Current members:
Andy Dang, MS, MPH
Internal Evaluator
Los Angeles County Department of Public Health
Hi fellow TEA members! I am an internal evaluator, co-lead of the Research and Evaluation Unit, and research analyst for the Los Angeles County Department of Public Health, Tobacco Control and Prevention Program. For more than 15 years, I have worked in the field of tobacco prevention and smokefree policies in many capacities – conducting research on various environmental tobacco smoke studies involving secondhand smoke exposure in multi-unit housing and public outdoor areas, developing survey protocols and instruments for field data collection, and overseeing evaluation-related activities for our community partners. I received my BS in Public Health Sciences from the University of California, Irvine (2009), my MPH with a concentration in Environmental Health from San Diego State University (2015), and most recently my MS in Epidemiology from Columbia University (2025).
Outside of work, I enjoy cooking, the great outdoors, and taking my dog out for long walks.
Becca Carsel
External Evaluator
Carsel Consulting Group
Hello! I am the external evaluator for the County of San Luis Obispo Public Health Department’s Tobacco Control Program. I have served as their external evaluator since 2017 and have participated in the Tobacco Control Alliance (TEA) since its inception. I really value opportunities for evaluators to come together, as we so frequently work in isolation. Because of this, I think TEA plays an important role in connecting and supporting tobacco control evaluators.
In addition to my tobacco control work, I support government agencies and non-profits with program, initiative, and advocacy evaluation; grant writing; staff education and training; and facilitation and strategic planning. My evaluation work is primarily in the public health, mental health, and social services sectors. I feel fortunate to work often with a small group of independent consultants, which allows me to collaborate with and learn from my colleagues. When I’m not trying to get caught up on my work and my side interests, I like to be out in nature, reading a good book, or enjoying my husband’s amazing cooking.
Denise Cintron Perales, MS
External Evaluator
Perales & Associates Evaluation Services (PAES)
Hi, TEA members. I am one of the founding members of TEA. I also serve as an external evaluator and principal with Perales & Associates Evaluation Services (PAES). For 29 years, PAES has provided a wide range of public health program evaluation and strategic planning services to California state and local public health agencies, as well as non-profit community-based organizations.
My role as an external evaluator and specifically, my tobacco-prevention experience, includes designing effective program evaluations, evaluating local, regional, and competitive-grantee projects, and detailing their policy-based accomplishments in evaluation reports and presentations. Being engaged in many of the state’s anti-tobacco battles and helping to protect people of all ages from the dangers of tobacco is a cause that I truly believe in.
Before joining PAES, I served as a project director and executive director for not-for-profit organizations. Having worked at the grassroots level, I know the challenges associated with implementing programs and conducting effective evaluations. I hold a BS in Social Work from Florida State University and an MS in Organizational Development from the University of San Francisco.
When I’m not evaluating public health programs, you can find me in wine country, traveling, or tending to my garden.
Ken Einhaus
Senior Research Associate, Project Co-Director & External Evaluator
Center for Applied Research Solutions
Hello TEA Community! I am an external evaluator, project co-director, and analyst who joined GrEEN TEA in April 2024. I have worked in CTPP tobacco control evaluation for 9 years with a competitive grantee in Orange County and 4 years with the San Mateo County LLA. Our work has promoted policy change in the areas of smoke-free multi-unit housing, smoke-free cities, tobacco retail licensing, and flavored tobacco sales. I have designed and analyzed post-education tests, KIIs, public intercept surveys, observation surveys, young adult tobacco purchase surveys, focus groups, media activity records, and policy records. I have written CTPP Brief and Final Evaluation Reports. Additionally, I have evaluated smoking and vaping prevention projects, projects supporting youth physical fitness and nutrition, a project promoting youth leadership and civic engagement, a project serving children of prisoners, a coalition working to reduce alcohol, tobacco, and marijuana use among 7-12 graders, and a program promoting student mental health across the California Community College system. I was lead author of the 2018 LGBTQ Population Evaluation Guidelines developed for the California Reducing Disparities Project, funded by CDPH’s Office of Health Equity. Its SOGIE measures were translated into Hmong, Khmer, Korean, Mixteco, Samoan, Spanish, Tongan, and Vietnamese for use in the initiative’s cross-site evaluation.
TEA Quarterly Meetings have increased my understanding of CTPP expectations and provide valued community, and I’m passionate about community-of-practice teambuilding. Outside work I enjoy tossing with my three beagles, growing food and flowers, playing keyboards, hiking, and chilling by the Russian River.
Linda M. Bosma, PhD
External Evaluator
Bosma Consulting
Hello TEA community! I completed my PhD in Evaluation Studies and founded my evaluation practice twenty years ago, after years of work as a research and community organizer. I work as an external evaluator, primarily with a focus on tobacco and alcohol initiatives that engage community members through policy and engagement. I am the external evaluator for two CTPP initiatives: SPARC, the statewide coordinating center for Asian American and Native Hawaiian and Pacific Islander communities, and Eden Youth Center’s Tobacco Endgame. My projects include federal, state, and local initiatives, working with non-profits, coalitions, government agencies, and foundations. When I say I am an external evaluator, that is really true, as I’m based in Minnesota! I work in many states, but I’ve been volunteering and working with California groups since 2000.
I was drawn to evaluation when I was working in non-profits and observed that funders were asking questions that didn’t get at the most meaningful aspects of community-based efforts—I wanted to be in a position to help groups articulate the value of their efforts, to demystify the evaluation process, and help them use findings to improve and advocate for their work. I also believe evaluation can be fun, and look for opportunities to bring meaning and joy to the work. I’m excited to be part of GrEEN TEA and to continue to build a supportive community of tobacco control evaluators!
Shristi Reddy, MPH
External Evaluator
CAMI Consulting, Inc.
Hello TEA members! I currently serve as an external evaluator with CAMI Consulting, Inc., and as a health educator specialist with The LOOP at UCSF. I earned my Master of Public Health with an emphasis in Health Education from San José State University.
For more than ten years, I’ve worked in tobacco control as an external evaluator, supporting Local Lead Agencies, competitive grantees, and statewide partners. My experience includes developing and adapting assessment tools, tracking and maintaining databases, analyzing data, and producing summaries, brief, and final reports. I’ve also supported dissemination efforts, including presentations at the American Public Health Association (APHA) conference.
I’ve really enjoyed participating in TEA meetings and have learned so much from my fellow evaluators. I bring my experience, perspective, and enthusiasm to the GrEEN TEA board.
Outside of work, I love exploring national parks and have visited 21 of the 63 parks so far. I also enjoy a good cup of coffee and love finding new cafes whenever I travel.
Stergios (Steve) Roussos, PhD, MPH
External Evaluator
Alliance for Community Research and Development (ACRD)
Hi TEA Community! I am an external evaluator for CTPP programs and a member of GrEEN TEA. I love being a community-based researcher working with diverse people to address local concerns. For nearly 30 years, I have had the privilege of working with academic and community teams to understand and improve conditions that improve quality of life, especially with our most vulnerable and underrepresented groups. Growing up in a pro-tobacco culture, I have been a tobacco prevention advocate most of my life, doing my best to prevent tobacco use from taking my loved ones. I have been a tobacco prevention researcher since 1993 and supporting CTPP-funded local agencies and competitive grantees since 2004. In 2018, I was thrilled to lead a team to develop "Fighting Flavored Tobacco: A Best Practice Guide for Developing Local Policy Campaigns to Restrict the Sale of Flavored Tobacco Products in California." I love working with gritty tobacco prevention teams serving under-resourced communities most targeted by Big Tobacco. There is a lot of joy in using good evaluation to pass local tobacco-prevention policies. The Tobacco Evaluator Alliance – TEA – is a wonderful way to learn and advance our tobacco prevention goals. I am really glad to be in TEA together.
Sue Haun, MA
External Evaluator
Strategies By Design
Hello TEA members! I am an external evaluator and a founding member of GrEEN TEA. As a private consultant, I have over 35 years’ experience in qualitative and quantitative research and working with public health departments, and nearly 30 years in tobacco prevention evaluation, working with both Local Lead Agencies and competitive grantees. As a private consultant, I have designed a variety of assessment tools, developed numerous studies and final evaluation reports, and designed numerous single- and multi-year evaluation plans. I’m also a co-author of the California Tobacco Control Evaluation Guide, the Tell Your Story Guidelines for Preparing Useful Evaluation Reports, Evaluating Local Policy Adoption Campaigns in California: Tobacco Retail License (TRL) Adoption (published in the Journal of Community Health) and Facilitators And Barriers to Passing Local Policies That Prohibit the Sale of Flavored Tobacco Products: Qualitative Analysis of Strategies Implemented by 36 Public Health Agencies in California 2017-2021 (published in Preventing Chronic Disease).
With an MA in Organization Development (OD), I am personally and professionally passionate about the Tobacco Evaluator Alliance (TEA). Never before has there been such an entity in California for CTPP-funded evaluators. We now have a place where we can come together, share what works, provide support to one another and be part of an evaluator community!
When I’m not working, you can find me piddling around in my yard, planting and drying herbs, cooking up the yummiest-ever marinara sauce or taking a walk around the neighborhood.
