About Advent Valuation Advisors
Advent has been providing business valuation and intangible asset appraisal, litigation support, forensic accounting and business consulting services to clients throughout the US for over 25 years.
Founded in 1991 by William Quackenbush, a recognized leader in the valuation community, Advent is conveniently located in Newburgh, New York. Newburgh is located in the breathtaking Hudson Valley, minutes from New York Stewart International Airport and less than two hours from New York City and Hartford, Connecticut.
Our clientele include individuals, attorneys, privately held companies, estates, company shareholders/partners/members, banking professionals, and non-profit organizations.
Advent has prepared more than 1,000 valuations in over 300 industries. Our valuation expertise encompasses not only businesses, but tangible and intangible asset valuations as well. In addition to our valuation experience, our professionals possess extensive experience in litigation support, forensic accounting, and expert witness testimony.
Unlike many practitioners, our team performs valuation, litigation support, and forensic accounting work full-time, not as an add-on service. Each Advent professional is a specialist in their field, possessing advanced degrees and professional credentials including the ASA, MCBA, BCA, ABAR, CVA, ABV, CPA, CIRA, MAFF, CFF, or CFE designations.
Advent provides individualized and objective attention to our clients. But equally important, we are known for the quality of our work product. In addition, our team is well informed about current valuation topics including IRS and court matters, valuation theory application, discount rate development, DLOC’s and DLOM’s, and pass-through entity tax concerns. Our reputation for excellence is evidenced when opposing counsel subsequently engages Advent’s services.
Our professionals are “thought leaders,” serving in professional association leadership roles, speaking at professional conferences, authoring articles and providing continuing education to accountants, attorneys and appraisers.
Advent is an affiliate of RBT CPAs LLP, the Hudson Valley’s largest CPA firm. RBT has been named among the 100 Best Companies to Work For in New York State since 2016 by the Best Companies Group, and ranked among Accounting Today’s Top 100 Accounting Firms to Work For in 2016, 2017 and 2018. Through our RBT affiliation, we are members of the RSM US Alliance, a nationwide association of independently owned local and regional accounting, consulting, and service firms. Another affiliate, Spectrum Pension and Compensation, Inc., provides pension and employee benefit advisory services. Advent’s alliances allow us, through our affiliates, to provide clients with the expertise, quality, and services they would expect from a much larger firm.
