About Marni Kelce

### Marni Kelce: A Dedicated Real Estate Professional

Marni Kelce is a proud third-generation native of Colorado, having spent her life between the scenic landscapes of Colorado and Southern California. However, her heart firmly resides in the Mile High City. Marni embarked on her real estate career at the age of 18, later enhancing her expertise through studies at Fort Lewis College and Colorado State University.

Early in her career, Marni gained invaluable experience working as an assistant to her mother, Caron Andrews, a highly regarded real estate agent. During this time, she also managed a limousine service and co-founded CJM Enterprises, where she and her partners focused on purchasing and renovating properties.

In 2000, Marni transitioned to full-time real estate sales and established Kelce Enterprises, which she successfully operated from 2002 to 2011. Her commitment to excellence has earned her the prestigious 5280 Five Star Realtor award, recognizing her as one of the top 7% of Realtors in Denver based on customer satisfaction across ten key areas. Additionally, she holds the designation of Foreclosure Intervention Specialist (FIS).

### Marni's Approach to Real Estate

Marni's business is primarily referral-based, reflecting the strong relationships she cultivates with her clients. She continued to collaborate with her mother, who served as her assistant until her untimely passing in March 2013. Marni provides dedicated service to both buyers and sellers along the South Corridor, from Denver to Castle Rock, and prides herself on fostering genuine connections. Many of her clients not only view her as a trusted real estate advisor but also as a friend.

### Beyond Real Estate

In addition to her real estate career, Marni is passionate about wellness and runs a business focused on educating individuals about toxic-free living. She assists clients in managing various health challenges, including migraines, fibromyalgia, Crohn's disease, high blood pressure, and more.

Marni has a history as an adventure enthusiast, enjoying activities such as skydiving, paragliding, dirt biking, motorcycling, horseback riding, mountain biking, and snowboarding. A significant horse riding accident, which resulted in a compound fracture of her femur, prompted her to reflect on the fragility of life.

### Current Interests

Marni is currently engaged in shooting, tubing with her dogs, and working towards improved nutritional health. Her diverse interests and commitment to both her clients and personal well-being define her multifaceted approach to life and work.

Arapahoe County stands as one of Colorado's most dynamic real estate markets, stretching from the bustling Denver metro suburbs to the foothills communities that offer mountain access and urban convenience. With 8,125 actively licensed real estate agents serving this diverse market, the county represents a concentration of real estate expertise that reflects both the area's growth trajectory and its complex geographic diversity.

The market here defies simple categorization, encompassing everything from luxury developments in Cherry Hills Village to emerging neighborhoods in Aurora, family-friendly communities in Littleton and Englewood, and growing tech corridors around the Denver Tech Center. This variety creates unique opportunities and challenges that require deep local knowledge to navigate effectively.

Major Arapahoe County, Colorado Real Estate Markets

The Denver Tech Center area drives much of the county's high-end market activity, with Greenwood Village and portions of Centennial commanding premium prices due to corporate proximity and newer construction. Aurora, the county's largest city, presents a fascinating contrast with rapidly appreciating neighborhoods alongside established communities, while Littleton and Englewood offer more traditional suburban markets with strong school districts and historic charm.

Surprisingly, some of the county's fastest price appreciation has occurred in previously overlooked areas like Sheridan and parts of unincorporated Arapahoe County, where buyers seek affordability while maintaining Denver metro access. The foothills communities, including Columbine and Ken Caryl, continue attracting buyers willing to pay premiums for mountain views and trail access, creating micro-markets with distinct pricing dynamics.

Market Dynamics and Geographic Complexity

Arapahoe County's real estate complexity stems from its role as both a destination for tech workers and families seeking suburban amenities, plus its function as a gateway to Colorado's outdoor recreation economy. Properties near light rail stations command premiums, while areas with mountain access see seasonal fluctuations tied to Colorado's outdoor lifestyle trends.

The county's agent concentration reflects this complexity, with specialists focusing on everything from luxury estates in Cherry Hills Village to first-time buyer programs in Aurora's diverse neighborhoods. Market timing varies significantly by subarea, with some communities seeing multiple offers remain common while others have shifted toward more balanced conditions, making local expertise increasingly valuable.

Why Businesses Need Arapahoe County, Colorado Agent Contact Data

With all 8,125 active agents maintaining email contact information, Arapahoe County offers businesses unprecedented access to real estate professionals serving one of Colorado's most economically vital regions. Mortgage lenders, title companies, and home service providers can target specialists in luxury markets, new construction, or specific geographic areas, maximizing marketing efficiency in a county where agent specialization is increasingly common.

The concentration of agents also reflects the county's role in Colorado's broader economic growth, making these contacts valuable for businesses serving real estate professionals, from technology providers to continuing education companies. Given the market's sophistication and the high transaction values common throughout much of the county, building relationships with these agents represents access to a particularly influential segment of Colorado's real estate community.
