MIAMI-DADE COUNTY — A Miami-Dade condo building manager was arrested Thursday on multiple charges, authorities announced.

According to the Miami-Dade Sheriff’s Office, Maria Del Carmen Alvarez-Concepcion, 57, was arrested Thursday afternoon on charges of soliciting/accepting kickback payments, organized fraud and second-degree grand theft.

An arrest report states that a current board member and homeowner at the Greynolds Park Club Condominium Association, located at 17890 W. Dixie Highway, contacted MDSO about concerns he had regarding the mismanagement of association funds by certain members of the board of directors and the on-site building manager, identified as Alvarez-Concepcion. Detectives said the board member told detectives that on Jan. 23, he was approached by a contracted vendor who reported that Alvarez-Concepcion had been soliciting and accepting kickback payments “in the form of cash and Zelle transfers.” The report states that the board member “further reported longstanding concerns regarding the defendant’s exclusive control over multimillion dollar contracts, lack of financial transparency, questionable fees, missing records, and the exclusion of certain board members from major association decisions.” According to the report, the vendor who spoke with the board member met with detectives on Feb. 13 and corroborated the information initially provided by the board member. Detectives said that the vendor claimed that between March 7, 2025, and Dec. 5, 2025, Alvarez-Concepcion repeatedly solicited and accepted kickback payments, saying that he paid her about $19,910 in cash and Zelle transfers during that time period.

Authorities said the payments were not authorized by the association and were “intentionally concealed from the board of directors.”

According to the report, between Feb. 18 and March 19 of this year, Alvarez-Concepcion accepted an additional $1,000 in kickback payments.

In total, she is believed to have accepted $20,910 in “undisclosed kickback payments,” authorities said.

According to the arrest report, Alvarez-Concepcion was located Thursday afternoon in the parking lot of the condominium community and was taken into custody.

Detectives said she provided them with a “self-serving” statement, in which she “admitted to accepting kickback payments while acting in her position as an on-site manager.”

“This arrest reflects our commitment to protecting residents and holding accountable those who exploit positions of trust, and we will continue to aggressively combat association fraud in our community,” Sheriff Rosie Cordero-Stutz said in a statement.

As of Friday morning, Alvarez-Concepcion was being held at the Turner Guilford Knight Correctional Center. Online jail records listed her bond as “to be set.”
