Kasia is the ultimate professional. Her willingness to be available at her client's convenience, her knowledge of the market and the way she relays accurate and factual information is unparalleled. Together we have had the opportunity to assist first time homebuyers, DACA recipients and self employed borrowers with complicated financial data. Not only was she able to help them find their perfect home, she was able to get this done within 2 offers in a highly competitive market and price range. It has been my pleasure to partner with Kasia, and to get to know her as a friend. Kasia's eternal smile and positive outlook is exactly what every buyer needs, during the most stressful transaction of their lives! She will not disappoint you. If you were to write down every hope you have for the realtor that will make your dream of homeownership, or in buying your next property, they would all be fulfilled by Kasia Sullenberger.

Kasia, this is the second time you represented us in purchasing a home and you went above and beyond once again. We couldn’t have a better agent and a friend during this journey. Thank you so much for being patient with our decision making, being responsive, and when was the time, you were ready to put the offer in this competitive market. You are very knowable and professional, that’s why we were able to win over the cash offer. You are a fantastic negotiator that is always looking out for the client. We are proud that we could be the first client of Humble Bee Realty. We love our new home and are really happy to be only 30 minutes away from our favorite ski resort. You are making our dreams come true and we are lucky to know you. Thanks to the great person you are, we wish you a lot of success in Humble Bee Realty. We’re sure that your big heart and professionalism will help others to find their perfect home. Also, big shout out to Tamara from Stewart Financial for managing to close the loan in such a short time. Kasia and Tamara, you are both best people to work with. THANK YOU!!!

Kasia possesses all the best attributes you want in a realtor – a keen understanding of the Colorado market, broad experience, and a willingness to work hard start to finish. But for me, what sets her apart is her genuine drive to make dreams come true. She is as empathetic and invested as her clients. She loves her job and it resonates through her work. Kasia has guided us through the buying and selling of two homes and has earned our business for life.

Kasia helped us close on a house recently. Her knowledge of the area, and her ability to interpret what we wanted got us closed super fast. So she is wonderfully efficient. But I think her best assets were her friendliness, and honesty. Was a pleasure working with her.

As a first time buyer in the Denver Metro, all I would hear from friends and co-workers was "Be Patient, it's not a lot out there", "You're likely going to get outbid", "Hurry-up, go ahead buy this one, it's not what you really want but..." With Kasia as my Realtor I went from a vague interest in home ownership to being under contract, in about the span of a week. She is a good listener, and good judge of personality; making weeding down the options a breeze. She did a great job at negotiating the terms, and communicating with all parties. She was very knowledgable in the realty realm; whereas she saved me thousands of dollars buy recommending shopping around for, and pressing my lender to exploit lesser known savings tools. Her network of business associates and friends is top notch, which is an invaluable resource when trying to do anything from saving money to life coaching/development. For a warm personal touch, try Kasia out!

Kasia is really amazing person and realtor. We were first time home buyers, this process was very stressful for us. Kasia made sure that she knows what we really want, she was available to talk all the time, making sure that we are doing ok. She made sure we get place we love, we won against dozen offers. If you need someone to walk you through that process and be by your side she is the one.

Kasia is professional, honest and knowledgeable real estate agent. I highly recommend her services to anyone looking to buy or sell real estate.

Kasia is an amazing person and realtor. She takes such good care of her customers!!! Anyone would be more than lucky to have her as their realtor!!! 5+ stars!!!

Kasia is the BEST! I "interviewed" 10 different agents and she shinned above them all. She was so invested in my needs and wants right off the bat. She showed up very prepared for our first meeting and really listened to what I was looking for. She was quick to adapt when we bumped up against something that didn't fit my needs. She did this awesome thing where she would have me go into the house first, by myself, and get my own unaided sense of the house, to see if it felt like a fit for me or not. Her team moved swiftly, found and exercised leverage and was able to save me about $15K in closing and repair costs, etc. We were able to win the bid on the house by ensuring we could close in 15 days and actually closed in 10 days! She has continued to be a great resource and friend. Her genuine love of people and life permeates her business. I can't recommend Kasia enough!

My experience with Kasia started during the uncertain state of COVID which imposed a lot of limitations, requirements and hold ups as a result of county and state ordinances. Kasia navigated the difficult times with a high degree of professionalism coupled with knowledge of the specifics and the dynamics of the market to achieve optimal results. Her superb marketing and communication skills, excellent responsiveness, friendliness and kindness, transformed the entire process into a smooth sailing. Always ready to accommodate with a smile, Kasia exceeded my expectations not only as a highly qualified professional, but as an incredible human being with a big giving heart and never ending humanity. I highly recommend Kasia for all of your real estate buying or selling needs!

The best realtor and just amazing person in all aspects. She’s super attentive and will always do everything she can to make things work in her clients favor. I appreciate her willingness to always make herself available for showings and advice as well as her positive attitude during house hunting. Our family really appreciates you Kasia you’re amazing!

I cannot say enough good things about Kasia and her professionalism. She truly went above in beyond when selling my place by staging perfectly, coordinating cleaning, meeting with a maintenance person, and making sure every detail was taken care of. This was not the first time I have used Kasia for a real estate transaction and it will not be the last!

Throught the entire home buying process I always felt that Kasia had my best interests at heart. I never felt rushed to make a decision and everytime I asked her opinion I felt she was answering honestly. Kasia is not only incredibly knowledgeable and skilled, she is also a joy to work with. I would highly recommend working with Kasia to all of my friends and family

I highly recommend Kasia to help sell your home. She deserves more than just 5 stars! I needed to sell my home quickly and she went to work. She did an amazing job staging my home, walking me through the home selling process so I understood what to expect and did a great job negotiating with potential buyers. I can’t say enough good things about Kasia!

To Whom It May Concern My name is Andre Ray, I recently had the privilege of doing Business with Kasia, I purchased a home in Westminister, CO. that she was representing. My interactions from start to finish with her were very Pleasant. She was a person with a very high level of integrity and she always demonstrated Professionalism throughout the entire process. I would recommend her services to anyone who is in need of a noteworthy Realtor. Respectfully Submitted Andre Ray

I randomly found Kasia on a Facebook group, she was one of the only people who responded to my message about helping us possibly move from Texas to Denver! Kasia was great to work with, she is Probally the happiest, positive and patient person ever! we knew nothing about where we would want to live or even if we actually even make the move! But Kasia took us under her wing, and patiently showed us around neighbourhood after neighbourhood, educating us about everywhere, until we found the one we loved. Once we found the house she dealt with the builder for us and attended meetings we couldn’t be there for and gave us progress pictures while we were still living in another state! Would highly recommend her and she has become a friend through the whole process too!

Kasia help me sell my home for more than I originally asked, she also got 3 weeks free rent and a post occupancy agreement from buyers. She is a down to earth and honest person.

Kasia Sullenberger is the agent you are hoping for to have while buying / selling a home. Our experience with Kasia is far beyond any scale. It felt like she was truly a family, such a great personality, assisting us with her expertise, profesionalism and fantastic negotiating skills. In a very competitive real estate market these days, Kasia was able to negotiate a credit from the seller, and point out some valuable aspects of the house to even save more on a finall price . We were so impressed! She always knew what to say, what to expect, and the best part, when the emotions / stress kick in, Kasia opens your eyes and quides you through with her logical thinking and lots of knowledge. We highly recommend Kasia Sullemberger to be your real estate agent, because you will not be disappointed.

Kasia is really amazing person and realtor. We were first time home buyers, this process was very stressful for us. Kasia made sure that she knows what we really want, she was available to talk all the time, making sure that we are doing ok. She made sure we get place we love, we won against dozen offers. If you need someone to walk you through that process and be by your side she is the one.

Kasia is a great realtor. She helped me a lot to find my home and I feel very happy with it now. She also was very proffesional and kind. She always cares of her clients and makes sure that the client is satisfied with every single thing in the process of bying a house. I highly recommend her. She is very nice and a good person in which you can trust.

Kasia helped us sell our home in Elizabeth, Co. We had just purchased it just 6 months before with her help but because of our work we felt it was better to return to NM where most of our work was. She made the sale completely non stressful for us. She dealt with every aspect of the sale from showings to the closing. We moved out before she listed the home and she handled the beautiful photos and marketing, the multiple offers and negotiating the best offer for us, the contact, the inspections, the appraiser, and the title company. I really appreciate her honesty in our representation. She proved she is very knowledgeable about all Real Estate aspects

Kasia helped us sell our first home and buy our second. She was wonderful throughout the whole process, and the results speak for themselves. She is responsive, knowledgeable, and always kept our interests at the forefront. We recommend her wholeheartedly.

My husband and I worked with Kasia to purchase a second home in the Denver area. I highly recommend her to anyone. Kasia is very patient, easy to work with, knowledgeable and honest. Our situation was a bit different as we were buying this home with a reverse mortgage and it was a foreclosure. It was a Bank of America/Carrington Mortgage seller who had no sense of urgency and with a listing agent who was pretty much incompetent. It took over 2 months for them to respond to our offer correctly so we could be under contract! I believe the reverse mortgage totally confused the seller side. She was always available to us, responding to emails and calls at any hour and putting in way too much time to handle the issues that arose. The inventory for what we were looking for was very sparse. We wanted land, at least an acre and a nice home. Kasia spent a great deal of time helping us and keeping us calm through this often frustrating process and after 3 months we finally closed. We highly recommend Kasia - we will work with her again if we choose to buy another home in the future but definitely not a similar situation foreclosure!

Kasia was recomended to my husband and me by our friends. They said many good thing about her and her work. Now I know why!!! She is not only great agent, great advisor and has big knowledge about the real estate world, but also she became our great friend. No matter what time it is and how many questions you have she will always answer them and be there for you. If not her negotiation skills and knowlege of Afordable LIving Program our offer would never be picked from few others and we wouldn't be able to close on December, 24. It was the best Christmas gift! Thank you Kasia!!! We were lucky to have Kasia and we will recomend her to anybody who wants to find the home.

Truly outstanding! Kasia kept in close contact with us before we even arrived in Denver...sending us homes to view over the internet. I thought it couldn't be done in 3 days...but she helped us the best house. She was with us through the whole process. It was seamless!

We were so lucky to have Kasia as our realtor. She found us the most amazing home. She was always quick to respond, helped us find some great schools, and has great attention to detail and follow up. We highly recommend her as your next realtor. Best experience we have had with purchasing a home. Thank you Kasia for finding us the most beautiful home.

Kasia is very meticulous in every aspect of her work. She responds to questions in quick and professional manner providing extremely detailed answers. With her broad knowledge of the market and neighborhoods buying our home was a breeze. She also possesses superb negotiation skills, she got us into our home for under the asking price in a sellers market (June 2014)

Kasia was very professional in her work. She helped us throughout the buying process and gave us lots of options when it came to choosing a house we would have liked to purchase. She possessed all of the important qualities that a retalor should have; kindness, honesty, and integrity. Overall, my family and I were unbelievably fortunate to have such a knowledgeable person helping us throughout this journey.

I am absolutely fortunate to have found Kasia! Acting as a trustworthy and persistent guide and educator, she helped me take something that seemed so foreign and not possible into the realm of the real. Not only is she a woman of moral character, precision, and heart, she is passionate about helping people through the home process, whether buying or selling. This isn't just a job or a way to make money for her. She had one of those until she found this, and now makes it an art. I would NEVER use anyone else from here on out. She will be a lifetime representative for me in the real estate world.
