About Mary Gerwin

I have a long-term view of every client interaction--it's never a "transaction" to me, it's a long term relationship. As a result, my recommendations and advice are always guided by my clients' needs. Buying and selling homes can be exciting but also stressful, so I try to help my clients understand the process, the pros and cons of every situation, and the perspective needed to make good decisions. My business is 90% repeat clients and referrals, which is a tremendous compliment. Thanks to my long term relationships, I am ranked in the top 1000 brokers nationwide!

  • "My experience of selling through Mary Gerwin and her PorchLight Group was outstanding. I was representing an estate, and there was much I did not know about the house and the property on which it stood. Mary stepped in with great advice and guidance that helped me sell the house in the easiest and most organized way possible. Mary’s familiarity with a number of ancillary businesses that aided in preparing the house for sale, conducting the estate sale of personal property, and staging the house with attractive furniture for the sale was wonderful. We had an excellent offer under contract within a week of putting the house on the market, and the process of moving to closing could not have been easier or more efficient. I would recommend Mary and her PorchLight Group to anyone, and I will definitely engage her again in any future real estate transaction."

  • "It is with pleasure and gratitude that I share my comments on my experience with Mary Gerwin and her team at the PorchLight Group in the listing and sale of my home. I can't say enough about Mary’s professionalism, true caring nature, and extensive knowledge. She is very fair, responsive and yet firmly loyal to her clients. I have known Mary for over nine years – she helped me find and buy this same property, so when it came time to sell, I did not have to think twice who I would charge with representing my interests. Mary has got to be the most knowledgeable real estate person I’ve ever known. I found working with her a joy and felt like she was there to help me during every step of the processes. She emanates a sense of trust-worthiness that makes you feel very secure during what is without a doubt a very involved process. She is a true professional in every sense of the word and puts her clients' interests far above her own. She brings all these qualities to the table for her clients, not just in the real estate transaction, but also in the transition to their new home/community. When I purchased my home from her, she was always available with recommendations for handymen, snow removers, among other professionals. She has always come through with excellent and timely recommendations, and always made me feel like helping me was her highest priority. Mary knows the market, she negotiates strongly, anticipating problems before they can occur, and never takes her eye off the ball. Mary and the PorchLight Group are by far the best option for anyone desiring to sell or buy a property. She goes above and beyond in every phase of the sales effort: useful insights on pre-listing renovations/staging, effective showings, and proactive facilitation during the sale negotiations/due diligence. All of these tasks, whether business-related or interpersonal, were accomplished with a noticeable degree of competence, integrity, and grace. I am truly grateful!"

  • "Mary was absolutely great! She went above and beyond what any agent has done for me in the past. She’s so professional and also very understanding. I’ll never need to look for another agent in Denver."
    Tim Mulville

  • "Mary Gerwin is simply the best! We purchased our home in South Park Hill in August and could not be more thankful for her involvement. Coming from another hot market, we were terrified that our search would be endless, but we miraculously landed our first offer, in no small part due to Mary’s remarkable knowledge of the market. She is resourceful, caring, attentive, considerate, and a consummate professional. She diffused every obstacle almost instantly and removed all traces of anxiety. Mary has an endless list of on demand resources that made our purchase as smooth as possible. Thank you!!!"
    Caleb D.

  • "Years ago, I asked friends to help me find a realtor for the out-of-town family of a friend who died suddenly. I got two referrals to Mary Gerwin. Finally, I called Mary to sell my humble condo. She staged it, priced it right and a buyer signed in three days. I’d moved to a different town, so when a stealth leak grew to a tsunami, Mary remained calm. She worked with my claims adjuster, brought in her tested experts and turned a potential disaster into opportunity. The buyer, rather than backing away, delighted in making some feature choices. My insurer told me Mary’s professionalism and her expert repair crew made a big difference in meeting claim requirements. And me? I teach strategic problem solving so I stayed out of her way and watched a master at work. I can’t thank Mary enough for turning what might have been a costly and difficult situation into a speed bump for me. Mary loves what she does and she makes the management of complex problems look easy."

  • "Mary Gerwin helped us buy our house to get us ready for our move to Denver and the experience was simply outstanding. She took the time to understand exactly what we were looking for and always put our needs first. When we found the perfect house, she even helped us win out over an all-cash offer! All along the way, she had tons of helpful recommendations for both the process and all the other vendors we needed--any problem we ran into, she always had a solution ready in no time. At one point our lender told me--unprompted--"you know, Mary is simply the best in the business." I completely agree."
    Magnus von Koeller

  • "I recently had the privilege of working with PorchLight's realtor Mary Gerwin. She not only found and closed the perfect new home for my family, but Mary made the stressful period of selling my former home painless. Her professionalism and class is unmatched. The process of buying and selling a home with Mary was more than a business transaction, she genuinely was interested in my needs and made them her priority. I would recommend Mary to anyone for future real estate endeavors."
    Lisa Pearl

  • "Mary Gerwin is true professional realtor. I give her 5 stars and recommend her to anyone looking for expertise in RE transactions. She is honest, dedicated to her clients and a pleasure to work with."
    Herschel Cravitz

  • "We have to admit we were people who didn't think paying a realtor a commission to sell our house and purchase another home was practical. Mary Gerwin at PorchLight helped change that perspective completely. We watched Mary take over our neighbor's listing, market and show their house, and it sold immediately. We reached out to her and she was the consummate professional. We were worried that the peak season had passed. She reassured us and we couldn't believe the consistent helpful and informative communication, the impeccable advice, and the level of knowledge Mary brought to the table. We've watched several properties in our neighborhood languish on the market with other real estate agencies. Not our house - she had our place sold in just under two weeks. We sold our house for what we wanted and she represented us in the purchase of our ideal new home. We couldn't have done it without her. She was there to explain things every step of the way. This was not our first home purchase and we are both lawyers. We have all of the knowledge we need to navigate a real estate transaction, but we don't have the experience, the patience, or the wealth of connections in the business. Mary Gerwin has that. We will recommend her to anyone looking to sell or buy real estate. She is worth every bit of her commission and more."
    Jennifer J.

  • "Denver's real estate market is intimidating, but it feels much more manageable when you have someone you can trust in your corner. Mary Gerwin was everything I could ask for in a realtor, and more! Mary helped me understand the market, and started our work together with a Market Education Day that gave me a better feel for what was out there. Upon finding a house, she helped me write an incredibly competitive offer that ultimately won, and when there were problems with the HOA, she was a great advocate for me. The contract ultimately fell through, and Mary immediately jumped on finding me new listings to check out to find my perfect property (which I was lucky enough to find!). Mary was instrumental in helping win the bid on my new home. Throughout it all she put ME first, not the commission. I cannot recommend her enough! If you're looking for someone to help you find your dream home, look no further than Mary Gerwin - you won't be disappointed."
    Marissa P.

  • "We loved working with Mary Gerwin and the entire PorchLight team. We had put our town home on the market with another realty and it just sat there for months with very few showings. Mary and her team came in and saved the day. She got us priced right, marketed to the right audience, and under contract in 2 weeks. (And, then she sold our next door neighbor's town home a week after that!) PorchLight's marketing was by far much better than the other agency we used. They use all the digital tactics, but also don't skip the basics like great signs, beautiful brochures, open houses, and word-of-mouth. Mary Gerwin is a true partner. She went above and beyond in terms of communication and made everything as easy as possible with obtaining bids and scheduling contractors. We barely had to do anything! Mary is a straight-shooter, a true professional, and has impeccable standards. She also connects on an emotional level which is so important during the stressful decision of buying or selling a home. She'll make you feel like you are her one and only priority and that she is truly part of your team."
    Ivy Hastings

  • "We loved working with Mary. She is everything a seller could want in an agent. She's realistic. She's efficient. She's communicative. Ours was a quick relocation situation. Mary told us just what to do to improve the house, we did it, and then she handled the rest. When we turned the keys over to her to get the house sold, we had no doubts that she would deliver, and she did! Mary really made it easy to sell our house in Crestmoor."
    Matt Baline

  • "Mary found us 7 years ago when we owned a house that wasn’t selling. Her knowledge and professionalism convinced us to switch realtors and go with Mary. Since then, she has completed 4 transactions for us and should be given the official industry title of Realtor Extraordinaire. She and her group take the extra steps to ensure that you house is ready to list, recommend appropriate price points, provide sound counsel in making tough decisions, and know how to manage the other side of the transaction to make the process as smooth as possible with the highest likeliness of success. Without her work ethic and understanding of the need to often go above and beyond, it would not have been possible for us to sell a house with a tough location in a recession, purchase a house in a short sale situation, split our property into two, and maximize the value of the house we recently sold. In addition, she is an enjoyable person who my wife and I now consider a close friend."
