Trusted Defense For Complex Criminal Cases Sentencing Mitigation

Orange County sentencing Mitigation

Most Federal Cases End at Sentencing. That's Where I Do My Most Important Work.

More than 90% of federal defendants will never go to trial. They will face a sentencing hearing. And what happens at that hearing — what the judge reads, what the prosecutor recommends, what the probation officer puts in the presentence report — is the result of work that either happened or didn't happen long before you walked into that courtroom.

I start that work on day one.

What Sentencing Mitigation Actually Means

Most criminal defense attorneys fight the charges. That's their job, and it's an important one. But in the federal system, where prosecutors win approximately 90% of the cases that go to trial, the most consequential work often happens after a plea and in many cases, long before then. In the months between that plea and the day a judge decides what your life is going to look like for the next several years, the work we do is critical.

Sentencing mitigation means building the fullest possible picture of who you are as a human being — not just what you're charged with — and presenting that picture to every person who has influence over your outcome: the prosecutor, the probation officer, and ultimately the judge.

Done well, it changes sentences. Done early, it changes them dramatically.

What I Do That Most Attorneys Don’t

Federal sentencing is a specific skill set. The Federal Sentencing Guidelines are a starting point, not a ceiling. Federal judges have real discretion, and they use it — if they have a reason to.

My job is to give them that reason.

That means understanding what federal judges actually look for when they read a sentencing memorandum. It means knowing how to present your personal history, your family circumstances, your medical or psychological background, your professional record, your community ties — not as a list of bullet points, but as a coherent narrative that helps a judge understand how you got here and why the guidelines don't tell the whole story.

It also means doing the work before the sentencing hearing. Long before.

The Timeline — Why Early Matters

When I take a case, I'm already thinking about sentencing. Here's why.

The presentence report — the PSR or PSI — is one of the most important documents in your case. It's prepared by the probation office and it influences not just your sentence, but your designation to a facility, your eligibility for programs, and your experience if you serve time. A probation officer who understands your story and sees your mitigation materials early is in a very different position than one who doesn't.

Same with the prosecutor. When an Assistant U.S. Attorney understands who you are as a person — before the PSR is written, before the sentencing hearing is scheduled — the government's recommendation at sentencing is more likely to reflect that understanding. And when the government and probation are both recommending leniency, federal judges take notice.

The earlier this work begins, the more it can accomplish.

What the Work Looks Like

Every case is different. But the mitigation work typically includes:

Developing your personal narrative. This is the foundation of everything. I spend real time understanding your history — your family, your upbringing, the experiences that shaped you, the circumstances that led to this moment. That story gets told in the sentencing memorandum, in letters from people who know you, and in your own words to the judge.

Gathering documentation. Medical records, psychological evaluations, employment history, community involvement, letters from family members, friends, employers, clergy, and community leaders. The goal is to give the court a three-dimensional picture of a human being, not a defendant.

Working with the prosecutor early. In appropriate cases, I present mitigation materials to the AUSA before the PSR is written — sometimes before charges are even filed. Prosecutorial discretion is real, although it does go through several levels for approval. But the important thing is that it can be influenced. I had one client facing a change of espionage, who wasn’t charged at all. Another who had a 22 million dollar medicare fraud case dismissed by the U.S. Attorney’s Office after providing extensive mitigation information over a long period of time.

Preparing the sentencing memorandum: This is the written argument to the judge. It is arguably the most important part of your federal case. It addresses the offense, your history and characteristics, the applicable guidelines, and the reasons why a sentence below those guidelines is appropriate. The great thing about federal judges is that they do read everything very carefully. This is why I spend a great deal of time preparing your sentencing memorandum which is based on all the mitigation work we do throughout the course of your case.

Preparing you for the sentencing hearing: You will have the opportunity to speak directly to the judge at the sentencing hearing. This is called Allocution. What you say to the judge and how you say it matters. I have heard judges say that this is the only thing that can change their minds once they take the bench at a sentencing hearing. I prepare every client for that moment. It is your moment!

When prison is a real possibility, I also help you understand the federal prison system — how designations work, what programs are available, how good time credit and the First Step Act apply to your situation — so you are positioned for the best possible experience and the earliest possible release.

Step 1 of 6

What type of federal offense are you facing?

Select the category that best describes the primary charge. This determines which Chapter 2 guideline applies.

Fraud, theft, embezzlement, or financial crime

Wire fraud, mail fraud, bank fraud, tax fraud, embezzlement, identity theft, money laundering — §2B1.1

Securities fraud or insider trading

§10(b) violations, insider trading, investment adviser fraud — §2B1.4 / §2B1.1

Drug trafficking or distribution

Controlled substance distribution, manufacturing, importation — §2D1.1

Tax evasion or tax fraud

Failure to file, false returns, tax evasion — §2T1.1

Bribery, corruption, or public official offenses

Federal bribery, gratuities, FCPA violations — §2C1.1

Other federal offense

Use the general offense level entry for offenses not listed above

Step 4 of 6

Departures and variances

These are adjustments the judge may make above or below the guideline range based on specific legal grounds or the §3553(a) factors.

Has the government filed — or is the government likely to file — a substantial assistance motion?

A §5K1.1 motion allows the court to depart below the guideline range (and below any mandatory minimum) based on cooperation. The departure is discretionary and highly variable.

No — no cooperation agreement

Yes or likely — cooperation expected

Estimate the likely departure in levels below

Is there a downward variance anticipated based on §3553(a) factors?

A variance is a sentence outside the guideline range based on the judge's consideration of individual circumstances — extraordinary family responsibilities, medical conditions, charitable work, aberrant behavior, etc. This is separate from a departure.

No variance expected — sentencing within range

Downward variance expected

Upward variance (government seeking above-range)

Step 5 of 6

Criminal history

Criminal history points determine your category (I through VI). Answer each question carefully — even old or minor convictions can add points.

Do you have any prior criminal convictions?

No prior convictions

Category I — 0 points

Yes — I have one or more prior convictions

Step 6 of 6

Time served estimator

Once the guideline range is set, these credit programs determine how much of the imposed sentence is actually served in a federal facility.

Sentence start / surrender date (optional)

Days spent in pre-sentence custody (if any)

Days detained before sentencing are credited toward the sentence under 18 U.S.C. §3585(b).

Which credits may apply?

Good Conduct Time (GCT)

54 days per year for sentences over 12 months — 18 U.S.C. §3624(b). Approximately 15% reduction. Can be revoked for disciplinary infractions.

First Step Act earned time credits (FSA)

10–15 days per 30-day period of program participation — 18 U.S.C. §3632(d)(4). Not available for certain offenses or for defendants subject to a final order of deportation.

RDAP — Residential Drug Abuse Program

Up to 12 months off for eligible non-violent offenders with a documented substance use disorder.

Results

The measure of this work is in the outcomes.

I represented Mathew Bowyer — the bookmaker at the center of the Shohei Ohtani gambling scandal — from the day of the FBI, IRS, and Homeland Security raid through sentencing. The government recommended 15 months. The probation office recommended 36 months. The guidelines range was 47 to 56 months.

Judge Holocmb sentenced Matt to a year and a day.

That outcome was the result of years of mitigation work — cooperation, character development, documentation, and a sentencing memorandum that gave the court a complete picture of who Matt Bowyer is as a person.

I had a client who was sentenced to probation in a $50 million immigration fraud case based on mitigation. This woman had suffered greatly in her life and she did everything she possibly could to assist the government from the moment she hired me.

I had a client who was facing a 10 year mandatory minimum sentence in a drug trafficking case after trial. By working with the U.S. Attorney and presenting the court with extensive mitigation, he received a sentence of six months!

If you or someone you love is facing federal charges — whether you've just learned you're under investigation or you've already been charged — the time to start this work is now. Call my office: 949-494-7011

"From the start of my case, she has been there for me."
First of all, I would like to thank Diane for everything she has done for me. From the start of my case, she has been there for me. Only very few people were granted bond and she pulled it off in my case. I know for a fact not too many lawyers could have done that. I am on probation for three years.. while “the others” will not have the chance to raise their children and live their lives. I was headed to prison….I am free.. and for that, I am forever grateful.

"Diane’s work is second to none."
Diane’s work is second to none. I was charged with felony DV, and after working with one firm in Irvine that did absolutely nothing, I did some hard research and found Diane.
