We buy, hold, and operate rental homes — short stays and long ones — in partnership with the Glasstone Group for sourcing and management. The portfolio is small on purpose and built for the long run.

IdiogenicOsmoles

Our medical-education brand. Its first product was the Joslin Chest Atlas, an early Apple App Store hit; other titles included Tick Doctor. We did early work building the public iOS apps for MDCalc and the New England Journal of Medicine. Now live is RobotParrot, a personalized post-shift audio-lecture service for emergency-medicine residents. IdiogenicOsmoles sits alongside a small blend of other operating businesses, held under Bramble Tree Property, LLC.

Before Empire Oaks existed as a portfolio, there was Bramble Tree Estate — a wedding and events venue that hosted hundreds of ceremonies on a piece of land we still tend. The Bramble Tree name carries forward through the family operating business and daily work.
