Attorney Clients and their clients have used his expert witness and consultation services on cases involving value diminution and/or construction cost estimation to real property due to construction defects, adverse conditions (internal and external to the property like site subsidence to the former and nuisance claims to the latter) and first party insurance claims; and expert witness or consultation services where the legal questions pertain to governmental compliance and regulatory issues surrounding residential real estate appraisal and/or construction, residential real estate tax issues, and issues in real estate finance (primarily residential income producing property), financial institutions, including USPAP Appraisal Regulations per FIRREA Title XI & Dodd-Frank Title XIV Appraisal Independence and appraiser malpractice stemming from the two.  The current climate in litigation where the diminution in value and/or remediation cost makes up the part or all of the prayed for damages makes retrospective valuations in the past much more prevalent.  It takes a very experienced expert to handle these one of a kind assignments, especially where the date of value is way back in time, i.e. the distant past.  Each assignment is unique and complex in their own right due to the amount of time that has passed, regardless of the complexity of the property type.  In many cases, our independent, supportable analysis has allowed clients to settle cases without going to court.

Attorneys especially appreciate working with an expert who can provide clear, enlightening testimony that is technically accurate and scientifically supportable.
