Sotiris K. Kolokotronis is the Founder and President of SKK Developments, a real estate firm with a history of innovation and success in land development, home building, multifamily, and mixed-use infill development projects. Since 1987, Mr. Kolokotronis has been a principal in the development of a real estate portfolio exceeding $2.5 billion, comprising more than 11,700 residential home sites, 2,000 single-family homes, 3,000 apartments, and 660,000 square feet of commercial space in Northern California, Colorado, Nevada, and Oregon.

Having completed several notable master-planned community and home building projects, SKK shifted its focus to developing Sacramento’s urban core in the early 2000s. SKK’s residential and mixed-use projects have proven to be a catalyst for the renaissance of Midtown Sacramento. In 2001, and in partnership with local redevelopment agencies, SKK completed The Fremont Building – the first mixed-use building of its type completed in Sacramento’s urban core in over 40 years. In the past seven years, SKK has accounted for nearly 50 percent of all market-rate residential units built or under construction in Midtown Sacramento. In total, SKK has delivered over 1,500 apartments and townhomes and 55,600 square feet of retail space in Sacramento’s core valued at more than $650 million since 2018.

SKK Developments recently completed Channel 24, The Eames, The Mansion, The Eisley, The Press, H16 Apartments, Eleanor Apts., Q19 Midtown, and 20PQR Townhomes in Sacramento’s Midtown. In 2025, construction commenced on SKK’s 13C Apartments venture, 127 middle-income, studio apartments, fulfilling a need in the City of Sacramento for more workforce housing.

SKK has been selected as the development partner for Sacramento Municipal Utility District’s (SMUD) 20-acre asset, which is expected to be transformed into a mixed-use community with 900 residential units, 20,000 square feet of commercial/retail, and various regional and community amenities. Additionally, the City of Roseville chose SKK to develop the 401 Oak project site, a mixed-income building comprising 108 apartments. Finally, the City of West Sacramento awarded SKK the City’s Grand Gateway Master Plan development, a mixed-use community to include 332 apartments, a 120-key hotel, and 30,000 square feet of retail. Other shovel-ready SKK sites include Juno and ALFA Apartments, totaling 222 units and 49,000 square feet of retail. SKK Developments’ pipeline comprises 1,689 units across six sites, with development costs of nearly $768,000,000.
