Economic-driven solutions to accelerate inclusive and sustainable growth

Arrow Down


Halvatzis and Associates, LLC., is a minority and women-owned business located in Denver, Colorado. 

Our Beliefs

We believe that everybody deserves the opportunity to thrive.

We believe that we have a once-in-a-lifetime opportunity to address the inequities in our society as we transition to a cleaner economy and emerge from our current health crisis.   That is why we partner with organizations in the clean energy and economic development sectors to enhance their ability to more effectively improve the economic outcomes of low and medium-income populations.  


We believe we have the opportunity to reimagine our systems and reset our social constructs.

Our Mission

Our mission is to improve the economic outcomes of low and medium income populations.   We work with renewable energy providers, economic development organizations, policy, and education partners to reduce systemic barriers inhibiting low and medium income people from accessing the benefits of the clean energy transition.  We provide the economic research, analysis, business strategy, and policy arguments that help organizations advance the effectiveness of their programs  and policy advocacy efforts. 

What Makes us Unique

All across the U.S., forward thinking organizations are trying to solve some of our Nation’s toughest problems around sustainability, equity and quality of life. Yet, without deep economic insight from a trusted source  has knowledge of the communities we are trying to reach, our solutions will fall short of meeting the unique needs of individual communities.  Halvatzis & Associates, LLC, has a deep understanding of the segmentation in the Hispanic market, provides in-depth analysis, and culturally relevant solutions.
