Thorough, Kind, and Exceptionally Effective

We worked with Bob Casper during a difficult juvenile matter. Our teen made a poor decision and then compounded it, and we felt overwhelmed. Bob combined sharp legal skill with calm, steady guidance. He spoke directly to our son—clear, respectful, and firm—helping him understand choices, consequences..., and how to move forward. He was thorough, prepared, and proactive at every step, and equally present with our family—returning calls, explaining the process, and never sugarcoating while still offering hope. What stood out most was his character: Bob modeled accountability and kindness, treating our son as a young person capable of growth. Because of Bob, we felt supported and informed, and our son left this experience with a plan and a second chance. We’re deeply grateful and recommend him without reservation.

Forever Grateful to Bob

When my wife and I found our son in very grave legal jeopardy, we consulted with and hired Bob. During this extremely difficult time for our entire family, Bob's pragmatic, thoughtful approach kept us updated, cautiously hopeful, and grounded in the fact that we have someone who genuinely cares abo...ut our son's fate and who is also strategic and skilled at maneuvering through the evolving dynamics of a very complicated case. We were particularly grateful to Bob for remaining accessible and easy to talk to during this entire ordeal, especially under the most direst of developments and dynamics. The outcome of this dark chapter in our family's history exceeded our expectations, and we are forever grateful to Bob. We can't recommend him high enough for anyone looking for legal council.

Speechless

I was referred to Mr. Casper by another attorney. He is incredibly personable, responsive and cleared up my case in no time. I didn’t even have to appear in court and all charges were dropped. Absolutely amazing work, incredible man and would highly recommend. Cannot thank him enough!!

What qualities do you want to see in your legal counsel to ensure a successful outcome for you?

I spoke to Robert Casper in the interview process and found him to be professional wise & patient . Knowledge is power....and Casper has both because of his knowledge & his experience . If I were DA or an asst DA ....there are a lot of lawyers I'd rather go against before I would want... to go against Casper. The guys a gentleman; he's unperturbed .... he doesn't get frantic; he doesn't get edgy ...and he comes highly recommended by his peers… Why? Because his demeanor is professional ; his knowledge substantial ; his communication skills .. smooth, articulate and with an implied invitation for you to agree with his viewpoint...it doesn't matter if he's talking to Charlie Manson , Mary the librarian or a cop on the street.... he blends his message based on who he is communicating with .... he worked with me on Saturday and Sunday and took time away from his family and his daughter to do so.... The guy goes the extra mile ....and he's thorough....and he's pricey ....because you get what you pay for in life and with Casper he's worth it....when you talk to the guy you just know..::0 you just know there are NOT going to be 12 jurors who disagree with this guy .... in my estimation, he's got a quiet tenacity and balls which makes him a formidable opponent and a good guy that I want on my side of the trenches..... if you're looking for a pitbull with brains… And you can afford him, … I highly recommend Robert Caspar.

Wonderful Lawyer

Bob is a real gem. He is kind, patient, a good listener - but most of all, he gets the job done - most often, better than you'd expected. He got my "felony" reduced to being completely dismissed, and for that- I consider him a true miracle worker. The case was many years ago, but he's always availabl...e (as I am a fmr. Client) for minor legal questions, etc. In my humble opinion, Bob Casper is everything you could ever ask for in an attorney. I would recommend him with zero hesitation.
