Key Takeaways
- Leaders must operationalize environmental justice by ensuring the equitable distribution of resources while guaranteeing marginalized communities have a voice in policy decisions.
Introduction: Why Environmental Justice and Community Leadership Are Crucial in Today’s Urban Public Health
As American cities grapple with ever-more complex public health challenges, the notion of environmental justice is rapidly shifting from a theoretical concept to a daily operational necessity for health leaders. From air quality to housing safety, who benefits from—or suffers through—policy decisions isn’t just a question of science or economics; it’s one of equity, power, and collaboration. Nowhere is this dynamic more vivid than in Philadelphia, where Dr. Palak Raval-Nelson, PhD, MPH, Health Commissioner and Deputy Health Commissioner at the Philadelphia Department of Public Health, leads initiatives that directly address the intersection of community voice, government intervention, and environmental health.
In our latest podcast, Dr. Raval-Nelson shared her journey, her philosophy of public service, and the practical mechanics behind building a healthier, more just Philadelphia. This episode offers not just insights for healthcare leaders and students, but actionable frameworks for anyone serious about transforming public health through collaboration, data, and an honest reckoning with power.
Q: What led Dr. Raval-Nelson to her current role—and what sustains her commitment to Philadelphia?
Dr. Raval-Nelson’s path to leadership in public health was neither direct nor conventional. “So often in life it’s not about figuring out what you want to do, but rather figuring out what you don’t want to do,” she reflected. Born in India and immigrating to the U.S., she felt early pressure to choose between medicine or engineering. Yet, she found her passion in public health through a fortuitous turn: “My second day on the job I was able to remove expired infant formula from a bodega in Kensington. I fell head over heels in love with this profession… 28 years later I am Deputy Health Commissioner for the health department.”
Why remain in Philadelphia when higher pay and prestige beckoned elsewhere? For Dr. Raval-Nelson, it’s deeply personal. “Whenever I would travel… I would miss Philadelphia tremendously. This is my home. This is where I feel the safest and the most secure.”
Her commitment is reinforced by hands-on experience: “There’s nothing like walking door-to-door to food establishments during a pandemic to make sure folks are safe. There’s nothing like working side by side with our police officers and firefighters to make sure they have the safety gear and that we’re taking care of our city.”
Key Takeaways:
Career fulfillment comes from passion, not simply from following expected paths.
Deep roots in community and a sense of mission outweigh monetary incentives for top public health leaders.
Q: How does Dr. Raval-Nelson define environmental justice, and why does it matter in Philadelphia?
Environmental justice is often misunderstood, dismissed as mere “tree-hugging” or confused with affirmative action. Dr. Raval-Nelson sets the record straight:
“At its core, environmental justice is about having an equitable situation where there’s equal distribution of environmental goods as well as environmental bads.”
She uses a vivid metaphor:
“If we had a group of people, all supposed to run a race… the rules are: if you are a minority you take three steps back, if you are a woman you take three additional steps back… Most folks end up so far back they can never reach the finish line, while a handful reap the rewards.”
In practice, this means:
Environmental goods (clean air, green spaces) are often concentrated among advantaged populations.
Environmental bads (pollution, hazardous housing, noise, lack of parks) disproportionately impact low-income and minority communities.
Dr. Raval-Nelson adds a second, often overlooked dimension:
“It’s also about creating an ideal speech situation—when we make decisions about locating an industry, a store, or a park, the community should have a say, not just the loudest voices or those with the most resources.”
Summary:
Environmental justice means ensuring both fair distribution of environmental benefits and burdens.
It requires designing processes that allow marginalized voices to be heard and respected in decision-making.
Q: Why can’t the free market alone ensure health equity, and what is the public sector’s unique responsibility?
Dr. Raval-Nelson answers directly:
“A free market is only a free market when it’s not being manipulated… An ideal free market is like Monopoly—everyone starts with the same resources. But real life isn’t like that. Equity means someone like myself—short, maybe I need a box to stand on so I’m at the same level as everyone else.”
She challenges the simplistic notion that “the market will sort it out.” In environmental and public health issues, existing power structures, education levels, and resources shape who gets heard and who benefits.
Government’s role is to level the playing field—ensuring that decisions account for those who start at a disadvantage.
Community engagement is non-negotiable:
“Public health is defined by the public in the community. The conversation must be led by the community—what are their priorities? Then we bring in experts to match those with scientifically-supported interventions.”
List: When Should Government Step In?
When market forces disproportionately harm vulnerable populations.
When critical health resources (clean air, safe housing) aren’t equitably distributed.
When the process of decision-making excludes or marginalizes affected communities.
Q: How does the health department decide where to focus—and what gets delayed?
Philadelphia spans nearly 150 square miles and includes over two million residents with divergent needs. Dr. Raval-Nelson details a pragmatic, community-centered approach:
Start with the community:
“We have neighborhoods where the biggest issue is dog bites, others where it’s noise or lack of green space. We let the conversation start with the community’s voices.”
Expert input:
“We have tremendous experts who can translate those community needs into an agenda that also elevates health equity and environmental justice.”
Joint agenda-setting:
Community needs and expert guidance are synthesized through discussion and deliberation.
This approach is adaptive and dynamic. Some issues require immediate action; others must be postponed, depending on available resources and the urgency of the need.
Key Insight:
Balancing technical expertise with authentic community input ensures that public health priorities align with both evidence and lived experience.
Q: What metrics does Dr. Raval-Nelson use to determine if the department is making progress?
Measuring success in public health isn’t about meeting quotas. “For me personally, I’m a civil servant and I answer to the taxpayer. So what difference did it make?” she explains.
Dr. Raval-Nelson offers a case study:
Air Management Services Regulation #6 (AMR6):
Four years of cross-sector collaboration (industry, advocates, public) resulted in a new regulation covering 287 pollutants—far more than before.
“We have air monitor meters hardwired around the city… We’re capturing data on PM 2.5 and Benzene. Did the levels drop after the regulation? That’s the test.”
Results are translated into plain language and public messaging (e.g., ozone alerts during wildfires).
Lead Law Example:
All rental units now require a lead-safe certificate.
“As compliance increases, the number of kids getting lead poisoning decreases. Our goal: zero children poisoned.”
Dr. Raval-Nelson’s philosophy:
Track the data relentlessly.
Communicate progress in accessible terms.
Stay focused on outcomes—not just activities.
Bulleted List: Measuring Public Health Impact
Compare pre- and post-policy health indicators (e.g., air pollution, lead poisoning rates).
Engage in continuous public reporting.
Use real-world stories to highlight how policy changes improve daily life.
Q: What’s the best way for organizations or individuals to collaborate with the Philadelphia Department of Public Health?
Dr. Raval-Nelson’s answer is as pragmatic as it is personal:
“My staff lovingly call me Dr. Palak, and they often say, ‘Wow, you’re everywhere!’ I believe in being accessible. Sometimes we find joint collaborative moments. Sometimes the idea is better suited to another department, and I make introductions. We’re all responsible at the end of the day for this city, for where we live.”
Her advice to would-be partners:
Reach out directly—she provides her card and email freely.
Be ready to work:
“Don’t complain about the snow unless you’re going to pick up a shovel next to me and start shoveling.”
Understand that disagreements are normal, but collaboration is essential:
“We may not always agree or always find the solution, but working together we can ultimately make whatever the scenario is better.”
For organizations seeking partnership:
Clarify your goals and be ready for honest conversation.
Bring your expertise, but also be prepared to listen.
Be persistent—change is a marathon, not a sprint.
The Philadelphia Department of Public Health, under the leadership of Dr. Palak Raval-Nelson, exemplifies how data-driven decision-making, authentic community engagement, and an unwavering commitment to equity can transform a city’s health outcomes.
For leaders in healthcare, government, or the nonprofit sector, the lesson is clear: Roll up your sleeves, invite every voice to the table, measure what matters, and never lose sight of the mission. As Dr. Raval-Nelson puts it, “Problems are solutions and workflows—we just got to roll up our sleeves and get it done.”
If you’re ready to help shape a healthier, more just future for your city, the time to start is now.
I think it was just uh a little bit of shock that there was people who who don't have access to the things that we just consider Basics I agree and I think that um it's so important to be present for whatever you choose to be involved in [Music] hello everyone and welcome to the strategy of Health podcast from the American journalist Healthcare strategy I'm your host Cole Lions today we have a very special guest Dr Pak raval Nelson who is the health Commissioner of uh the city of Philadelphia and also does some other work she's an Jun Professor at Drexel University um Dr Nelson we're so happy to have you here can you please introduce yourself and tell us a little bit about your role and what you do thank you so much Cole it is such a pleasure to be here with you it's an honor to be here and just want to thank you for all that you do for public health so I have been the health commissioner here in the city of Philadelphia um leading the Philadelphia Department of Public Health we have about 1600 employees uh a large budget large responsibilities um and I've been here since just earlier this year however I have been at the health department for my entire career starting out as an intern so I have been intricately involved in many different aspects of public health for the city of Philadelphia I uh am very passionate about ensuring that we have strong public health services that are equitable um for our most vulnerable populations and I'm really privileged to serve in this role you know it really is incredible to hear that you started as an intern so many people now uh leave companies so quickly and they move you know every two to three years is the average tenure so for you to be there from internship all the way up to commision that just speaks to your dedication to the city and and to the job so that's really incredible to hear um I I wanted to ask you you know we're talking about environmental justice today and you have a background in environmental health specifically what got you interested in that specific Niche because in public health there's so many broad things you can do what drew you to the environmental side yeah that's a great question I think from a very young age I was always interested in the sciences and the biological sciences but specifically how the environment impacts human health and um you know very early on in my career as I was uh learning about the various facets of environmental health a lot of it resounded with me in terms of you know making sure that people are safe in their homes in their schools in their neighborhoods um and looking at what are the potential hazards that people are exposed to that can lead to adverse health outcomes so for me it was really about that connection between place and health and how we really work to improve the conditions in which people live work and play so that they can achieve their best health possible yeah that is that is so important the social determinant of Health like you said where where people live work and play has such a big impact on their life expectancy and their quality of life um speaking of Philadelphia you know every city has its own unique challenges what are the biggest environmental justice issues that you see facing Philadelphia right now so we have a number of challenges here in Philadelphia um you know we are a old industrial city we have a lot of legacy pollution issues um specifically around lead poisoning which has been a huge huge priority for the department and for myself personally um making sure we reduce childhood lead poisoning um we also have issues around air quality um looking at environmental justice communities that are overburdened by pollution sources whether that's industrial facilities or Transportation corridors um and then climate change is another big one right we see the impacts of extreme heat and flooding that disproportionately affect our low-income neighborhoods and communities of color um so we're really thinking about how do we build resilience and adaptation strategies that centered equity and protect those who are most vulnerable um so those are some of the key areas that we are focused on um and also access to Green Space and you know making sure that people have safe places to recreate and to enjoy nature which we know has significant mental and physical health benefits definitely definitely and I think you know with a city like Philadelphia that has such a rich history but also that old infrastructure like you mentioned lead pipes lead paint those are things that you know maybe newer cities don't deal to the same extent but it's such a pervasive issue in the Northeast and in the Rust Belt so it's great that you're tackling that um you mentioned Community engagement earlier and I know that's a big part of environmental justice how do you ensure that the community's voice is actually heard and not just heard but acted upon when you're making these decisions yeah that is critical um you know we cannot do this work in a silo we have to work hand inand with our residents and our community organizations um so one of the things we established is an environmental justice Advisory Board which is made up of residents from environmental justice communities who advise the department on our policies and programs um we also do a lot of um direct Outreach and engagement going to Community meetings hosting listening sessions um really meeting people where they are to understand what their concerns are and what their priorities are um and then making sure that we incorporate that feedback into our decision-making processes um transparency is key accountability is key um and building that trust right because there has been a history of mistrust between government and communities and so we have to be very intentional about rebuilding that trust and demonstrating that we are listening and that we are here to serve um so it's an ongoing process but it's one that we are fully committed to that's fantastic and I think that Advisory Board model is really smart because it institutionalizes that feedback loop rather than just well we'll do a town hall once a year it's like no we have a standing board of people who are living this every day so that's that's a great model um one last question for you Dr Nelson you know for students or young professionals who might be listening to this and they're passionate about environmental justice or public health what advice would you give them as they're starting their careers yeah I would say you know follow your passion um be curious be willing to learn um get involved you know volunteer inter turn um find mentors who can guide you um but really don't be afraid to speak up and to advocate for what you believe in um we need fresh ideas we need energy we need new perspectives in this field um so I would encourage young people to really embrace the opportunities that are out there and to know that they can make a difference um public health is a incredibly rewarding career um because you really have the opportunity to impact lives on a population level um so stick with it and uh and just keep pushing forward that is great advice well Dr raval Nelson thank you so much for your time today it was a pleasure speaking with you and hearing about the great work happening in Philadelphia thank you Cole it was a pleasure to be here [Music]
