At Viloria, Oliphant, Oster & Aman L.L.P., You Matter

Unlike a lot of larger firms that follow a “case mill” model of accepting and settling as many cases as possible, we limit our overall caseload, only taking on those that we believe we can win at trial. We do this because it allows us to provide every client with the focused attention and personalized representation they deserve. And, because we are true trial lawyers, we are not willing to accept a lowball settlement; instead, our Reno attorneys will aggressively defend your rights and pursue your best interests, even if that means taking your case to court.

We are proud of our many successes, awards, and recognition we have earned within the legal community. However, at Viloria, Oliphant, Oster & Aman L.L.P., we are most proud of the very real ways in which we have helped individuals throughout Northern Nevada face and overcome immense legal challenges. If you need assistance with a business dispute or commercial litigation matter, are navigating a divorce or child custody battle, or have been injured in an accident or accused of a serious crime, we encourage you to reach out to our firm today to learn how we can help.
