Miltoniopsis Species & Hybrids – Dennis Olivas

Tuesday, February 12th – Doors Open at 6:30PM & Meeting Begins at 7:00PM

Dennis Olivas 2018Dennis Olivas was born on the island of Kauai, Hawaii. As a lad, he helped his mom and aunt grow their orchids and got hooked. He joined the Future Farmers of America, and his project was raising and selling these beautiful and exotic plants. In 1980 he moved to the mainland and swore off the orchid family; but not for long as he went to Rod McLellan’s Acres of Orchids’ in South San Francisco. From there his whole life became one downward spiral. First, he fills his home with upwards of 6,000 plants. Later he leased a greenhouse space for his ever-burgeoning orchid collection. Glutton for punishment, his collection grew, overflowing the 3,000 sq. ft. greenhouse in Half Moon Bay.

Martin Orenstein

Dennis was President for the Peninsula Orchid Society, San Francisco Orchid Society, Diablo View Orchid Society and the Santa Cruz Orchid Society. He is an accredited judge of the American Orchid Society. Dennis belongs to over 14 orchid societies and tries to assist them whenever possible.
