Adriana Guadana-Huizar

Adriana graduated college in May of 2021 as a first-generation student. A proud daughter of two Mexican immigrants, she earned her Bachelor of Arts in International Studies and Anthropology. Adriana interned with the Chan Law Firm in 2019, and upon graduation joined the team.

Her passion for immigration came from her family’s personal challenges within the immigration system. She vividly remembers the long, systemic hurdles of filling out immigration paperwork: particularly the language barriers, economic challenges, and sheer lack of understanding of the process.

She hopes to one day become an immigration attorney and help families like hers be able to understand and obtain immigration relief. She keeps the stories shared with her close to her heart, and fully believes it is these stories that are her drive and fuel to continue to advocate.


Miriam Arevalo

Miriam graduated from the University of Colorado Boulder in May 2022 as a first-generation student. She earned her Bachelor of Arts in Political Science and Ethnic Studies. She was born and raised in Denver, CO, and is the proud daughter of two Mexican immigrants. She enjoys working in a multicultural, multilingual environment. She is fluent in English and Spanish and has a background in French. She also enjoys traveling and learning about cultures and people.

Her passion and interest in immigration law began through her parents. She experienced firsthand the challenges and struggles that her family faced after taking the leap of faith of immigrating to the U.S. in search of the American dream. Despite these challenges, Miriam hopes to continue to aid and advocate for migrants and families as she does her own and is dedicated to the immigration field and the immigrant community.
