A phone line that answers around the clock is the first thing this firm puts in front of you, and that single detail tells you a lot about who the practice is built for: someone who just got a call from a federal agent, or whose family member did, and cannot wait until Monday. Federal Criminal Defense, the practice of attorney Karren Kenney, leans hard into that urgency. The number sits at the top of nearly every page, the consultation is free and confidential, and the pitch is that a lawyer picks up whenever the worst news lands.
What separates Federal Criminal Defense from a general criminal shop is where it plants its flag. The federal side is the headline, and it is treated as a distinct discipline rather than a bolt-on to state work.
Where the federal focus shows up
Read past the homepage and the federal practice fills out with real categories. White-collar matters, conspiracy charges, wire fraud, tax fraud, drug crimes, gun crimes, cyber crimes, and cryptocurrency fraud each get their own treatment. Crypto prosecutions are a newer, messier corner of federal enforcement, and naming it directly signals a practice that tracks where the Department of Justice is putting its resources rather than one working off a stock list from a decade ago.
Federal Criminal Defense also builds a page specifically around the phrase California federal investigation lawyer, aimed at the pre-indictment moment when someone learns they are a target but has not been charged. I find that a smart thing to foreground, because the window before charges are filed is often where a defense lawyer does the most good, and most people do not know to call one that early.
Getting in front of a grand jury referral, or heading off an indictment altogether, is quiet work that rarely makes the highlight reel, yet it can change the whole shape of a case.
Federal Criminal Defense also runs blog-style pieces on federal procedure. One walks through staying silent when federal agents come knocking, which is exactly the kind of plain, useful writing a worried reader searches for at midnight. It reads as genuinely instructive, and it stakes out a point of view instead of reciting a definition. That is more effort than a lot of law-firm sites bother with.
The state cases it still takes
Federal Criminal Defense does not stop at federal court. The state roster is broad: assault, domestic violence, battery, DUI, drug possession, burglary, kidnapping, juvenile cases, and expungement. That range keeps the practice grounded in the day-to-day of a local defense bar while the federal work carries the specialist branding. It also means Federal Criminal Defense can follow a client who starts with a state charge and ends up drawing federal attention, which happens more than people expect in drug and fraud matters.
Expungement is a quieter offering worth flagging. It serves people on the other end of a case, trying to clear a record that follows them into job applications and housing. Its presence rounds out what Federal Criminal Defense covers, from a first arrest through the cleanup years later.
The reach it claims across states
Three offices anchor Federal Criminal Defense, in Costa Mesa and San Diego in California, and one in Houston, Texas. Federal Criminal Defense describes representing clients in federal investigations nationwide, which is plausible for federal work since those cases run in a national court system under one set of rules, so a lawyer admitted federally can travel into districts well beyond a home state.
Still, the Texas office alongside two in Southern California is a concrete footprint, not a vague promise of national coverage. Setting up in more than one market is harder and more expensive than simply claiming to serve everywhere, and the addresses back the claim with something a map can find.
Weighing the contact record against the reviews
Contact is where Federal Criminal Defense is strongest on the credibility front. The phone number, 855-505-5588, is displayed prominently and consistently. Three physical addresses are listed outright, and a contact form sits at a clean, findable URL. There is no public email posted, which is ordinary for a law office fielding sensitive inquiries; the form and the phone line cover the same ground.
Outside reviews are harder to pin down, and it is worth saying so plainly. A Yelp listing exists for Kenney Legal Defense at the Costa Mesa address, complete with phone and hours, but the search turned up no visible star rating or review count attached to it. The firm's own site hosts a Client Reviews page pointing to positive Google feedback. That is self-published praise, not an independent tally, and no numeric rating from Google, Trustpilot, or the Better Business Bureau turned up to back it.
The two halves of the picture pull in different directions. Real offices, a staffed phone line, and a working contact route are easy to confirm on their own. Who has actually hired this firm and how the case went is mostly Federal Criminal Defense talking about itself, with little independent voice weighing in from the outside.
None of that undercuts what the practice puts on the table. Federal Criminal Defense presents a coherent, narrowly aimed operation: a lawyer who takes federal exposure seriously, writes usefully about it, staffs a line at all hours, and backs it with addresses that check out. What it has not built yet is a visible trail of outside ratings, and that gap sits alongside everything else here without canceling it out.
The federal focus is specific and current, the crypto and pre-indictment pages especially, and the free consultation costs nothing to test. What Federal Criminal Defense cannot write for itself is a stack of ratings from people who were not paying the bill, and that piece is still missing.
