Small businesses of all types, but I love to work with technology, professional services, wholesale/distribution, manufacturing, and restaurants.
Sales Highlights
I get the most satisfaction from closing the challenging transactions.  I recently sold a specialty business that the Seller owned and operated for over 30 years.  Ready to retire, we marketed his business, and met with a great response.  Every possible pitfall happened on this deal:  a dishonest Buyer vastly misrepresented himself, we discovered during due diligence that a long time employee was embezzling, and the final Buyer discovered during financing an unknown bank lien on his home!  And through all of that, we overcame each obstacle and matched the business to the ideal Buyer, who assumed the Seller’s operation with great success.

Professional Bio }
I returned to my passion and career roots in 2015, when I partnered with Sean Edelstein to fuel the growth of BottomLine Business Brokers.  I have marketed and sold a variety of businesses, ranging from restaurants and construction to professional services and technology firms.  I use my business acumen, passion for small business ownership, work ethic, and attention to detail to help Buyers and Sellers successfully complete their transactions.
I founded my first company in the mid-‘90s, an IT systems integrator with clients ranging from small businesses to the Fortune 500.  That company was purchased by a fund rolling up tech firms; this was my first exposure to business transactions.

Since then, I have continued in business leadership in a variety of roles.  I participated in a $60M fundraising round and led the technology teams who created an energy usage monitoring platform for U.S.-based food and beverage manufacturers.  I then joined a technology services firm and, in addition to my other duties there, executed the rigorous process of preparing for a public company acquisition.  I also led the creation of business automation and GPS door-to-door delivery tracking software, which has been used to track well over 15 million doorstep deliveries nationwide!   All this while a partner in owning and operating a collection of Southern California coin-operated laundromats.

While I have held a variety of roles during my career, it’s really small business ownership that is in my blood.  I am the son of two entrepreneurs, and growing up, I was immersed in the everyday experiences of small business owners.  Little did I know how strongly that this upbringing combined with my passion for technology would shape my career!
