Dave was a professor of materials science and engineering at UCLA for 25 years, taking early retirement in 1992. He and his students did research on the high-temperature corrosion of metals and alloys, primarily oxidation and sulfidation studies. This work resulted in over 140 publications, two of which concerned minerals (The Light-Induced- Alteration of Realgar, Amer. Mineralogist, 77, 1266, (1992) and Cobaltoan Calcites and Dolomites from Katanga, Min. Record, 30, 269 (1999)). He also wrote a book, The Metallurgy of Zirconium. He also edited an international journal, Oxidation of Metals, for 40 years.

He started collecting in 1989 while on a trip to Brazil for collaborative research. He became a dealer in 1991 after having become a "mineral aficionado" while having discretionary income as a single person. He met Liz in 1992 and married in 1993, moving to Tucson in that year. He and Liz have been doing many shows each year, including Tucson (Convention Center), Denver (Merchandise Mart), Costa Mesa, Pomona (now Pasadena), Bisbee, Phoenix, and some small club shows.

His outside interests include Tournament Bridge (Sapphire Life master, nearing 5000 master points) and master's track and field. He won the national decathlon championship in 1987 (55-59 year group), two indoor national pentathlon championships, 2013 discus national championship (80-84 year group), 2013 World Master championships, Porto Allegre, Brazil silver medal (hammer throw), bronze medal high jump, 2015 hammer throw and weight throw national championships, and 2016 Masters World Championships, Perth, Australia (85-89 year group) gold medal weight throw and javelin, silver medal discus, bronze medal shot put, hammer throw and throwing pentathlon.

Dave has four adult children, Lisa, Karen, Todd and Olivia, of whom he is very proud.


Liz has a BA in music from Carlow College in Pittsburgh, and an M.Ed in counseling from University of Pittsburgh. She began her career as a music teacher, and then moved into various educational counseling positions including high school and the University of Maryland. She worked for Westinghouse Corporation for 10 years, as a management development specialist and a Human Resources Manager for KFWB radio in Los Angeles. Following 4 years of management at both St. Joseph's Hospital in Burbank and UCLA Medical Center, she decided to pursue a 30 year dream. After 7 years of hard work and study, she accomplished her PhD in Clinical Psychology from Pacifica Graduate Institute. As a licensed clinical psychologist, she now maintains a private practice in Tucson, specializing in grief work, addictions, women's issues, and trauma resolution. She is also on staff at Sierra Tucson Psychiatric Hospital, Desert Star Recovery and Sabino Recovery.

Liz has traveled to many parts of the world, including a 3-week trek through the Himalayas in 1984. She ran and completed the LA Marathon, and has recently published an article based on her dissertation: When her mother dies: An adult daughter's depth perspective. She started playing the harp in 2004 and plays at a local hospice and various memorial services.

Chief Cleaner

Tara: a very conversational (but limited vocabulary) black and white also rescued from the humane society. She likes to follow us around and is in charge of quality control (inspection).

Nikki: a rescue doggie who has the longest, waggiest tail and the fastest tongue in the West. Everything is "finger-licking" good, but she'll still protect our minerals.

Felina: an affectionate calico rescued from the humane society who handles our cleaning when not busy waiting for lizards to come into the fenced-in dog area.
