About Monica

Monica  Callis

Monica Callis

Monica Callis does not just sell homes. She builds wealth, protects legacies, and moves families into their next chapter with the kind of precision most agents cannot offer. As the Broker and Owner of Callis & Co Realty, LLC, Monica has established herself as one of the most trusted and well-credentialed real estate professionals serving Houston’s Harris, Brazoria, and Galveston Counties.

With an MBA in Finance from Texas A&M University and a designation portfolio that includes the Accredited Buyer’s Representative (ABR®), Military Relocation Professional (MRP®), Certified Luxury Home Marketing Specialist (CLHMS), and Real Estate Negotiation Expert (RENE®), Monica brings a level of strategic sophistication to every transaction that her clients feel from the very first conversation. Whether you are purchasing a luxury estate, building new construction from the ground up, relocating your family to Houston for a corporate transfer, or navigating a probate or estate sale, Monica is the advisor who sees the full picture and protects every detail within it.

Monica’s path to real estate was not paved with shortcuts. A teen mother from Galveston County who graduated on time, earned her MBA, and spent seventeen years in corporate America at a Fortune 500 company before being laid off, Monica learned early that the only security worth having is the kind you build yourself. That layoff did not break her. It activated her. She launched a successful daycare business in San Antonio, then relocated to Houston to care for her aging parents, and stepped into real estate with the same fire she has carried her entire life.

The results spoke for themselves. Monica earned Rookie of the Year at a major brokerage within her first three months in sales, graduated from the Texas REALTOR® Leadership Program (TRLP), and was recognized by the Houston Association of REALTORS® as one of the Top 20 Under 40 Houston REALTORS®. She then did what leaders do: she opened her own brokerage, Callis & Co Realty, and built a firm rooted in excellence, integrity, and a wealth-first philosophy.

Monica is a recognized authority in Houston’s master-planned communities, guiding buyers through the entire new construction process from lot selection and floor plan customization to builder negotiations and final walkthrough. Her priority neighborhoods include Del Bello Lakes, Pomona, Meridiana, Sienna, Valencia, Shadow Creek Ranch, and Harvest Green, among others. With her MRP® designation and a deep understanding of what relocating professionals and their families need, she also delivers a seamless, high-touch corporate relocation experience, handling the complexities so her clients can focus on the transition.

Monica brings a rare combination of financial acumen, legal awareness, and compassion to probate and estate sales. She understands that these transactions are not just about property. They are about protecting what a family has built. Her approach integrates legacy-planning tools and careful guidance through what is often an emotionally complex process. As a Certified Luxury Home Marketing Specialist, she serves discerning buyers and sellers who expect a higher standard, delivering the white-glove experience that luxury transactions demand.

Monica believes that every real estate transaction should be a wealth-building event, not just a closing. Her MBA in Finance is not a decoration on her wall. It is the lens through which she evaluates every deal, ensuring her clients are not just buying a home but making a strategic financial decision. Combined with her background as a tax strategist, Monica offers a level of holistic financial awareness that most agents simply do not possess.

Her clients describe her as direct, strategic, and fiercely committed. She is the advisor who tells you the truth, shows you the numbers, and then positions you to win. She is not interested in being the most popular agent in Houston. She is interested in being the most effective one.

Whether you are building your first home, selling a luxury property, relocating to the Greater Houston area, or managing an estate sale, Monica Callis is the strategic partner who will protect your investment and position you for long-term success. This is not just real estate. This is legacy work.

"As first-time homebuyers, my husband and I were so nervous and unsure about the whole process, but working with Monica changed everything. From the very beginning, she was patient, knowledgeable, and incredibly supportive. Starting with the initial phone call she explained every step in a way that made sense and made us feel confident that we were choosing the right person to go on this journey with. What I appreciated most was how Monica never rushed or pressured us. She truly took the time to understand what we wanted and made us feel like finding the right home was just as important to her as it was to us. Her communication was amazing—she checked in often, answered every question quickly, and guided us through every detail with so much care. Thanks to Monica’s guidance and dedication, we ended up with a home we absolutely love. She turned something that could have been stressful into a smooth, exciting, and memorable experience. If you’re a first-time buyer—or any buyer—I cannot recommend Monica enough. She is truly exceptional, and we are so grateful for everything she did for us."

She truly works for her clients like she’s the one buying the home. If you’re considering a new construction home in Cypress or the Houston area, call Monica first.

"As a first-time homebuyer in Texas City, TX, I had no idea what to expect but working with Monica Callis was the best decision I could’ve made. From day one, Monica went above and beyond to make this process as smooth as possible. She’s not just any Realtor she’s a fighter. Monica negotiated with the builder and fought tooth and nail to make sure I could use my homebuyer incentive with a different lender that worked better for me. Most agents would’ve backed down, but Monica stood her ground and protected my best interests every step of the way. Buying a home can be overwhelming, but Monica did everything she could to relieve my stress and keep me focused on the goal. She explained everything clearly, was always available to answer my questions, and made me feel confident in every decision. If you’re looking for the best Realtor in Texas City, especially as a first-time homebuyer, Monica Callis is the one you want in your corner. She’s professional, relentless, and truly cares about her clients. I’m grateful for her and highly recommend her to anyone buying or selling in the area!"

"Where do I begin? Monica was truly a Godsend for me. We are transplants in TX, and when I say I wouldn't be a homeowner without her, that's exactly what I mean! I can be a lot - with all my questions and needing to understand every little detail, but Monica and her team were patient and understanding, coaching me through every step. This is a dream turned reality and at the end of the day, I'm so glad it was Monica crossing that finish line with me! She's my realtor for life, thank you, Monica, Corey and Shawn!"
