Mark Abissi, president and owner of the firm, upon graduating from Delaware Valley University, began his appraisal career in 1985 as an assistant appraiser with a firm in Doylestown, Pennsylvania. He was involved in several facets of valuation including financing, condemnation, estate planning, and relocation appraisal. Covering a territory that included Eastern Pennsylvania and all of New Jersey, Abissi gained experience in different markets and was soon appraising properties for multiple clients and government agencies. In 1990, Abissi moved on to an appraisal company in Warminster, Pennsylvania that focused on commercial and industrial properties, emphasizing income producing properties. Abissi performed numerous analyses on shopping centers and regional shopping malls. Abissi gained national experience and appraised numerous commercial and industrial properties throughout the United States. As ad valorem taxation was a large part of the company’s portfolio, Abissi was provided the opportunity to testify before several Assessment Appeal Boards in both Pennsylvania and New Jersey.

Mr. Abissi then joined Indian Valley Appraisal Company in 1994 and became a partner in the firm in 2001. His experience at the firm has included all aspects of real estate appraisal, including commercial, industrial, and residential. Mr. Abissi's responsibilities include appraisal review, supervision, litigation, and condemnation services.

Abissi founded the International 22q11.2 Deletion Syndrome Foundation (www.22q.org) in 1999. He also served on the boards of Peaceful Living and Ivy Hill Equestrian Center. While no longer serving on these boards, the Abissi Family is active in the community with other charitable organizations. When not appraising, Mark enjoys spending time with his wife and children, biking, and playing bass in the worship team at his church.

Anne Gorman began her foray into the field of real estate in 1984 as an administrative assistant in a local real estate appraisal company. Within a short period of time, she became an appraiser. During that time, Ms. Gorman performed relocation appraisals for several national firms covering the five county Philadelphia region.

In 1995, Ms. Gorman joined Indian Valley Appraisal Company as a residential staff appraiser. Gorman earned her undergraduate degree from Temple University during her initial years at IVAC. Assisting in the appraisal of the Hill School in Pottstown was a highlight of this time and set the stage for a switch to the commercial sector.

Gorman gained experience in all aspects of the appraisal of agricultural, commercial, industrial, and residential properties for condemnation, estate taxation, financing, and what was to become her specialty, conservation easement. Her conservation clients include many municipalities in the five-county region as well as property owners, attorneys, and private conservation groups. This basis of knowledge has served the IVAC team well as we continue to be a market leader in the appraisal of conservation easements.

When not appraising, Anne enjoys spending time with her family and friends and traveling near and far.
