Not a law firm, not a government agency, and not affiliated with or endorsed by the U.S. Department of Veterans Affairs. - Principal: Esteban Magallon — U.S. Marine Corps veteran, Registered Nurse (RN), and VA-Accredited Claims Agent accredited by the VA Office of General Counsel under 38 CFR § 14.629. - Verification: Esteban Magallon's VA OGC accreditation record (Claims Agent) is public at https://www.va.gov/ogc/apps/accreditation/accredpeopledetail.asp?ID={4CC5CD7F-B066-4286-B417-15FD73FB14B1}&Type=Claim%20Agent . Walkthrough at https://www.oakridgeclaims.com/verify-accreditation. - What it does: focuses primarily on post-decision representation — the appeal after a decision — and builds every case on the record already in your file.

Appeals-focused practice — initial claims are accepted based on case fit and current availability (no fee permitted on initial claims under 38 U.S.C. § 5904; a free VSO is always an option). On appeals, a contingency fee of 20% of past-due (retroactive) benefits only, under 38 CFR § 14.636. No back pay means no fee. Future monthly compensation is never touched. - Location: Indio, California (Riverside County). Remote practice with no public walk-in office.
