Who We Are

The Modern Pledge

The evolution of the personal property appraisal process has been ever-changing over the years.  Modern Appraisal Services exists to bring today’s technology to the forefront of the personal property appraising business. Our investment in technology means faster turn-around times and lower costs for our clients.  

My name is Derek Slavensky and I am the owner of Modern Appraisal Services. I have been an entrepreneur all my life operating eBay businesses, and multiple companies ranging from S-corps, LLC’s, and Non-profits.  I have brought these experiences and lessons in business and have applied them to a career in personal property appraising.  


We offer personalized and tailored services for a wide range of clientele. My preferred approach is to take the time to get to know each client, their history and their objectives so I can exceed their expectations.  This approach enables me to truly enjoy my work and get to know some great people.

No matter the reason for the appraisal, we treat each assignment individually so you get the attention you deserve.  I’d be honored to help you with your appraisal needs.
