Client Testimonials

“Jan and Katie are the best! I would happily work with them again. They made the sale process much less stressful and much more pleasant than it could have been.” ~ Chris Trounson
“We Were Very Happy We Used Jan As Our Real Estate Agent. Jan helped us buy our home in Sierra Madre. She was very patient and understanding of our specific needs. She showed us properties as soon as they came on the market, and was very helpful throughout the transaction. She brought paperwork to the house so we didn’t have to leave. Everything went smoothly from start to finish. Even when we had trouble making the loan deadline, she came up with helpful ideas. She even brought us sturdy moving boxes to help with the move. We were very happy we used Jan as our real estate agent.” ~ Nancy & Gary Dorn
“The most caring team in the biz. If you’re in The San Gabriel Valley, please don’t hesitate! They will take care of all your real estate needs. Love them.” ~ Devon Fenimore
“I highly recommend Judy, Katie & Jan. I have used their services many times over the years and have never been disappointed. When my mother passed away this year I had to sell her home. Even though I lived in Oregon they took care of everything for me long distance. They make the process easy!” ~ Nancy Carlin
“Having bought and sold many properties over the years I must say this was the smoothest, easiest sale yet. Jan Greteman made sure I had everything I needed. She and Katie ensured that I got the very best price, the best assistance for my move and wonderful support throughout the process.” ~ Suellyn Ellerbe
“Enthusiastically Recommend Jan Greteman!!!! Dear Prospective Buyer or Seller, After serving 11 years in the U.S. Army, we relocated our family from Colorado to Southern California earlier this year. For months prior to our move, we diligently searched for our next home. Although we’ve lived in multiple locations throughout our time in the service, the market in the greater Los Angeles area was unique and steeped with challenges. Despite months of searching online, we couldn’t close on a property. We were feeling the pressure! After two weeks in an extended stay hotel with our four kids and two dogs, we were feeling discouraged. That all changed when we contacted Jan. She was ready to help at the drop of hat and quickly closed the deal to get us into a wonderful place. Jan is truly a caring person who was an enormous help and took total care of us throughout the process. The quality that stood out most was Jan’s personal touch. Although we just met her, she treated our family like lifelong friends. Moreover, she had the confidence and professionalism of a seasoned REALTOR®. Los Angeles has a unique market when it comes to real estate, whether you’re looking for a rental or to purchase, and need someone with the experience to make things happen. I would like to take this opportunity to enthusiastically recommend Jan Greteman as a real estate agent for any individual or family looking for their next home.” ~ Brian & Stephanie Murdock
“Very Knowledgeable and NEW to Southern California! Jan performed a wonderful job of helping us to find the right home. She listened to our goals, provided all the information we needed, and was on top of the details at every step in the process. Beyond the house search and purchase, Jan provided very useful information about our new location such as cultural opportunities and local businesses. Jan also introduced us to a reliable contractor, for moderate changes to the house, and dependable trades people. Jan’s warm personality and positive outlook made buying our home a pleasure. Jan’s help went above and beyond our expectations of a REALTOR® and we are very grateful to her!” ~ George S.
“Jan is family now! We’ve been looking for a house in Sierra Madre for a little over 3 years. The market is small and our wishes were very specific... we drove most local real estate agents crazy ;-) Jan was patient and listened closely. We were in contact every now and then, depending on what the market had to offer. After 3 years, we were tired of looking; tired of all the open houses... Then Jan called and said “you gotta look at this house.” A few weeks later we moved into our beautiful new house with the most amazing view over the San Gabriel Valley! I was 30 weeks pregnant when we moved in. Jan always offered her help and said she would be there when I need her. We have family in the area but not in town so we asked her if she could watch our toddler when we have to go to the birth center... One night I called her, she answered her phone “do you need me to come?” and was there not even 5 minutes later. Very unplanned, we had a home birth (our baby came within 1 hour). Jan was there for our daughter’s first cry, was the first one to see her. Jan, you are family to us. Thank you for everything!” ~ Birgit and Scott Haas
“We recently worked with Jan Greteman on two transactions. An unexpected purchase of a wonderful Altadena fixer with additional lots, then the sale of our rental home. Jan was great working with us on the purchase, open to our ideas to get the purchase closed quickly for all parties. And we couldn't have been happier with our sale, which closed in just 12 days after less than a week on the market! She also was extremely helpful with staging, and recommendations for minor repairs. We would definitely work with Jan again.” ~ Alicia Barclay
“We recently worked with Jan and Katie to sell our home. Because of their experience and professionalism, it sold very quickly and at much more than the asking price. Jan and Katie are truly exceptional in every way, and we highly recommend them to everyone who is buying or selling real estate!” ~ Geoffrey Middlebrook
“Katie (and, more recently, Jan) have helped us with at least 7 real estate transactions, which included located highly desirable rental properties, purchasing 2 beautiful residences, and profitably selling 3 homes. They have been unfailingly attentive to our needs and desires, and their professional knowledge of the local market is extraordinary. Above all, they are patient, honest, kind, and deeply humane. I can't imagine working with any other realtor.” ~ Caroline McManus
“Our experience with Jan and Kate and the Webb- Martin Group truly was top notch. We are self admittedly picky and demanding and my expectations we not only met but exceeded. We had a very fast paced turnaround of buying our new home and then prepping the old house to sell in a short window of time. The team responded to every text, email, call and endless list of questions with thorough and seasoned advice. We sold our house in a matter of days MUCH over asking and are now settled and in love with our new home in Sierra Madre. I will go as far as to say for a process that is typically stressful, we had a lot of FUN!” ~ Elizabeth Pritchett
“When you need the best, you go to Webb Martin Group! We have exclusively used them to buy and sell our homes and every time they’ve gone above and beyond. Their knowledge and expertise is what keeps them several notches above anyone else is the business. They listen, advise and tell it to you straight. You are dealing with the best of the best! Webb Martin Group is and will continue to be our first choice. I cannot recommend them enough!” ~ Carrie and Carston Bell
“Dear Jan, We just wanted to thank you for your part in the successful completion of the sale of the property on Alegria Street in Sierra Madre, owned by the Moss Trusts. Your attention to detail, your dedication to a positive outcome, and your thoughtfulness in dealing with Ed as trustee and Burt as bookkeeper for the Moss Trusts is well recognized by both of them. In addition, I would like to personally thank you for your efficiency and pleasant personality in dealing with me as I handled the computer connections and other peripheral parts of the business dealings. If we ever have the need for realty services in the future, we would look forward to the possibility of working with you again.” ~ Edward & Diana Dickstein
“This team knows the San Gabriel Valley (and in our case the Sierra Madre) real estate market very well. Their smart advice was spot on. Listing our home with this team was a great choice as they made the entire process worry-free and efficient for us. Such a pleasure to work with these professional and caring people. Would work with them again in a heartbeat!” ~ Karen Wales
“It is my pleasure to recommend Jan Greteman as an outstanding real estate agent. She represented me as a buyer’s agent in the summer and fall of 2015, and during that time remained attuned to the preferences and limitations that I placed on our housing search. She also kept me apprised of potential listings the moment they came on the market, including the one that eventually became my home. The home I did purchase was in a highly desired neighborhood and had a number of attractive features that made it a very competitive bidding process. The house received multiple offers within days of the listing, and with Jan’s guidance I was able to present an offer and subsequent counter-offer that appealed to the seller and won over the other beds, and yet still fit will within my budget. As a first time homebuyer, the entire proccess was entirely new to me, and Jan did an excellent job of keeping me informed of the process and ensuring that everything went smoothly. When there were potential delays in our contingencies, Jan made multiple phone calls on my behalf to the seller’s agent and my loan officers to work it out in my favor. And she always made it very convenient to sign all of the neccessary paperwork by completing it all either via email or by driving to meet me, such that there was surprisingly minimal impact on my schedule. Finally, as I prepared to move in, she even helped with arranging utilities, and went so far as to wait at the house for technicians to turn on the utilities while I was at work, such that the home was truly move-in ready on our closing day. In summary, Jan was a pleasure to work with, and I highly recommend her in your own home search, particularly if you are a first time home buyer as I was.” ~ Aaron Robison
“Over a 36 year period We have bought two homes and sold two homes with Judy Webb-Martin. Working with Katie Orth and Jan Greteman on the last three has been a pleasure. Each time - in three completely different housing markets - it was an excellent experience, personally and professionally. They listened, they advised and when a firm guidance was needed they gave it. They know what they are doing! They also know they are dealing with your home and respect that. They are not one size fits all realtors - and this last sale, we simply turned over to them knowing we were in good hands. Highly recommend them.” ~ Se Doyle
“Our experience using Jan as our realtor was fantastic, there really isn't enough we could say to do her justice. She gave us great advice and helped us through the buying process the whole way through. Buying during COVID was tough and Jan helped us get to the finish line with a very difficult bank. Her experience and savvy was also extremely helpful in a competitive market. Other agents we had worked with in the past left us disappointed, constantly feeling like we were being unreasonable or being a nuisance when asking questions. When we met Jan we realized that's not how it should be, especially when making such a big decision - she truly cared about and wanted the best for us. We wholeheartedly recommend Jan and Katie to anyone in the market, it was truly a pleasure working with them!” ~ Natasha Peterson
“We spent years looking for our “forever” home in Sierra Madre before meeting Jan. As soon as I met Jan, I knew I wanted to work with her. We really liked her straightforward, honest style. She is completely authentic and follows through on her word. She is never pushy, but ready to work hard and take action when you are ready. She is extremely knowledgeable about the area and is a natural at making connections in the community. We were under a tremendous amount of stress during the purchase of our home and subsequent renovation and she handled it like a professional. What has impressed us the most about Jan is that now, a year after buying our home, she is still there for us. We have never experienced that before with past realtors. She helps us with referrals for projects around the house, invites us to community events, and stops by with pumpkins or other treats for the kids. It’s nice to have a realtor that cares about you after the deal closes and who you can call a friend when it is all said and done.” ~ Nicole Cozby
“Extremely pleased! They definitely had our best interest in mind at all times. Worked very hard and we highly recommend them!” ~ Gale Knckelbein
