I would like to thank the Board of Supervisors for entrusting me to serve as the next Chief Executive Officer of Contra Costa Health. I look forward to working with you.

My work is guided by a commitment to health equity, evidence-based care, and partnering with the communities we serve. This includes a background in public health, clinical medicine, policy and research. Most recently I served as Director of Health in San Francisco.

This is an important time for Contra Costa Health. While challenges lie ahead, I am confident we will continue to provide dignified, high-quality care and services for all Contra Costa residents, particularly the most vulnerable.

I thank Dr. Ori Tzvieli, the executive team, and all of you for your tireless work on behalf of our patients, clients and community. I am excited to listen, learn and work alongside you as we advance the mission of Contra Costa Health.

National Health Center Week (Aug. 3-9) is a moment to recognize and celebrate the incredible impact that clinics, both our own at CCH and those of our community partners, have every day in our community.

Our ambulatory care clinics form the cornerstone of our county’s health safety net. Every weekday we serve nearly 1,900 patients, providing everything from primary care and obstetrics to dental services and chronic disease management, with many medical and surgical specialties. Our numbers speak volumes about the trust placed in us and the essential role we fill in Contra Costa County.

Health centers are the anchor points that tie us to the community. They do more than offer high-quality care. They signal that safe, accessible, culturally responsive healthcare and services are available in neighborhoods where they are needed most. Our care also reaches far from a traditional doctor’s office – such as our school-based, shelter-based and mobile clinics.

That accessibility is more crucial than ever. Our physical footprint translates directly into health equity, ensuring that Medi-Cal and CCHP members, uninsured people, and marginalized populations receive care without barriers.

We are also proud of how many of our Health Centers have earned “Committed to Care Excellence” recognition from the national organization, Age-Friendly Health Systems: Antioch, Bay Point, Concord, Martinez, Pittsburg and West County. It’s just one example of how we combine evidence-based practices with patient-centered compassion.

To everyone who makes it happen, from front-desk staff to providers, care coordinators, nurses, social workers, support staff and administrators – thank you. It's your dedication that turns appointments into meaningful connections, screenings into long-term relationships, and care into a statement that everyone counts.

As National Health Center Week unfolds, I hope you feel a real sense of pride in what we accomplish together.

With deep appreciation,

Dear CCH Team,

Many of you have asked how best to support patients and clients in this uncertain political moment, especially those worried about immigration enforcement.

At last week’s Board of Supervisors meeting, about 100 protestors attended to speak out during the Sheriff’s annual disclosure about how his office interacts and shares information with Immigration & Customs Enforcement (ICE). The public is paying close attention – so is CCH, and the people we serve.

At Contra Costa Health, our mission is to provide health care. Our staff do not assist with enforcement actions. We do not allow access to nonpublic areas of our facilities without a valid judicial warrant. To ensure safety, our staff are also instructed not to physically intervene if agents do enter without consent. The guidance in our earlier training video remains in effect.

CCH safeguards sensitive information within our health system and adheres to state and federal privacy laws, such as HIPAA. However, most of our services are funded by Medi-Cal and, as part of program operations, our local Medi-Cal data is shared with the State of California. The state, in turn, is required to share certain eligibility information with the federal Centers for Medicare & Medicaid Services (CMS). This includes names, addresses, dates of birth, and other identifiers.

We now know that the CMS have shared patient information with immigration enforcement. This is beyond our control, but we know it can raise concerns for our patients about their privacy and safety. The state of California has joined a lawsuit against this data sharing.

When patients ask, please be transparent. CCH will protect their information within our system. It is important for them to know that disenrolling from Medi-Cal will not protect their information. Cancelling coverage now may only result in the loss of essential healthcare services. For patients concerned about visiting our facilities, it is also important to share how to receive other kinds of care, such as telehealth or mobile clinic services in their area.

For those with questions about their rights or immigration status, our Employment & Human Services Department maintains an excellent Immigration Resources web page. I encourage us all to familiarize ourselves, so we can familiarize people in our care.

We remain committed to our mission: to care for and improve the health of all people in Contra Costa County with special attention to those who are most vulnerable to health problems. It is critical that patients should be able to seek and access medical care without fear.

Thank you for continuing to care for our community with compassion and integrity.

With Appreciation,

As we are getting ready for the upcoming Board of Supervisors agenda, I wanted to take a moment to acknowledge our Finance Procurement team, and especially the Grants & Contracts unit, for handling the unseen work that keeps Contra Costa Health running.

With the change in the fiscal year and the necessary management of our department’s many, many agreements and financial obligations, this is one of the busiest times of year for Finance. Next week alone, the Board will review 80 items (!) submitted by our team. That, following 56 just last week.

Individually most of these are routine administrative transactions. Collectively, they are the stuff that makes up Contra Costa Health. Every service contract, software license, and staffing agreement keeps us moving forward – and our G&C team is processing an incredible 455 contract renewals as we speak, tied to the June 30 end of the last fiscal year.

Of course, this work would not be possible without the partnership and collaboration of dedicated staff across all branches and divisions. Your responsiveness, preparation, and attention to detail keep this complex process running smoothly.

We often highlight the work of our frontline staff, as we should, but this is a moment to also celebrate the quiet brilliance of the teams who secure the tools, people, and partnerships that keep us working.

Thank you to the entire Procurement team, everyone in Grants & Contracts and all of Finance, for that matter, for the long hours, precision, and professionalism you bring to this work.

Your efforts may happen behind the scenes, but they are essential to fulfilling our mission, to care for and improve the health of all people in Contra Costa County, with special attention to those who are most vulnerable.

Congress last week passed House Resolution 1, the sweeping federal budget bill that includes significant cuts to Medicaid. Combined with changes in the state budget, these cuts could result in more than 50,000 Contra Costa residents losing healthcare coverage over the next several years.

Our health department is anticipating budget reductions of up to $200 million per year, which will be gradually implemented, with the most significant impacts beginning in 2027. This will directly impact our community.

At a time when our patients need a strong community healthcare system the most, we will be challenged by the loss of thousands of insured patients and hundreds of millions in revenue, as funding for outpatient and emergency care is reduced or eliminated. We also expect that many of our clients will be affected by reductions to CalFresh (SNAP), deepening hardship for the communities we serve.

Despite these challenges, our mission remains unchanged. We must care for those who need us most. We are actively planning for these impacts – improving efficiency, strengthening partnerships, and aggressively advocating for the resources we need to keep our community healthy.

That includes working closely with the Employment & Human Services Department to help ensure as few residents as possible lose coverage. We are also creating a cross-divisional working group to reinforce the basic health care program – our county program that helps serve the medical needs of those with no insurance.

I want you to know that leadership is fully aware of the stress these changes cause on all of us – both our community and our staff. I also want you to know that at least for the immediate future, we do not anticipate layoffs or large-scale, budget-related reductions in service.

Contra Costa Health employees are the beating heart of our county’s healthcare system, and your work matters now more than ever. We are committed to supporting you and protecting the vital services our community depends upon, no matter the challenges.

• View the 2025 PIT count summary

• Homelessness decreased by more than 30% in Central, East and West County.

• Temporary and permanent housing beds increased by 34% since 2023.

• Substantial local progress, including a 60% drop in Martinez, 46% in Richmond and 40% in Antioch.

These results underscore the importance of the services we provide to support some of our community’s most vulnerable residents.

CCH is working hard on many fronts to create more housing opportunities. In recent years, we’ve opened two Homekey facilities, including El Portal Place, which began welcoming residents in October. We know the work is far from over, but we also know it’s making a difference.

Following up on from our message about the May State budget revision, I wanted to give you a brief update on where things stand now.

Since May, the Legislature and Gov. Newsom have continued negotiating and the State passed its 2025-26 budget, which will take effect July 1. While this latest version of the budget reflects several compromises negotiated by lawmakers, it will still have a concerning impact on our community, especially adult undocumented immigrants. Here are a few of the health-related line items:

• The State will re-establish asset tests to determine Medi-Cal eligibility. Individuals with $130,000 in assets and couples with $195,000 in assets won’t be eligible for Medi-Cal anymore.
• Starting Jan. 1, 2026, the state will freeze enrollment in Medi-Cal for adults with undocumented immigration status (although those who already have Medi-Cal will be grandfathered in).
• Undocumented adults still on Medi-Cal will have to pay a monthly $30 premium to retain their benefits (down from $100 in the Governor’s May proposal) after Jan. 1, 2027.
• Dental benefits for undocumented adults on Medi-Cal are being eliminated after July 1, 2026.
• The State will also end enhanced reimbursement rates for undocumented adult visits at our Federally Qualified Health Centers starting July 1, 2026. As I mentioned before, this means we would receive much less funding for the same care.

There are roughly 50,000 adults on Medi-Cal with unsatisfactory immigration status in Contra Costa who are patients at CCRMC & Health Centers. It will be critical to get the uncovered portion of this population enrolled in Medi-Cal before the January 1 cutoff date.

I am worried that as a result of the changing Medi-Cal rules we will see more people delaying care and ending up in our emergency room – or worse -- when their conditions become critical.

It’s still to be determined exactly how all these changes will affect our operations. Obviously, some parts of the department (such as the Health Plan and our delivery systems that are funded largely by Medi-Cal) will be more impacted than others (regulatory programs like Environmental Health that rely on local fees). Meanwhile, the federal budget is still being negotiated and we don’t yet know how that will further change our outlook.

As things become clearer, department leadership will remain in contact with you all and share the latest information. Whatever happens, just remember -- our mission will remain the same and we will proudly continue to be the safety-net provider for our community.

Juneteenth marks the day in 1865 when Union troops arrived in Galveston, Texas, to enforce the liberation of the last enslaved people in the Confederacy, more than two years after the Emancipation Proclamation. Recognizing the significance of this historical moment, Juneteenth was declared a federal holiday in 2021 to honor the resilience and contributions of African Americans and to promote awareness of the ongoing struggle for racial equality. As a federal holiday, it serves as a reminder of the importance of freedom, justice, and the need to confront the legacy of slavery in America.

That legacy includes the consequences of delayed justice – where rights and protections exist on paper but are not shared, enforced, or accessible to those who need them. As a public health system, we must confront that history by ensuring our services, decisions, and information reach everyone with intention and equity.

This Juneteenth, I want to reaffirm that Contra Costa Health (CCH) is committed to upholding dignity, safety, and equity for all. We must not hinder the sharing and provision of care. Instead, let us be intentional in our outreach and services. Let us stand united for everyone and renew our commitment to creating a health system where access to quality healthcare and achievement of health equity are universal rights, not delayed or conditional.

Through our Black Infant Health program, Perinatal Equity Initiative, and other similarly focused efforts we are actively addressing systemic health disparities with culturally responsive, community-driven care. These programs connect families to essential resources, alleviate stress and isolation, and foster safer, more empowering pathways to wellness. 

This commitment to equity is an integral part of our broader work, encompassing our collaborations with community organizations, our internal equity initiatives, and our engagement with the Office of Racial Equity and Social Justice. 

Juneteenth calls us to celebrate progress, reckon with history, and recommit to a future where health and dignity belong to everyone. Thank you to each of you who helps make that future possible. 

In celebration and gratitude,
