About Appraisal Firewall.

Our Mission

To always provide superior mortgage technology to the financial services industry

Appraisal Firewall is the story of a software company dedicated to providing relationship-based services to the mortgage industry for more than 25 years.
From our company’s inception in 1989, our focus has been to promote relationships between service providers and financial institutions.

Appraisal Firewall was developed in direct response to HVCC so that lenders could still work with their local appraisers without going through a management company. The Dodd-Frank Act replaced HVCC and Appraisal Firewall has continued to help lenders of all sizes cope with the ever-changing regulatory landscape.

Today, millions of appraisals go through Appraisal Firewall in a safe, compliant environment that encourages local relationships. We will continue to develop the technology to further enhance everyone’s lending experience while minimizing the challenges posed by the changing regulatory environment.

Dave Black President & Ceo

Dave Black is a pioneer in the financial technology and services industry. In the mid 1980’s Mr. Black developed financial information systems for several industries and municipalities, including the credit reporting industry, automating mortgage credit reporting for a number of repository bureau affiliates. A visionary in the credit reporting business, Mr. Black helped evolve the industry from earlier DOS days to the current secure online SaaS world.

In the late 1990s, Mr. Black turned to other mortgage services to utilize SaaS to streamline processes. He spearheaded the popularity of secure, cloud-based computing for the financial services industry with the bundled services platform concept, the Appraisal Management Software (AMS) concept in Appraisal Firewall in 2007, the automation of consumer tax return verifications (4506-T forms), and instant, paperless consumer lending pre-qualifications.

Dave is a tireless worker and thinker, constantly researching new concepts and styles of implementation for SharperLending LLC, the company behind Appraisal Firewall. He enjoys time with family, traveling both on his Harley Davidson and internationally, and the Costa Rica coastline.

Tiffany Saraceno
Sales Manager

Tiffany Saraceno joined the Appraisal Firewall team after 7 years in title and escrow sales. In 2011, she made a career switch to mortgage software. Her ability to build lasting relationships, understand where the appraisal industry is headed, plus her expansive knowledge of technology has been an asset to the SharperLending and Appraisal Firewall brands. She integrates product enhancement requests from customers with a well rounded view of appraisal needs to make sure system functionality continues to be all it should be.

In her spare time (she will say “what spare time?”) Tiffany has 2 children. She and her husband own a family-run business. They have built or remodeled a home every couple years for the past 11 years. She loves to garden, and has an orchard at her home where she loves to dote on fruits, veggies, kids, and on her 4 rescued dogs.

Danielle Walker
Product Manager

Despite her apparent youth, Danielle boasts a 10+ year tenure with SharperLending, starting with the company in 2006, and was present for the inception of Appraisal Firewall. Because she basically grew up within the walls of SharperLending, she has a breadth and depth of knowledge of its systems. She has worked on every product under the company at one point or another and now focuses her time on managing the development and growth of Appraisal Firewall, or as she so lovingly refers to it, her “baby.” She takes the helm in leading the company in bold, unexplored directions with product development, system integrations and really cool feature enhancements. She keeps projects in-line and on time for release into the mainstream market, all while wrangling tangent-seeking developers and using acronyms like API and SQL.

If you can ever get her away from her desk, Danielle enjoys traveling to faraway lands, binging Netflix shows and telling bad jokes in her spare time. She also loves food, whether it’s eating food, cooking food or even just talking about food.

Laura Henderson Burger
Customer Service Manager

After a decade of collecting a variety of multitasking and people organizing skills, first as a personal assistant and then as a cardiac scheduler, Laura jumped at the opportunity to join the Appraisal Firewall team in 2013. Not only did this speak to her passion for problem solving, but also her desire to not need to know CPR for a living. In 2016 Laura became the Customer Service Supervisor. She loves working with the team to provide the best possible service to our clients as well as constantly collaborating to enhance Appraisal Firewall.

Outside of the office, Laura likes to spend time with her husband Nick and their two cats Señor and Winry. They enjoy traveling, spending time at the family cabin and going to concerts & movies.
