Southern California Ophthalmology Expert Witness
Dr. Marc H. Shomer's office in Upland places him within practical reach of every major Southern California venue — Los Angeles, Orange, Riverside, San Bernardino, and San Diego counties — for in-person examinations, depositions, and trial testimony in ophthalmic matters.
A practical advantage for Southern California counsel
When an ophthalmic case requires an in-person examination or live testimony, geography matters. Dr. Shomer practices comprehensive ophthalmology in Upland, in the Inland Empire, roughly equidistant from downtown Los Angeles, Orange County, and Riverside. Claimants can be examined at a working ophthalmology office with full diagnostic equipment — slit-lamp biomicroscopy, dilated funduscopy, automated visual fields, and optical coherence tomography (OCT) — rather than a rented conference room.
Regional coverage
- San Bernardino County — home county; office in Upland
- Los Angeles County — including downtown Los Angeles, the San Gabriel Valley, and Long Beach
- Orange County — Santa Ana, Anaheim, and surrounding venues
- Riverside County — Riverside, Palm Springs, and desert communities
- San Diego and Ventura counties — by arrangement
Workers' compensation matters before WCAB district offices throughout the region can be scheduled as QME or AME evaluations; civil matters proceed as ordinary expert engagements. Record review is not geography-dependent and is available for any venue nationwide.
