During the late 1980’s, Mr. Alber began his international career by setting up an Import/Export Company in the Philippines.  Poor quality of manufactured goods caused Mr. Alber to look at foreign countries closer to home, and in 1992 he set up a 55,000 s.ft. Facility in Tijuana Mexico to produce office chairs.  He grew the company from $0 to over $10 million a year in sales by the second year with over 220 employees.  The company was bought out by its main customer providing a 300% return to his investors in just 15 months.  Mr. Alber agreed to stay on in a five year contract to manage operations.  In total, Mr. Alber lived in Mexico for 7 years while managing the day to day operations of the plant and became acutely aware and accustomed to the ways of doing business in foreign countries, especially Latin American Countries.

In 2007 Mr. Alber moved to the Dominican Republic to head up a project for a Dominican Company whereby he designed and manufactured the interior finish package for a 330’ floating Casino Ship.  The project was completed in 2009 and Mr. Alber then moved back to the U.S. and formed a Yacht Sales Company called WME Luxury Yachts.  Mr. Alber is the Co-Founder and Managing Partner of this Company with offices in Santo Domingo and Fort Lauderdale Florida.

Juan Bastilla

Juan Bautista Portorreal

Juan hails from the Dominican Republic, and could swim before he could walk. He supported his family by fishing and catching lobsters while snorkeling and selling his catch. He also spent some time working with the Santo Domingo Search and Rescue team free diving in the rivers around the city. He was always intrigued by the shipwrecks he saw and jumped at the chance to join the team and get trained to dive.

Juan joined ARS/GME in 2011 and immediately got his Open Water Diver. He quicklyfollowed that up with Advanced, Rescue Diver Dive Master and his Emergency First Response Provider specialty. Juan has extensive experience recovering artifacts and properly chipping
artifacts from the calcium matrix found in the DR.

Juan now has extensive experience with underwater metal detectors and probably has more time operating a hand-held magnetometer than anyone. He is also an excellent small to mid-size boat captain and has countless hours operating a small outboard tender.
