Her Story

About Dawn

Dawn Capotosti is an Environmental Health Unit Manager with Yavapai County, where she provides leadership in environmental health regulation, public health protection, and compliance oversight across residential and commercial development. In this capacity, she is responsible for ensuring that county environmental health standards are consistently upheld, with a strong focus on safeguarding groundwater resources, preventing contamination, and supporting safe, sustainable community growth. Her work bridges technical regulatory review with public health protection, helping to ensure that development projects align with state and county environmental codes and long-term community safety goals.

Her professional journey is distinctive and shaped by both clinical and regulatory experience. She began her career in nursing, working in emergency room and trauma settings where she provided direct, high-acuity patient care in fast-paced, high-pressure environments. This foundation strengthened her ability to assess risk, respond quickly to critical situations, and maintain a strong focus on patient and public safety. While later working in county government within the Assessor’s Office, she was repeatedly exposed to postings for registered sanitarian roles—a profession she initially had not encountered. Intrigued, she independently researched the field, learned about its scientific and regulatory requirements, and chose to pursue certification. After successfully passing the credentialing exam, she transitioned into environmental health work, building her expertise from the ground up in environmental codes, statutes, and regulatory enforcement through hands-on experience and intensive on-the-job learning.

In her current role, she serves as a key environmental regulator focused on groundwater protection and public health risk prevention. She reviews development plans and permitting submissions through building and development services to ensure that wastewater systems are properly designed, safely implemented, and compliant with environmental regulations. Her oversight helps protect drinking water sources, surface water systems, and recreational environments from potential contamination, ensuring the long-term safety of the community’s natural resources. By evaluating both residential and commercial projects, she plays an essential role in balancing development needs with environmental stewardship, reinforcing public trust in the safety and integrity of county infrastructure systems.

Ten minutes with Dawn

01What do you attribute your success to?

I never give up. I don't take no for an answer. I really believe if I'm doing something that is truly beneficial for the public or for public health, that it's right to keep pushing to do it. Sometimes elected officials or management don't understand because they don't come from the technical background or the science background, but there really is a need for people who have the expertise to stand their ground and to really say, no, it needs to be done this way because this is for the safety of the public. I truly, every day, with the best of intentions, always want people treated kindly and fairly. People know I'm a straight shooter. I'm also the kind of person where if you come to me with a problem, I love to brainstorm and think of solutions. I'm always willing to sit down with somebody and be like, okay, let's think of everything under the sun we can think of, and then start knocking out what's not going to work, and try to come up with a solution. I think that's probably my biggest avenue to success. I just don't give up, I just keep going. The day I stopped learning, you might as well just throw me in the casket. I want to learn every day.

02What advice would you give to young women entering your industry?

My biggest piece of advice is if you are in college and you are studying science, science of any kind, that you have some kind of natural background science, really look at the registered sanitarian role. Most people have never heard of it, they have no idea what it is, and they don't even realize that with their amazing science background, that this is an industry they can get into. There's kids that apply to medical school who maybe don't get in, but you know what, they can come in and challenge this certification test and start working as a sanitarian while they're trying to get back into med school. Whatever it is, there's so many options in this role for people who love science or have a science background, but they're not told about it. My biggest thing is just get the word out there about this role and position, and the more we get the word out, the better income for everybody. It's just a win-win. Don't be afraid to speak up and participate fully in discussions.

03What are the biggest challenges or opportunities in your field right now?

Political interference, absolutely. Political interference, even at the county level, which is difficult because not only are you trying to be a regulatory agency, which is just by code and statute, but you have a lot of political pressure on you as well. That is the biggest challenge, and it seems like in the last few years, the pressure's getting more and more and more, and I think that's just the climate across the country. It's the most challenging thing to maneuver, staying true and authentic to your regulations and working the best you can with people in the public sector who understand that nobody's singled out, everybody's treated fairly and equitably. But it's difficult. You get the political pressure, right? They're trying to make things better for their constituents, but at the same time I don't have any wiggle room. It's by code, so that's the hardest part.

04What values are most important to you in your work and personal life?

I am passionate about service and volunteerism. I believe meaningful change happens when individuals are willing to contribute their time, expertise, and energy to causes larger than themselves. I volunteer for the American Legion every Friday serving meals to veterans, and every Sunday I volunteer at the Humane Society walking dogs. I am getting ready to start a nonprofit organization called the Arizona On-Site Wastewater Advisory Committee, which I hope will provide education, advocacy, and support within the wastewater and environmental health sectors. My vision is to create a resource that supports professionals, policymakers, and communities while promoting best practices that protect groundwater and public health throughout Arizona. I truly believe if I'm doing something that is truly beneficial for the public or for public health, that it's right to keep pushing to do it. Every day, with the best of intentions, I always want people treated kindly and fairly.
