About Garrison Companies
The About Us page identifies Garrison "Gary" Hassenflu as Founder and Owner of Garrison Companies. It states he has "over 25 years of commercial real estate brokerage and development experience" in the Midwest and Mountain States and has "personally developed over $140,000,000 in assets" in those areas. Before real estate, he worked as an accountant with Arthur Young Company in Kansas City from 1983 to 1984, preparing tax returns for individuals, partnerships, and corporations. From November 1984 to February 1991 he was a Sales and Development Associate with the Leo Eisenberg Company in Kansas City, handling selling, leasing, and managing of office, retail, industrial, and multi-family property. From March 1991 to November 1997 he served as Owner/Broker of Garrison Commercial in Prairie Village, KS, brokering commercial real estate and consulting on affordable-housing tax credit projects across Missouri, Kansas, Iowa, Nebraska, Oklahoma, Utah, Colorado, Kentucky, and Arkansas. In November 1997 he formed Garrison Development Company (GDC), and in April 2001 he formed Garrison Management Company (GMC) to manage the LIHTC communities GDC developed; the site states both entities "operate to the present." From 1997 to the present, the page says Hassenflu "has developed, owned, and managed over 1400 residential units in six states, represented in 18 living communities." Note: the separate Investors page states the company has generated value "since 1998," a year that does not exactly match the 1997 founding date given here; the site does not reconcile this discrepancy, so both figures are reported as published.
What Garrison Companies does
Garrison Companies is a real estate development and property management firm operating across the Mountain and Plains states, with plans to expand nationwide. The company is made up of affiliated businesses: Garrison Development (also referred to on the site as Garrison Community Development, LLC) specializes in developing, acquiring, and rehabilitating affordable multi-family housing in Kansas, Missouri, Nebraska, Colorado, Utah, and Oklahoma, targeting projects valued between $25 million and $80 million. Garrison Management Company offers management for both affordable and market-rate rental properties, including properties owned by Garrison Companies as well as select third-party properties. The firm also provides project financing, combining private and agency debt, equity, tax credits, and tax abatements to fund housing. Other services listed on the site include acquisition and historic rehabilitation of buildings into lofts (described as creating over $70 million in value), not-for-profit consulting and participation to help nonprofits expand affordable housing, and comprehensive market analysis using third-party data during the development process. The site states the company specializes in "everything from adaptive reuse of historic buildings to mixed-use developments and luxury housing." The site does not list specific service pricing, quotes, estimates, or rate cards for any of these services; anyone with a specific project or housing need is directed to contact the office directly by phone or email.

Company Mission and Development Focus
Garrison Companies describes its mission as creating "high-end luxury living communities that meet the evolving demands of lifestyle renters, millennials, and soon Gen Z, seeking premium rental options," while blending living and leisure opportunities. The Mission page states the company includes Garrison Community Development, LLC and Garrison Management Company, Inc., "operating as a unified team to construct, acquire, rehabilitate, and manage multi-family and mixed-use properties across the Plains and Mountain States with an eye toward nationwide expansion." The page frames a specific problem the company positions itself to address: "One of the Biggest Challenges in Many States Is the Shortage of Accessible Housing," arguing that communities need clean, quality rental housing for essential workers such as entry-level employees, new teachers, firefighters, police officers, and city maintenance staff, and that retaining these workers strengthens the local tax base. The site states the property management team has "over 25 years of experience" and is "dedicated to providing exceptional service for all residents." This page does not itself list pricing, hours, or specific project addresses; it links out to a project catalog (Planned Projects, Existing Mixed Income / LIHTC Properties, and Past Sampling of LIHTC/Market Rate Projects) and to Contact Us for further information.
Investment Opportunities and Financing
The Investors page states that Garrison Companies transforms neighborhoods "through new construction and the rehabilitation of under-utilized historic buildings," and says that "since 1998," the company has "generated over $140 million in value." The site describes its goal as creating projects in strong markets that deliver value while minimizing risk for investors, and says the team provides "timely quarterly reports and essential communications throughout the project lifecycle." For financing, the page lists Tax Increment Financing, C-PACE Financing, and Historic Preservation Tax Credits as tools used to assemble what the site calls "low-risk, high-return investment opportunities." It also states that project hold periods and guarantor recourse are customized to individual investor needs, ranging from "personally guaranteed construction financing with a short-term mini-perm to agency loans with competitive rates for longer holds." Garrison Companies also provides management services for properties owned by its affiliates. The site does not publish specific expected returns, fee schedules, minimum investment amounts, or the pricing terms of any individual deal; it directs interested investors to "Invest Today" and to contact the company directly (phone (913) 257-3416 or office@garrisoncompanies.com) to discuss opportunities and financing terms. No specific licenses, registrations, or securities credentials are listed on this page.
Residential Communities and Property Examples
The Residents page describes Garrison Companies as building "high-quality housing and luxury living spaces across the Midwest and Mountain States," with amenities such as swimming pools, fitness centers, outdoor kitchens, package delivery systems, and proximity to public transit, and states the company emphasizes security, sustainability, energy efficiency, and environmentally friendly construction. The Existing Mixed Income / LIHTC Properties page lists specific communities: the Manhattan Building, described as a 42-unit, age-62-plus LIHTC living community located at 320 W. Broadway, Muskogee, OK, in the historic Manhattan Construction Building, offering affordable rent for income-qualifying tenants; Maple Ridge Apartments, built in 1998, a two-story, 18-unit community located in Chadron, Nebraska (zip code 69337), near Chadron State University and the Nebraska National Forest; and Surety Apartments, whose page description (under the heading "Mill Supply Apartments") places it in Coffeyville, Kansas, on Union St. in the 67337 area, inviting visitors to check current floorplan options. The site does not publish current rental rates, deposit amounts, lease terms, or real-time unit availability for any of these communities on the pages reviewed; prospective residents are directed to contact the leasing office or Garrison Companies directly for current pricing and availability at a specific property.
