Dartmouth Economics '26

Economics Major and Entrepreneurial Problem Solver.

I graduated from Dartmouth in June 2026 with a degree in economics and a concentration in finance. I co-founded Pest OS, an AI phone system for pest and wildlife control operators, and spent the past year as a venture analyst at GHC Partners. Problem solving in dynamic, entrepreneurial environments captivates me. I work best when I can immerse myself in a problem and take ownership of the solution. Pest OS had me cold-calling owners and closing our first deals. GHC had me deep in filings, market data, and fund research. Now I'm looking forward to new opportunities and new problems to solve.

Professional

Co-Founder of Pest OS · VC Analyst at GHC Partners · Dartmouth Economics '26

I co-founded Pest OS, where we built a system that handles missed calls, books jobs, and manages the full customer lifecycle for pest and wildlife operators. We have paying customers, won the Magnuson Founder's Grant from Dartmouth, and I've pitched companies in parking lots across New Hampshire to get there.

At GHC Partners, I built the fund's LP outreach pipeline, ran investment and market analysis, spearheaded an alternative fundraising initiative, and produced macro research included across several LP reports. I took a graduate-level business strategy course at Tuck Business School where I led an activist-investor analysis of Callaway Golf, and I wrote a paper testing whether VCs actually know more than the market.

Interests & hobbies

Avid outdoorsman · Decent shot at pool · Musician

I fish, climb, and ski. I've fished across Canada, summited Mount Washington in winter, and went paragliding in Italy during study abroad. I speak Italian and lived in Rome for a term, which is where I met my Pest OS co-founder.

I'm a lifelong skier and taught skiing at the Dartmouth Skiway. I picked up billiards at school and ended up running the Billiards Club as president. At Dartmouth, I played lead guitar and harmonica in a band called Cherry Hills. We played a lot of Greek houses.

I love jumping into new things.
