It's what I do...and how I roll!

Mary is an awesome real estate agent! I was so lucky to have found such a dedicated, honest, patient and knowledgeable real estate agent. Her wonderful personality made going through the process so much less stressful, explaining in detail step by step, always ready and available to answer any questions & concerns. More importantly, always having your best interests. I would highly recommend Mary!

Mary is knowledgeable, as she knows LV very well, professional, and reliable. She took the stress out of purchasing a home. She is also very kind and patient. Thank you Mary - we love our new home.

We worked with Mary 10 years ago when she helped us find the perfect home. 10 years later when we decided to move out of state, Mary was our first and only choice to help us sell. Her professionalism, responsiveness, integrity and knowledge is second to none. She is a delight to work with and a terrific resource when dealing with buying, selling or even considering real estate. I have recommended anyone that I know that is in the market to go to Mary if they want piece of mind and to have a great and experience working with a true professional that cares about her clients. We loved our experiences with Mary.

Since my wife and I met Mary several years ago, she has been so helpful in the navigating the purchase of homes. I highly recommend her because of her professionalism, honesty knowledge and to do what’s best for her clients. I highly recommend her to get the job done.

Mary is a realtors relator. She is passionate about her work evidenced by her patience and dedication to get her clients exactly what they are looking for. She is well versed, and knowledgable. Mary makes herself available based on her clients needs which is important if you are out of state. These are not just accolades, these are truths that speak of her work ethic, exceeded only by her charm wit and personality. We love Mary!

Mary Ulasewicz was highly recommended by our good friends. Hiring her was the best thing we could have ever done. She is very very knowledgeable about the ins and outs of buying and selling and HOAs, which we didn’t have a clue. She worked with us and our lender (who was out of state) 7 days a week for over 2 months. We would have been lost if not for her. It had been 35 years since we bought a house and didn’t know anything about the market. She made sure she brought us up to speed. Mary is very friendly and easy to work with. She wants to make sure you know what is going on. No realtor could have done more than she did to make this a good experience. We would absolutely positively recommend her to friends and family. Happy to say a friendship has evolved from this experience.

I can't say enough about my experiences with Mary. I've had two transactions with her, buying and selling a home. Both times she has all the qualities I seek, but often don't find in business. She's available, punctual, gives you a realistic view of the situation and has a ton of experience. Not to mention fun to be around. If I buy in the area again, I'll certainly be using Mary.

Thomas Halliday - Aug 14, 2020

Best agent in Las Vegas. She’ll have your back from day 1. I bought 4 houses with her and sold 2 for me too. Give her a call!

Tom & - Jun 30, 2020

Amazing! We have known Mary for 10+ years. We don't think there are enough great words to describe Mary and her expertise in realty. Besides her great personality, she cares very much about her clients, what they think and how they feel. She always goes above and beyond to make sure your experience, whether buying or selling, is a positive one. AND is everything you hope and dream it will be. We value her professionalism and opinions very much! When we thought there wasn't a chance of selling a condo of ours during this terrible time, she got the job done and in record time. Mary will always be considered a dear friend. We will never use anyone else, she is simply the best!

Mary Ulasewicz has been an especially important part of our family adventure here in Las Vegas since moving from Los Angeles in 2010. Mary helped us purchase our first home. Her knowledge of the housing market and the best neighborhoods to bring up our children gave us a destined advantage. 10 years later, the value of our first home gave us the ability to place a large down payment on a larger home in a very nice neighborhood in Las Vegas. Of course, Mary did her magic selling our house. Our home was listed on a Wednesday, and we had the offer we accepted on Friday. Mary also negotiated the price of our new house for 15K below the listed price. Mary’s professionalism, expertise and friendly manner made my wife (Debbie) and I more at peace with the whole process. Mary was always available to answer all our questions. We consider Mary a friend.

I’ve known Mary Ulasewicz for several years. I have purchased three homes and sold one home over the past four years. She is a very good listener and communicator. Mary handled my transactions beautifully – always professional and responsive. She addresses questions and issues quickly. My escrows were smooth with no hitches. I feel confident referring her to other people for their real estate needs. When you’re working with Detective Mary – you have ‘no worries’.

Sendy Lopez - Mar 02, 2020

Since the first time Mary helped me purchase my first home, I trust no one else. She listens to what her clients want, she is patient and most importantly, she is very knowledgeable and professional at what she does! I have recommended her to my friends and we all agree she’s the best!

Wendy - Mar 02, 2020

Outstanding! From start to finish Mary was by far the most helpful, committed, and professional real estate agent with whom I have ever worked. She has my highest recommendation!

Chris Witt - Mar 02, 2020

Mary has done 7 buying and selling transactions for me since 2011. Her professionalism, responsiveness and knowledge of the market is indisputable. In short, she is the best.

Richard &Grachelle - Mar 02, 2020

We went through a handful of other agents before we found Mary. We will never use anyone else. At times we felt we were teaching some of those other agents about real estate. That has never been the case with Mary. Her knowledge is quite extensive and we value her whether buying or selling. She listens to what we're trying to accomplish and then finds a way to make it happen for us.
