"It was such a pleasure to work with Klaus. His knowledge in guiding me through all the stages of preparing and getting the house ready to place on market was invaluable. Klaus had an excellent crew of people to help stage and photo the houses and property. He made himself available when ever I needed, if I had questions, he had answers. I followed his lead and the property sold very quickly and for the price I was hoping for. I would recommend Klaus to who ever is looking for an agent that would make their selling of their home easy and rewarding."

"We have known Klaus for over 20 years. He is trustworthy, knowledgeable and a very straight shooter. When we decided to sell our Short-Term Rental Condo in Kihei we naturally reached out to Klaus. He helped us get our condo ready and showed our condo even though it was being used as a short-term rental throughout most of this process. With his guidance our unit sold at the highest price of any unit in our building to date. Klaus also is helping us complete the purchase of a house in Kihei using the 1031 funds from the condo. We are currently in escrow and are so grateful to Klaus for his patience in helping us locate a house we really are truly excited about. We highly recommend Klaus for any of your real estate needs."

"I can highly recommend Klaus Simmer as a real estate agent in Maui Hawaii. A long distance purchase is not necessarily easy or fast. We have worked with Klaus for over two years looking for a particular type of property. Both on island and in California he kept us informed as properties became available. As a long time resident he knows the area in Kula and adjacent areas very well. His knowledge and friendships gave us insights into the local geography, sunbelts and grow areas for farming, of particular interest to us. His experience in the bid process was extremely helpful. In our case he advised if we really liked a property we should bid on it and even if our offer was not accepted we should stay active in the process in case the initial accepted offer fell through. Then we still had a chance to acquire it - and that is exactly what happened. He also provided us with very valuable information on financing plus a trusted mortgage network that made the deal go through smoothly. It has been a pleasure to work with him. "

"I would absolutely agree with all the other reviews on this site for Klaus. Our particular situation was that we had a unique, beautiful, ocean view property in a remote location, with significant maintenance issues, to be sold by me living in the UK. I was able to visit twice and met with Klaus. As Covid struck I could no longer visit. Klaus had a fantastic knowledge of the local area and was able to locate and facilitate professionals to deal with among other issues, cleaning the property, and tackling the encroaching jungle, to allow the house to present itself in the best light. Klaus was available 24/7 and his advice was always good - he had a solution to every hurdle that presented itself. I personally have never had such a level of service selling a property. And to top it he is a great guy."

★★★★★
"I sold my home with Klaus just as the COVID pandemic was ramping up. It’s already a stressful endeavor to sell a home, let alone in such unprecedented times. I felt I had a knowledgeable, wise guide to take me through the process. Even in times of great uncertainty, Klaus was rock-solid, on-task and unwaivering from our original (pre-COVID) goal to have a great home sale. I found him to be highly attentive to detail, have excellent follow through and communication. His demeanor very professional yet personable; his responsiveness was thoughtful and always very quick. Klaus approached the entire experience with a gracious tenacity, yet cued off of me every step of the way, being patient and compassionate for my process through it all. The word that I would use, above all others, for Klaus is INTEGRITY. This is of supreme importance to me, and he did not falter. I never, not once, questioned that I wasn’t in good hands or that the experience could have been better."

★★★★★
"We selected Klaus because of his excellent reviews and experience, and he truly delivered exceptional service! He is extremely knowledgeable about the island, it’s neighborhoods and local vibe, and a real pleasure to work with. Very helpful in explaining the buying/selling process, contracts and even willing to go line-by-line through the paperwork with us. When we had questions about anything, Klaus responded promptly same day—very professional and straight forward. He also balanced well being our real estate “guide” and “advisor” when needed, offering us solid advice when we asked him. Ultimately, Klaus helped my wife and I find our perfect island home only after about two weeks of looking, and he had great recommendations for excellent lenders and home inspectors! We would trust Klaus to handle any of our family or friends buying/selling needs—highly recommend!!" - Terri

★★★★★
"Klaus was amazing in helping us to sell our home. He was 100% there in every aspect of the process...offering his expertise and sharing with us what our options were at every step; from listing our home, preparing for the caravan and going live with our listing, negotiating the price, moving through the inspection process and finalizing all the paper work in escrow. He was always there to answer questions and responded immediately to any concerns we had or information we needed. He was a valuable resource with the right contacts for jobs we needed done, and in the rare moment he did not have the answers we sought, he had the contacts and resources to get those answers, and our needs met in a very timely manner. He was easy to work with, and always considerate in his interactions with us. Klaus helped us sell our house in just over a month from listing to closing of escrow. We are thrilled and would highly recommend Klaus to be your realtor! He is first rate in every regard!"

★★★★★
"Klaus Simmer performed awesome for us. We fully endorse him for residential re-sales and raw land purchases. He did a “above and beyond the call of duty” job for us. Although we have vacationed on Maui for decades, we were not knowledgeable about neighborhoods, prices and Maui real estate nuances. Klaus did an excellent job of educating us and assisting us in finding exactly the right property (2) for us. We fell in love with a incredible view home lot. We consulted Klaus. He took the time to understand what we wanted. He then pointed out a much more desirable lot for the same money. It took 10 seconds of standing on the Klaus recommended lot to fall in love with it and abandon our first love. We would have saved a lot of time by going to Klaus first. Klaus did a great job of educating us on and guiding us through the acquisition process. His negotiation skills and results were impressive. We are very pleased with our purchase and Klaus’ services. With the job done, Klaus made us aware of an opportunity on a “not for sale” lot adjacent to our new home site. Through his longstanding island relationships he introduced us to the owner from whom we then acquired the adjacent lot that enhanced our newly acquired home site multiple times. Bottom line, Mr. Klaus Simmer’s services were essential to us acquiring our Maui dream. He did it with professionalism, great customer service and the Aloha Spirit. He made the process easy, fun and got us great terms. Thank you Klaus! We’ll forever be grateful for your help." - John

About Klaus

Imagine the feeling of having someone by your side who truly understands Maui—not just as a place, but as a living, breathing experience. Klaus’s story is one of passion and dedication, beginning in 1980 when a love for windsurfing drew him from Germany to Maui’s shores. He wasn’t just part of the island’s windsurfing history—he helped shape it. Competing worldwide on the World Cup circuit and creating award-winning boards, Klaus gained deep respect not only for his skills as an athlete but for his innovations as a designer. When the time came to retire from competition in his late twenties, he turned his energy to building Simmer Style with his brother, transforming the local sailmaking company into a globally recognized brand in surf wear and windsurfing equipment.


For over 40 years, Klaus has lived and thrived on Maui’s North Shore and Upcountry. With a life spent in the wind and surf, he has developed an almost intuitive understanding of the island’s microclimates. His clients find comfort in knowing they have an advisor who truly knows every detail of these areas. Klaus’s decades of on-the-water experience translate into a unique, local perspective, helping guide clients through the intricacies of Maui’s real estate market with confidence.


Working with Klaus, you’ll notice his genuine and direct approach. There’s no pretense, no unnecessary hype—just a clear, focused dedication to serving your best interests. He combines big-picture awareness with meticulous attention to detail, using his wealth of experience to make sure you’re supported at every step. His calm, low-key demeanor provides a sense of stability and trust, making the process feel effortless and secure.


Rooted in a rich cultural background, Klaus grew up in an academic family between Germany and Southern California. Fluent in German and French, he carries a cosmopolitan awareness that enriches his interactions. His passion extends beyond real estate: meditation, cycling, skiing, and a lifelong love of music make him a well-rounded, grounded advisor. This blend of global perspective and deep local knowledge makes Klaus the consummate insider—a trusted guide who brings expertise and heartfelt dedication to his clients, with a sincere love for Maui and its people.
