Abbi Lathrop Martz

Summit Sotheby's International Realty


Abbi has an extensive understanding of Park City and Deer Valley luxury resort real estate. Having spent many years with one of the Nation’s top real estate teams in Park City as well as representing a variety of developments and property types; Abbi knows what it takes to meet investment and lifestyle goals for both buyers and sellers. Her warmth, insight, work ethic, integrity and professionalism are well known and respected by clients and colleagues alike.

Abbi began her career in Real Estate in 2005 when she first moved to Park City for a position as a summer intern. She fell in love with the ease and charm of Park City living and wanted to share the small but vibrant mountain town with others. It didn’t take long for her to realize Real Estate was what she was supposed to do, and Park City was the perfect town for her.

For years she worked alongside four of the best agents in the country. She was able to hone her sales, marketing, and negotiating skills with buyers and sellers, and provide valuable market research and strategies for the listing teams at the St. Regis Deer Valley, Vintage on the Strand, Last Sun at the Cove, Bannerwood, Nakoma, The Belles at Empire Pass, and Stein Eriksen Residences.

In 2014, Abbi joined Summit Sotheby’s International Realty, and has since successfully represented buyers and sellers throughout Park City. She also became a major contributor as a sales associate with the Montage Residences Deer Valley sales team from 2015 to 2017. She represented the highest priced condominium sold in Park City and Deer Valley in 2015, and was awarded Level-1 Professional Achievement from the Park City Board of Realtors in 2016.

Born and raised in the White Mountains of New Hampshire, Abbi comes from a family with a skiing legacy. She spent her formative years on the ski slopes and playing in the wilderness at her family’s rustic cabin on Lake Richardson in Maine. She attended a ski academy in Vermont to focus on ski racing, and was a competitive alpine ski racer on an international level from ages 16 to 23. She received her Bachelor of Arts degree in Business and History from Colby College in Maine, where she also became a six-time Division 1 NCAA All-American and was the NCAA National Alpine Skiing Champion her senior year.

Always active and energetic, she enjoys alpine and cross-country skiing, mountain biking, hiking, running, yoga, and camping, as well as spending time with family and friends. She and husband John, who grew up in Park City, are proud parents to their 1-year old daughter Elsie. They enjoy taking her on many outdoor adventures and are excited for her to get out on skis this winter!

Abbi offers a thorough and personalized approach and cares deeply about helping clients make sound decisions when it comes to their real estate purchase or sale. She listens well, is experienced, knowledgeable, detail-oriented, forward thinking, driven, and dependable. Abbi’s passion and dedication to everything she does, in conjunction with her love of skiing and deep appreciation for what Park City offers throughout the year, make her a superb match for a lifelong commitment to Park City real estate.

I see Abbi as my most trusted real estate partner and much more than an awesome broker. She is everything you would want to represent you in a luxury home transaction: highly professional, always ethical, exceptionally hard working, incredibly responsive and her knowledge of the Park City market is deep and thorough. She also has an extensive network of colleagues and friends in the area so she immediately adds value to any question you might have even if it's outside of her responsibility representing you in a sale or purchase. She has been my partner for 3 purchases and 3 sales of high-end real estate in Park City and she is absolutely top notch. I cannot recommend her highly enough. Look no further. She is amazing!

Thank you for getting this done in a way that worked for everyone and also all of the communication and thinking through best paths to get from A to B. Super appreciated!


Abbi and Bill, thank you so much for everything you did for us in this process, making it the smoothest real estate transaction ever. You guys are truly amazing and, quite frankly, the best agents we have ever worked with. The service, care, and attention to detail that you provided is second to none. We are thrilled with the house and even more excited to have you in our lives.

The process and ‘journey’ we experienced with Bill Ligety and Abbi Martz was so exceptionally wonderful, that we give them our highest praise. Our quest began in a ‘hot market’, with limited inventory. Abbi and Bill ensured a nice representation for BOTH of our requirements, but also included a sampling of other property types. Bill and Abbi took our desire to purchase a property in our selected market to possibilities beyond what was available on the market. Through their deep understanding of the community and Bill’s extensive relations, they were able to cultivate interest from sellers that did not have properties on the market or even thinking of selling. Their intimate knowledge of each property’s history, owners, situation, etc., was a unique Bill and Abbi team highlight. They diligently and painstakingly worked through remediation notes for removing contingencies and securing fair credit/adjustments. They advocated, strongly, on behalf of us as their clients. We felt that we were all part of one team, and that Bill and Abbi truly cared about our interest, potentially even at the expense of losing out a commission. We are deeply grateful to Bill and Abbi for guiding us to a new community, and a new chapter in our lives.

Cyrus and Roseann

Abbi and Bill are a dynamic duo with all of the complementary personal and professional skills that spell success. From the first call to the hand shaking at closing, and throughout every step of the process. They were thoughtful, prepared, courteous and comprehensively organized with every facet of our experience. They gave my wife and me confidence that they could meet our goals and objectives. Not only did they - they far exceeded them!

Michael and Leslie

I am very, very appreciative that you found this house for me, with all it’s twists and turns of already having an offer when we started, and I couldn’t be happier to be here! Thank you for your hard and diligent work in helping me find the perfect house.


Bill Ligety and Abbi Martz are a results oriented, professional team. They represented us in selling vacant land in Deer Valley. With their comprehensive knowledge of Deer Valley real estate, their strong connections in the community, and wide outreach through Sotheby’s International Realty, they were highly effective in all aspects of the sale. They knew just what would be successful in the current market and kept us apprised every step of the way.

Tom and Marilyn

In one word, Abbi can be described as tremendous. She was able to find us a great property in what seemed to be an impossible market for buyers, and on a very tight timeline. She is highly competent, professional, knowledgeable, and a pleasure to work with. I would recommend Abbi for any of your real estate needs in the Park City area.


My wife and I were introduced to Bill and Abbi just prior to a planned New Years Eve ski trip to Deer Valley. We were interested in exploring properties during our trip, but we didn’t leave ourselves a great deal of time to do so. Fortunately, we had Bill and Abbi on our side. Not only did they work within our tight time frame to schedule every property we wished to see, but they provided a great deal of expertise, data, and research to help us make a sound decision. Within 30 days of meeting them for the first time, we closed on our property. Bill and Abbi were organized, thoughtful, available, and professional throughout the entire experience. They truly made it a smooth experience for us from start to finish. We highly recommend Bill and Abbi for any purchase or sale you may be contemplating.

Jeff and Sunshine

Abbi is a complete rockstar. She was my agent on two of many real estate transactions in the last few years. These two transactions were an absolute dream - fair prices paid / sold, very little stress, and strong negotiating by Abbi. This is all despite some nuance about the properties involved, having a home occupied by renters with at-risk children right as COVID hit, me changing listing dates on her several times, etc. Abbi handled it all with grace, went over the top to help me in preparing / taking care of the house while I was out of state (she even mowed my lawn and weeded when it got out of control and I couldn't find a service), and generally made me less stressed and more confident at every point in the process. On this last sale, I feel like I did maybe less than one hour of work in the entire process, I never even made the 4 hour drive to check on the house because Abbi had it covered from start to finish. I would never even consider using anyone but Abbi on a Utah transaction at this point.

Bill and Abbi made purchasing a ski home long distance easy and enjoyable. We flew in from Wisconsin for two days of touring homes and they had everything lined up as well as beautifully prepared booklets of the places we toured, and maps of the area. We had time for second looks on the properties we were interested in. Everything flowed smoothly and we made excellent use of our limited time. Bill and Abbi have extensive ties to and knowledge of the Upper Deer Valley area in which we were interested, and we found that helpful when choosing the place that was right for us. They are also extremely detail oriented and made closing go very smoothly. We are busy professionals with four children and we wanted some "hand-holding." They introduced us to contractors that were needed for contingency repairs and reminded us of every deadline. They provided a list of contacts and click-throughs to city municipalities, cable, alarm companies, property managers, etc. Absolutely everything we needed to do in order to purchase a home was spelled out and made simple for us. Four months after closing, when the snow was gone so that roof repair could be finished, they reminded us about it (we'd already forgotten about it). Throughout the process, Bill and Abbi were always accessible by phone call, text, or email, and they are delightful to work with. We couldn't be happier with our new home and we highly recommend Bill Ligety and Abbi Martz.

Peter and Cari

Amazing to work with and as first time home buyers, Abbi took the time to walk us through all the steps and help us through the negotiation process with a short timeline!

Sarah S.

After showing us so many fabulous homes in upper Deer Valley over the past year you offered to contact the sellers of a property which was not on the market and within days we were under contract! Amazing. Then, despite the COVID19 hurdles you both delivered exemplary service with your attention to detail and response times which allowed us to navigate the process of buying our home without a hiccup. The negotiations, coordination of inspections, appraisals, estimates on repairs, transferring utility services, HOA agreements, etc. were all handled seamlessly, professionally and the best part, cheerfully! You two are special people. We felt reassured throughout the process with your knowledge of the area and concern for our happiness.

Carolyn and Mike

I wish we had started our sale process with Bill and Abbi. They worked hard, they kept in touch and were consummate professionals. When we sold our house and had a very small window to close they arranged and supervised our packing and moving. We couldn’t have been more pleased with their services. We highly recommend Bill and Abbi.


You are an absolute delight and consummate professional. Thank you for your patience, good nature and guidance.


My husband and I had a condo in Park City that we needed to sell. The transaction had a lot of moving parts. We were cross country, were doing a reverse 1031 exchange, had purchased another condo, needed to get our condo on the market ASAP, but while we were getting our home on the market we moved our furniture out and had our old place staged. As a REALTOR in North Carolina, I knew we needed someone with attention to detail, knew the market, understood the real estate business and communicated. Bill and Abbi placed our condo on the market, astutely communicated with us on what we needed to do from our end, worked with the flowing marketing details of new furniture, pictures, etc., perfectly. They got our condo sold quickly, for top dollar, and the attention to detail and communication thru the contract to closing phase was exceptional. I highly recommend Bill Ligety and Abbi Martz for your real estate transaction. They are true professionals!

Michelle P.

Abbi and Bill, thank you for your terrific work. You were able to close the sale quickly in less than three months at a price significantly higher than any previous sale in our neighborhood. You’ll always have our highest recommendation and we can’t thank you enough for all you accomplished for us.

Steve and Marcia

Last spring Bill and Abbi Martz helped us sell our home and purchase another home nearby in upper Deer Valley. We were delighted with their services and professionalism. Their knowledge of the upper Deer Valley marketplace is superb. The research and presentations of market comps were spot on and easy to understand. Their suggestions and help with staging and presentation of the property made for a readily marketable presentation. Their use of excellent photography and first class brochures as outstanding. Their open houses and use of existing client base made for a fast sale. Bill and Abbi handled negotiations with the buyer regarding price and terms and many other details made the selling experience easy for us. And their continued follow thru on the due diligence, inspections, and numerous other details thru and after closing was a true blessing for us.

Gary and Debbi

Abbi and Bill, we took a good look at a hand full of your “top-producer” competitors and are delighted that we selected you. Your price and market analysis were spot-on. Your marketing program was great and, to our pleasant surprise, produced a near full price buyer in a little over a month. You two were great in every step of the process, many thanks.

Fred and Sue

The two of you did an outstanding job. The attention to detail, foresight through the acquisition/negotiation process and timely communication led to the purchase of a great family home. In the event we buy and/or sell another home in the area, you are our first and only call.

Mike and Karen

Abbi was a perfect realtor for us. We were first time buyers and needed lots of help navigating a tricky negotiation and purchase process. Abbi was consistently honest and straightforward with us, often making note of challenges that we hadn't yet thought of, which (we think) is a rare quality for a realtor.

She was able to bring us to properties and show us how to look and what questions to ask. She had great knowledge of the Park City market and area and really helped us to see the pros and cons of buying a condo vs. house and of Park City's various neighborhoods.

We never felt that Abbi was leading us in a direction that we weren't ready for and always felt that she was being 100% honest with us. Abbi is energetic, bright and easy to work with. She knew when to take the reigns and be our leader and when to step back and allow us to discuss independently. We honestly aren't sure that we would have bought a home in Park City without her and will recommend her to other buyers with no hesitation. Lastly, we will plan to use her if and when we decide to sell our home.

Ramsay H.

Great agent! She has a wonderful personality and is so knowledgeable on the market in Park City. Her dedication to her clients is super, and she goes above and beyond! She helped us stage our home which made it perfect for showings. We would use her again in a heartbeat and would recommend her to anyone we know that is looking for the best agent in Park City.
