Diego Raul Rangel was an attorney, educator, and community activist.  He founded this law firm in 1978 and it became RANGEL, RANGEL & ASSOCIATES, when his wife, Patricia, graduated from law school.  Diego practiced law for the next 24 years until his death in 2002.   He was an advisor to many community organizations.   Among his many legal accomplishments, Diego represented the Puerto Rican Parade Committee, incorporated the Puerto Rican Police Association and was a co-founder of the Puerto Rican Bar Association.

Diego Rangel was also a volunteer youth counselor and tenured Professor at Northeastern Illinois University.  He was an adamant believer that education was the means to overcome adversities.  He encouraged and mentored many of his students; and felt a strong sense of pride when they became teachers, principals, administrators, attorneys, judges, politicians, or entered other professions or trades.
RANGEL, RANGEL & ASSOCIATES is proud of Diego Rangel’s accomplishments and continues to advocate for the advancement of the community.​
