Public Defender vs. Private Attorney: Which Should You Choose in San Mateo County?

August 20, 2026

Summary 

• If you cannot afford a lawyer, the U.S. Constitution guarantees you appointed counsel in a criminal case at no cost or low cost, and appointed defenders are trained criminal specialists, not junior lawyers. 

• The real differences are not talent. They are choice, time, continuity, and availability: you cannot pick or easily change appointed counsel, and heavy caseloads limit time per client. 

• San Mateo County has no public defender’s office. It is the only large California county that instead provides indigent defense through the Private Defender Program, a panel of private criminal defense attorneys administered by the county Bar Association since 1968. 

• You can hire a private attorney at almost any stage, and switching from appointed to private counsel is routine. Courts may deny substitutions made on the eve of trial. 

• The right choice depends on the stakes, the complexity, your finances, and how much attorney access your case needs, not on myths about either side. 

Introduction 

Most articles on this question are written by private lawyers to convince you to hire one. This one is written for a firm run by an attorney who spent years doing court-appointed defense before going private, so it can afford to tell you the truth: appointed counsel is sometimes exactly what you need, private counsel is sometimes clearly worth it, and the deciding factors are specific and knowable. Here they are, including the part almost nobody covers San Mateo County’s system is unlike nearly every other county in California. 

For a straightforward case with modest stakes, appointed counsel is often a sound choice, and paying thousands of dollars may not change the outcome. For cases with high stakes (felonies, strikes, professional licenses, immigration exposure) or cases that turn on early, time-intensive work such as pre-filing advocacy, evidence challenges, and negotiated reductions, private counsel’s main advantages, time and continuity, tend to matter most. The rest of this article explains how to tell which situation yours is. 

How Court-Appointed Defense Works in California 

If you are charged with a crime and cannot afford a lawyer, the court must appoint one for you. That right comes from the Sixth Amendment and the U.S. Supreme Court’s decision in Gideon v. Wainwright (1963), and it applies to any charge that carries potential jail time. 

Three practical points: 

1. Eligibility is financial. The court screens your income and assets; qualifying is about ability to pay, not the seriousness of the charge. 
2. You do not choose your lawyer. Appointed counsel is assigned. If the relationship breaks down, your remedy is a Marsden motion (asking the judge to replace appointed counsel), and judges grant those only for serious breakdowns, not preference. 
3. Appointed counsel handles the criminal case. Related civil matters, such as the DMV’s separate license suspension after a DUI arrest, are generally not covered. If you want representation at a DMV hearing, that is typically private-counsel territory. 

San Mateo County Is Different: The Private Defender Program 

Here is the fact that makes the standard “public defender vs private attorney” article inaccurate locally: San Mateo County has no public defender’s office. It is the only California county with more than 500,000 residents that never established one. 

Instead, since 1968 the county has contracted with the San Mateo County Bar Association to run the Private Defender Program (PDP). When the San Mateo County Superior Court appoints counsel for someone who cannot afford a lawyer, the case goes to a PDP panel attorney: a private criminal defense lawyer, many with decades of experience, paid through the program. The panel includes more than a hundred attorneys handling everything from misdemeanors to serious felonies and juvenile matters, and the program has received national recognition for indigent defense, including the American Bar Association’s Harrison Tweed Award. 

What this means for your decision: 

• “Public defender” in San Mateo County already means a private criminal lawyer, assigned and paid by the program rather than chosen and paid by you. 

• The core trade-offs remain. You still cannot choose your PDP attorney, caseload and program compensation still shape how much time your case gets, and switching still requires either hiring private counsel or a Marsden-type showing. 

• Quality is real. The PDP is a respected program. The question is not whether assigned counsel is competent; it is whether assignment, rather than selection, serves your particular case. 

Public Defender vs. Private Attorney: The Real Differences

Two rows deserve emphasis. Timing: appointed counsel enters at arraignment; a private lawyer can work the window before charges are filed, which in some cases influences what gets filed at all. Scope: the collateral pieces (license, employment, immigration) fall outside the appointment and are often where professionals have the most to lose. 

Myths Worth Dropping 

“Public defenders are bad lawyers.” False. Indigent-defense attorneys try more criminal cases than almost anyone in the building and know the local courts intimately. In San Mateo County, PDP panel members are experienced private criminal lawyers by definition. The constraint is time, not talent. 

“Private lawyers always get better results.” Also false as a blanket claim. No ethical lawyer can promise a better outcome, and paying a fee does not change the evidence. What a private lawyer can reliably offer is more of their time and your choice of specific expertise. 

“If I hire a lawyer, the court will think I’m guilty.” No. Courts see retained and appointed counsel every day and draw no inference from either. 

“The public defender works with the DA against me.” Familiarity between defenders and prosecutors is how negotiated outcomes happen everywhere; it benefits defendants far more often than it hurts them. This is true of experienced private counsel too. 

When Staying with Appointed Counsel Makes Sense 

• The charge is a lower-level misdemeanor and the realistic outcomes cluster tightly regardless of counsel. 

• Money is genuinely tight; a strained family budget is a real cost that belongs in the decision. 

• Your assigned attorney is engaged, communicates, and has a plan; competent representation you already have beats hypothetical representation you cannot fund. 

• The case will resolve at an early stage with a standard disposition. 

When Hiring a Private Attorney Makes Sense 

• The stakes are asymmetric: felonies, strike exposure, domestic violence charges with their lifetime consequences, DUI cases where the license and insurance fallout dwarfs the fine, or any charge threatening a professional license, security clearance, or immigration status. 

• The case rewards time: contested evidence, weak stops or searches, recanting witnesses, or negotiation leverage that only develops when someone reads every page and watches every minute of footage. Our guide on how criminal charges get dismissed shows how time-intensive that work is. 

• The clock matters: pre-filing advocacy, the 10-day DMV deadline after a DUI arrest, or an arrest warrant situation where early counsel shapes what happens next. See what to do if you have a warrant. 

• You need one person handling the whole problem: court case, DMV, licensing board response, and eventual record relief.

Can You Switch? 

From appointed counsel to a private attorney 

Yes, at almost any stage. Your new lawyer files a substitution of attorney and takes over. The practical limit is timing: courts can deny a substitution that would delay a trial about to start, so the earlier you decide, the cleaner the switch. 

Replacing one appointed lawyer with another 

Much harder. There is no right to a different assigned attorney because of style or personality. A Marsden motion requires showing the judge a genuine breakdown in the attorney-client relationship or inadequate representation, and it is heard privately, without the prosecutor. Judges deny most of them. 

From private counsel back to appointed 

If your funds run out mid-case, tell the court; if you now qualify financially, the court can appoint counsel (in San Mateo County, through the PDP) going forward. 

What a Private Defense Attorney Costs 

Honest answer: it varies too much for a reliable number, and any article giving you one precise figure is guessing. What actually drives the fee: the charge level and count, whether the case is headed toward motions or trial, the attorney’s experience, and the county’s market. Common structures are flat fees by stage (pre-filing, pretrial, trial) and hourly billing against a retainer. 

Three protections when you shop: 

1. Get the fee agreement in writing. California law generally requires a written fee agreement in non-contingent matters where total fees will exceed $1,000, and you want one regardless. 
2. Ask what the fee includes: investigators, experts, motions, trial, and the DMV or licensing pieces are sometimes separate. 
3. Compare consultations, not just prices. Most defense lawyers, including our office, offer free consultations; how a lawyer analyzes your facts in that first conversation tells you more than the number does. 

A Perspective from Both Sides of the System 

Thomas Greenberg spent years as a Deputy Public Defender in San Mateo County before opening his private practice in Redwood City, which means he has worked both sides of this exact question: he has carried the appointed caseload, and he now runs a practice built on the time and continuity that caseload makes difficult. That history shapes an honest first consultation. In some conversations the right advice is that assigned counsel can handle the matter well and hiring privately would buy little; in others, the early hours a private practice can spend on a case are precisely what change its direction. Outcomes always depend on the facts, the court, and the prosecution, and no lawyer, appointed or retained, can promise a result. 

Deciding for Your Case 

The choice is not public versus private in the abstract; it is a specific case, a specific budget, and a specific set of consequences. If you or a family member is facing charges in San Mateo County, a free consultation with the Law Offices of Thomas Greenberg will give you a straight assessment: what the realistic outcomes look like, what appointed counsel through the Private Defender Program can be expected to do with it, and what private representation would add in your particular situation. Call (650) 242-0021. If money is the obstacle, say so; knowing all your options, including the PDP, is part of an honest answer.
