Born and raised in Venezuela by Dominican parents, Rosa came to live in the U.S. in her teens.

Rosa has a long history of participating in numerous charitable programs, fundraisers, and non-profit organizations such as the United Way, and has worked closely with local health departments.

Rosa first joined the Board in 2012 and sees LCW as one of the most solid and finest organizations in our community. In her own words, “LCW is an excellent recipe for what the community of Lawrence needs and I want to be part of all the positive things that LCW does.” Rosa has a Bachelor’s degree in Health Science from Hodges University and graduated from the Greater Lowell Vocational School in Tyngsboro, MA, as a Registered Medical Assistant.

Maria Fina

Vice President

As an immigrant from Terceira, Azores, Maria’s family relocated to Lawrence in January 1972. Maria is proud to share that she spent her youth being raised in our city and is a graduate of Lawrence High School Class of ’87.

Maria began her career in the Financial Industry in 1988 as a Teller working for Lawrence Savings Bank. It was during the early 1990s when she had the opportunity to be part of LCW’s first IDA program. In her own words, Maria says, “I knew from that moment that this was the organization that I would always want to be involved with. Being raised in Lawrence gave us an opportunity to still maintain our traditions, however growing up with immigrant parents with limited English was certainly a challenge and the services that LCW offers to the community are rewarding.”

Maria was SVP/Relationship Manager of the TD Bank Essex Street branch for 20 years and in 2024 moved on to a new role at North Bank.

Maria and her husband have been married for nearly 30 years and are the proud parents of a wonderful young man who graduated Central Catholic High School Class of 2016. Maria treasures the time she spends with family and friends, enjoys traveling, and soaking up as much beach time as she possibly can.

Armand Hyatt, Esq.

Pro Bono General Counsel/Board Member

Armand is one of the Founders of LCW and has continuously served on the Board since 1986. Armand’s contributions over the years as pro bono Legal Counsel and Chair of the Board’s Real Estate Development Committee—as well as prior Board President, Vice President and Clerk—are incalculable and may be unmatched in the annals of community development in MA. In addition to countless hours of strategic and tactical advice and work to advance LCW’s real estate efforts, Armand has represented LCW—and often some of its members—in various legal matters. In 2002, LCW established the “Armand Hyatt Young Professionals Scholarship” fund at its annual meeting.

Armand was raised and schooled in Lawrence and has maintained his primary law office (“Hyatt & Hyatt”) in the North Common neighborhood of his boyhood in Lawrence since 1976, after graduating from University of San Diego School of Law. He is admitted to practice in Massachusetts, California and New Hampshire.

Armand was one of a handful of affordable housing activists who fought for and won resident-based struggle in the North Common neighborhood which began in 1981 and successfully overturned an illegal land disposition process, then secured the acquisition and ultimate development of 140 units of affordable housing on a large urban renewal site. That successful struggle led to the founding of LCW under its original name: Heritage Common CDC.

In addition to his commitment at LCW, Armand has been the long-time President and coach in the Amesbury Youth Rotary Basketball League, a former Director of the Merrimack Valley YMCA and former adjunct lecturer at Merrimack College, as well as continuing on as a Lector, Religious Ed teacher and member of the Parish Pastoral Council at Holy Family Parish in Amesbury and a music minister at St. Basil’s Cursillo retreats. He has been an active “Big Brother” since 2003.

Armand was recognized by the NYSE as Executive Producer of PERFECT CRIME, the Off-Broadway thriller which has become the longest-running non-musical play in the history of New York theatre. He also partnered in the refurbishing of historic space in Times Square to establish a new Theater Center, including negotiation of the lease and obtaining waiver from the union to allow an Off-Broadway production to play in that new space at 1627 Broadway.

On September 26, 2008, the City of Lawrence officially declared “Armand Hyatt Day” as he was presented with various forms of recognition for his work within the City:

– House of Representatives proclamation “in recognition of uncompromising dedication to Lawrence CommunityWorks and the City of Lawrence”

– MA State Senate proclamation “in recognition of passionate advocacy, tireless commitment and heartfelt dedication to LCW and the revitalization of Lawrence”

In 2014, the U.S. House of Representatives issued a Certificate of Special Congressional Recognition for Armand’s role in “helping to establish LCW and his vision for a healthy and clean Spicket River.” In 2019, the U.S. Senate issued Armand a Certificate of Special Congressional Recognition for “outstanding and invaluable service to the community.” In 2019, the Lawrence Bar Association presented Armand its “Lifetime Achievement Award” for outstanding service to the community in the field of affordable housing. In 2020, the Lawrence History Center recognized Armand as its Eartha Dengler Award recipient.

Jacoba Olivero

Board Clerk

Jacoba was born in La Isabella, Puerto Plata, Dominican Republic. At an early age, she knew she wanted to work with people. Jacoba studied education and psychology and began working as a teacher in the late 1970s. In 1982 she emigrated to the United States. “When I moved, I did not know any English and moved to a country and a city where I did not know anyone besides my husband’s brothers. We lived in a small apartment in Lawrence and life was difficult during this time because I could not communicate with anyone,” Jacoba remembers.

After a few years, Jacoba began taking English classes at Northern Essex Community College and soon was able to find a job as a housekeeper with a big company and eventually became a manager. “Life was hard and often I needed to work more than one job just to get by … From the beginning, I knew that in order to succeed my children needed to have a good education. I instilled in them the idea that through hard work and effort all things are possible. I also taught them to love, respect, and help those in need in our community both in the United States and in the Dominican Republic.”

In 2010, Jacoba participated in a program offered by LCW and became a volunteer. She is now a full-time student at NECC studying English and on the road to becoming a counselor.
