He holds an MS in Marriage and Family Therapy from Nova Southeastern University and has accumulated over 13 years of clinical experience across a wide variety of populations. He specializes in providing therapy, coaching, and mediation services to members of the Effective Altruism, rationalist, and longtermist communities, addressing issues such as motivation, impact-related guilt, non-monogamous relationships, and secular approaches to grief.

He is also known online as DaystarEld, under which he writes rationalist fiction (notably "Pokemon: The Origin of Species"), produces content on epistemics and emotional intelligence, and has directed and taught at more than 20 rationality camps and workshops including SPARC, ESPR, and Atlas over seven years.
