Psychiatrist at 1020 Prospect St, Suite 415B, La Jolla, CA 92037, sharing the suite with Koshkarian Haig A MD — two psychiatrists co-tenanting one Prospect St office in the Village core, steps from La Jolla Cove and the Gallery Row district. Dr. Calvin Colarusso has no Google reviews. The 1020 Prospect building is one of only two Prospect St addresses with mental health listings — Brain Spectrum Neuropsychology occupies 888 Prospect — making Suite 415B the corridor's sole location offering ongoing psychiatric medication management. The co-tenancy may indicate a partnership, a shared-office cost arrangement, or an overlapping schedule where two prescribers serve different patient panels from one suite. Applied Neuropsychology Institute on Pearl St — Dr. Spencer Wetter's UCSD/SDSU-trained neuropsychological evaluation practice — sits two blocks south, providing the diagnostic testing that Prospect St prescribers refer to when patients need formal cognitive assessment.
