About JSM Development

For the founders of JSM, property development is more than a job; it's a family tradition. It started back in 1935 when the family patriarch, Lyon Hartman first went into construction with his brothers. Nearly 40 years later, sons Jeff, Steve and Mike Hartman continued the family legacy, joining various real estate development ventures to form JSM Apartments, JSM Commercial and JSM Development Services.
