As Green Lake’s lead GIA-trained diamond buyer, I personally seek out the finest gemstones at the best value for our custom jewelry clients. With over 35 years of experience across jewelry retail, wholesale, and manufacturing, I bring a deep level of knowledge and credibility to the custom design process - something I take great pride in sharing with every client I meet. Those clients often tell me that what stands out most is not just my eye for stones, but the genuine care I bring to every interaction. For me, it’s an honor to be part of someone’s story through a gemstone that will be cherished for generations.

I’ve always had a passion for gemstones. Growing up in the Pacific Northwest, I was a self-proclaimed “rock hound,” spending my time collecting fossils and minerals. That childhood hobby eventually grew into a lifelong career - one that has taken me around the world in search of exceptional stones. From direct buying trips in Hong Kong, Israel, and New York, I’ve had the privilege of sourcing truly special gems for clients who appreciate quality and craftsmanship.


At Green Lake, I’ve helped assemble the largest collection of diamonds in our history and even partnered with a renowned cutter to develop a proprietary gemstone cut with a unique number of facets, made just for our studio.

Outside of the gem world, I’m an avid mountain biker - rambling the trails from Whistler to Moab whenever I can. And, true to my Seattle roots, sushi is always at the top of my dinner list.
