical techniques make brain tumor and pituitary disorders treatment more precise and less disruptive.

Keyhole brain surgery is a minimally invasive approach that uses small, targeted openings and endoscopic methods to remove pituitary and select brain tumors. This technique helps preserve healthy tissue, reduce recovery time, and improve outcomes compared to traditional open surgery procedures.

At Pacific Neuroscience Institute, our neurosurgical team integrates these techniques into a comprehensive, patient-centered approach.
