My name is Oliver Keller, PhD and I am a Collections Specialist at the University of Michigan in Ann Arbor, MI, USA and the owner and primary consultant of Keller Entomological Consulting LLC. Previously, I received my PhD in Entomology from the University of Florida. My background in taxonomy and systematics and my time working in natural history museum collections uniquely qualify me to provide professional appraisal of insect collections for tax deductible donations.
