Meet The Team

Martha Montiel-Lewis

Team Lead | Affiliate Broker

If there is one word to describe Martha Montiel-Lewis, it's passionate—passionate about her work, passionate about the area she serves, and passionate about forming genuine relationships with her clients.

Having grown up in a military family, Martha knows what it’s like to move around. Though born in Panama to two Nicaraguan parents, she was primarily raised in Germany. After moving stateside when she was in high school, she went on to earn a B.A. from Cumberland University and an M.A. from Belmont University.  Martha spent a decade working on award-winning real estate teams, where she collaborated with some of Nashville’s most prominent developers. Martha played a large part in forming one of Nashville’s most famous metropolitan areas, as her company helped to pioneer the now-iconic Gulch by building the area’s first residential high-rise development. Through these experiences, Martha forged valuable relationships she still utilizes today. Specializing in selling new developments, Martha works with her connections to ensure quality at all stages, staying involved in every step of the construction process. She also served as a key member of Compass Development’s first sales team in Nashville.

In addition to developments, Martha’s other area of expertise is assisting families moving to Nashville’s urban core and its surrounding areas. Setting out to redefine Nashville’s city living, Martha is passionate about helping families realize the benefits of living in the heart of the action—from the walkability and culture, to the excellent school systems and award-winning greenways. It's easy to fall in to love with Nashville, but it's her comprehensive knowledge of each neighborhood that allows Martha to confidently find her clients the right house.

Prioritizing authentic and empathetic connections above all else, she thrives on learning what ignited passion in her clients and helps to bring them to life in a home. Clients appreciate this honesty, loyalty, and understanding, as well as her contagious energy. Martha treats her clients like family, so it’s no surprise that she has garnered a strong referral business. Beyond word-of-mouth, Martha has the numbers to prove her premier status. She is consistently ranked in the top 5% of Nashville realtors, holds both the GUILD™ recognition and Certified Luxury Home Marketing Specialist™ designation from The Institute for Luxury Home Marketing, and most recently, Martha earned the Diamond Award from the Greater Nashville Realtors Association.

Martha enjoys being active in her free time, spending time outdoors, and traveling with her husband and two children. She also has a love for philanthropy and female empowerment, having been named to Nashville’s 40 Under 40 list for founding a nonprofit that creates jobs for women in Haiti. This passion fueled her career as a REALTOR with Compass, a company with values closely linked to her own. It's her passion for close-knit communities that keeps her connecting with neighbors day after day, fully committed to the responsible growth and sustainability of Nashville.
