Dominick Gambino

President, Diversified Municipal Services

As President of DMS, Dominick maintains the Certified PA Evaluator (CPE) designation and has been licensed by the PA Bureau of Professional and Occupational Affairs as a Real Estate Instructor. Dominick established Diversified Municipal Services Inc in 1999.

From 1978 through 1990, he held the position of Manager of Accounting for the Allegheny County Controller’s Office where his responsibilities included the auditing and processing of the county’s revenues and expenditures, reconciling the county’s general ledger and assisting in the preparation of the Comprehensive Annual Financial Report (CAFR).

In 1991, he held the position of Administrative Assistant to the Controller in charge of special reports and audits. The reports are highlighted in the county’s CAFRs, including a report featured on Dateline NBC. The reports detailed and corrected deficiencies in governmental systems that resulted in additional revenue and expenditure reductions for local taxing authorities and changes to county, state and federal regulations. While in this position he was instrumental in crafting the county’s bulk tax lien sale that resulted in $40 million of additional revenue for the county.

Concurrently, from 1984 to 1992, Dominick was elected to the Wilkinsburg Borough Council, elected borough and school real estate Tax Collector and was appointed to collect all Act 511 taxes. He held several board positions including member of the Board of Directors of the Wilkinsburg Development Corporation, Pennsylvania State Pension Board, the Champions Association and Treasurer of the Board of Wilk-Penn Water Authority.

From 2001 through 2003, following Sabre System’s completion of the 2001 reassessment, he returned to the county as the Manager of the Office of Property Assessments (OPA). In 2002, OPA conducted its first in-house computer assisted mass appraisal (CAMA). In 2003, OPA facilitated the conversion of 1.8 billion bits of property data to the county’s present CAMA system, including a new GIS division to digitize all parcels. Under his guidance the real estate website (www.county.pa.us) was enhanced to include an interactive GIS mapping system and a sophisticated search engine allowing for complex queries of assessment data.

From 2001 through 2003, OPA staff, in conjunction with the Appeals Board, 200,000 assessment appeals. Thirty-one OPA employees qualified for the Certified PA Evaluator (CPE) designation. In addition, Dominick initiated continuing education classes at CCAC to instruct citizens and real estate professionals about the nuances of CAMA systems. Mr. Gambino is a graduate of Duquesne University.
