Lamar Odom is expanding his business portfolio ... his newest venture aims to find affordable living for seniors in California, and he's crediting his grandmother with the assist.
The former NBA star's manager tells TMZ ... Lamar is partnering with Regency Palms Senior Living in Oxnard and Long Beach to start Odom Senior Care, which provide affordable and luxurious care for seniors.
We're told Lamar's inspiration is his 96-year-old grandmother, Florence, who now lives alone in the same Bronx apartment she's called home for a whopping 70 years.
