Searching for insurance agencies in Centennial returns a great many offices that are not in Centennial. The city was incorporated in 2001 out of unincorporated Arapahoe County, and its boundaries were drawn around existing subdivisions rather than around the postal grid, so the 80112, 80121, 80122 and 80015 ZIP codes it shares run straight through Greenwood Village, Englewood, Littleton and Aurora. An agency on East Euclid Drive and an agency on East Briarwood Avenue can both print "CO 80112" on a business card while sitting in two different municipalities. Every listing on this page was checked against a street address, not a ZIP code.
The second thing this page does is label each office honestly. An independent agency holds appointments with many carriers and can move your policy between them at renewal; a captive agent — State Farm, Allstate, Farmers, American Family — represents one carrier and cannot shop the market on your behalf, however good the service. The National Association of Insurance Commissioners draws exactly this line, and it is the single most useful fact a shopper can know before making the first phone call. Both models are legitimate. Neither is described here as something it is not.
That distinction carries unusual weight along the Front Range. Colorado's hail and wildfire losses have pushed carriers to re-underwrite whole books of homeowners business, and the legislature has responded with statutory coverage floors — HB22-1111 set minimum additional living expense terms after a declared fire disaster. When one carrier tightens its appetite, an independent has somewhere to move you and a captive does not. We screened eleven Centennial-addressed agencies for this ranking and recommend five.
How We Evaluated Centennial Insurance Agencies
The Top 5 Insurance Agencies in Centennial
2026 Rankings · Centennial, Arapahoe County
Avalue Insurance
Avalue publishes something almost no agency in this category publishes: the actual list of carriers it is appointed with. Seventeen are named on its own site, among them Travelers, Chubb, The Hartford, Nationwide, Safeco, Progressive, Liberty Mutual, Auto-Owners, CNA and Pinnacol. That single page is worth more to a shopper than any quantity of marketing language about choice, because it lets you check before you call whether the agency can even reach the carrier you have in mind.
The office is genuinely in Centennial. The Colorado Secretary of State records Avalue Insurance Inc as a corporation in Good Standing, formed 1 March 2010, with its principal address at 7700 E Arapahoe Rd, Ste 330, Centennial — which matches the address and the 2010 founding date the company states on its own site. The Better Business Bureau grades the business A+, though it is not a BBB-accredited business. Nationwide's own agent locator lists the agency at the same suite, which is a carrier appointment on record.
Personal lines run to auto, home, life and umbrella; the commercial side covers contractors, restaurants, garage, cyber, professional liability and workers' compensation. Sarah Lampard is listed as president on both the agency's site and the BBB profile.
Insurance Group of Denver
The name says Denver; the office is in Centennial, and has been at the same Holly Circle address for two decades. The Colorado Secretary of State records Insurance Group of Denver in Good Standing, formed 22 March 2006, with its principal address at 6909 S Holly Cir, Ste 360, Centennial — the same suite published on the agency's contact page. Dan Mahoney is named as principal on the Better Business Bureau profile, which grades the business A+ without accreditation.
It is an independent agency and says so plainly: it is not tied to any one carrier and quotes across several. The book is unusually broad for a small office — auto, motorcycle, classic car, boat, ATV, RV, homeowners, renters, condo, landlord, flood, earthquake and umbrella on the personal side, and business owners policies, commercial property, general liability, commercial auto, workers' compensation and surety bonds on the commercial side. Liberty Mutual's agent locator lists the agency in Centennial, confirming at least one carrier appointment independently of the agency's own claims.
One caveat worth knowing: the BBB profile still carries an older South Syracuse Street address in Denver and a phone number the agency no longer publishes. The current details are the ones on its own site, and those are the ones listed here.
Preferred Choice Insurance Agency
Preferred Choice is the strongest commercial option on this list, and it holds one credential none of the others do: Pinnacol Assurance lists it in the carrier's own agency directory with a Top Agent 2026 designation. Pinnacol is Colorado's largest workers' compensation carrier, and an award issued by a carrier to an agency is a harder credential to manufacture than a self-reported statistic — it is published on the carrier's site, not the agency's.
The Colorado Secretary of State records Preferred Choice Insurance Agency Inc in Good Standing, formed 4 June 2012, with its principal address at 6767 S Spruce St, Ste 250, Centennial. The agency describes itself as veteran-owned and locally operated, and names Mike Sarris, Ken Clark and Mariselle Cruz on its team page, with a separate Spanish-language phone line published alongside the main number.
The commercial list is specific rather than generic — auto dealers, contractors, farm and ranch, liquor liability, restaurants, landlord liability, errors and omissions, cyber and group health — which usually indicates real underwriting relationships behind it rather than a catch-all page. Personal lines cover auto, home, renters, classic car, motorcycle, RV, boat and umbrella. It is an independent agency and is listed as such in the Trusted Choice directory of independent agents. Unlike Avalue, it does not name its carriers publicly, which is why it sits third.
Sean Slater — State Farm
This is a captive office and the ranking should be read in that light. Sean Slater represents State Farm and only State Farm; he cannot quote you a second carrier, and if State Farm's appetite for your roof or your ZIP code changes, the conversation ends there rather than moving to another market. That is the defining limitation of the captive model and it is why an office with the strongest individual credentials on this page sits fourth rather than first.
Those credentials are genuinely the strongest here. State Farm publishes his licence numbers on its own corporate site — Colorado CO-424843, plus Utah, Arizona and Wyoming — which is the only published producer licence number we located for any agency in this ranking. He has been an agent since 1990, holds the CLU, ChFC and RICP designations, and his agency page states a team with roughly eighty years of combined experience. The Colorado Secretary of State records Sean Slater Insurance Agency, Inc. in Good Standing, formed 5 June 2007, at the Arapahoe Road suite published by both his own site and statefarm.com.
Review volume is the largest of any office on this list: 4.8 out of 5 across 125 reviews on Birdeye. The book covers auto, home, condo, renters, personal articles, life, health, Medicare supplement, pet and small business, and the office also fronts State Farm's banking and investment products — services the independents on this page do not offer. Service in English, Spanish and French is advertised.
Inszone Insurance
The Centennial office carries the longest accreditation record in this ranking: the Better Business Bureau grades it A+ and has accredited it at the Briarwood Avenue address since 20 December 2004, under the alternate business name The Insurance Place, Inc. That is a two-decade record filed against the specific Centennial location rather than a corporate profile, which is what makes it usable evidence.
One thing to know before you call, and it is disclosed rather than hidden: this is a branch of Inszone Insurance Services, a national agency group headquartered in Rancho Cordova, California, which acquired the long-standing local practice. The Colorado Secretary of State records InsZone Insurance Services LLC in Good Standing as a registered entity with a California principal address. The agency operates on the independent model and states it has the freedom to shop the market, so the market access is real — but readers specifically seeking an owner-operated local firm should weigh the ownership.
The Centennial team is named individually on the location page, which is more transparency than most branch offices offer, and the office is one of the few in this ranking with a dedicated employee-benefits bench alongside personal and commercial lines. It does not publish its carrier list, and no producer licence number appears on the site.
Frequently Asked Questions
What is the difference between an independent insurance agent and a captive agent?
The National Association of Insurance Commissioners defines the difference simply: an independent agent may sell policies from many different companies, while a captive agent sells insurance for only one company. Both are licensed producers and both are paid a commission by the insurer. The practical consequence at renewal is what matters. If your carrier raises the premium or decides it no longer wants your roof, an independent can move the policy to another appointed carrier without you starting over; a captive office cannot. The Insurance Information Institute adds a further distinction that affects service continuity: with an independent agency, the agent rather than the insurer legally owns access to policy renewals. A broker is a third category — a broker represents you rather than an insurer, and may charge a fee for doing so. None of these models is inherently better. Knowing which one you are talking to before you call is the point.
How do I check that a Centennial insurance agent is licensed in Colorado?
Insurance producers in Colorado are licensed by the Division of Insurance, which sits inside the Department of Regulatory Agencies (DORA), and not by the Division of Professions and Occupations that licenses trades and health professions. That distinction matters because the two use different lookup systems. Producer licences are searchable through the NAIC's State Based Systems Licensee Lookup, which returns licence number, National Producer Number, status, expiry date and lines of authority. The NAIC also directs consumers to its Consumer Information Source and to the state insurance department directly, which is the route to take if a name does not resolve. Ask the agent for the licensed entity name and the licence number before you search — agencies frequently trade under a name that differs from the corporation on the licence, and searching the marketing name alone will often return nothing.
Is a Centennial address the same as a Denver or Greenwood Village address?
No, and the ZIP codes will not tell you the difference. Centennial was incorporated in 2001 from unincorporated Arapahoe County, and its boundaries follow existing subdivision lines rather than postal boundaries. The result is that 80112, 80121, 80122 and 80015 are shared with Greenwood Village, Englewood, Littleton and Aurora, and a great many agencies marketing themselves for Centennial searches are physically in a neighbouring municipality. This is not usually deceptive — postal service areas simply do not align with city limits — but it does mean a ZIP code is not proof of a local office. If a local office matters to you, check the street address against the city boundary, or ask directly whether the office you would visit is the one answering the phone. Every agency on this page was verified to a street address inside the Centennial city limits.
What are Colorado's minimum auto insurance requirements?
The Colorado Division of Insurance sets the state's mandatory minimum liability limits at 25/50/15 — $25,000 for bodily injury to any one person, $50,000 for bodily injury per accident, and $15,000 for property damage to another party. Those are statutory floors for legal operation of a vehicle, not a recommendation. A single at-fault collision involving a late-model vehicle can exhaust a $15,000 property damage limit on its own, and medical costs from a serious injury will exceed $25,000 without difficulty. Uninsured and underinsured motorist coverage is not part of the mandatory minimum in Colorado but must be offered to you, and declining it must be done in writing. Any agent on this page can explain the trade-offs; this publication does not give coverage advice and does not quote premiums.
Why does Colorado homeowners insurance get harder to place every year?
Hail and wildfire. The Front Range sits in one of the most severe convective storm corridors in the country, and repeated catastrophe years have pushed carriers to re-underwrite entire books of Colorado homeowners business — tightening roof age rules, moving to actual-cash-value roof settlements, raising wind and hail deductibles to a percentage of dwelling value, and in some cases withdrawing from parts of the state. The legislature has responded with statutory floors: House Bill 22-1111, effective August 2022, established minimum coverage requirements including additional living expense terms for total losses in a governor-declared fire disaster. The practical effect for a Centennial homeowner is that renewal terms change more often than they used to, and reading the declarations page each year is no longer optional. It is also the clearest argument for an independent agency, which has somewhere to place the policy when one carrier's appetite changes.

Our Recommendation
If you want to know what you are actually being shopped across, start with Avalue Insurance — it is the only agency in Centennial we found that publishes its full carrier list, which turns a marketing claim into something you can check before you dial. For a business owner, and particularly one carrying workers' compensation, Preferred Choice Insurance Agency's Top Agent designation in Pinnacol's own directory is the most substantive third-party credential on this page. Insurance Group of Denver is the steadiest generalist: two decades at one Centennial address and a book that spans personal, specialty vehicle and commercial lines.
Sean Slater's State Farm office holds the strongest individual credentials here — a published Colorado producer licence, CLU, ChFC and RICP, and an agent appointment dating to 1990 — and it is ranked fourth only because a captive office cannot move your policy to a second carrier. If you already want State Farm, it is the most credentialed way to buy it in Centennial.
Before you sign anything, ask for the licensed entity name and the Colorado producer licence number, and check them yourself in the NAIC State Based Systems Licensee Lookup. Ask which carriers the office is actually appointed with, not how many it claims access to. And ask what happens at renewal if the carrier non-renews you — the answer to that question is the whole difference between the two business models on this page.
