He works hard to ensure his clients get the best possible outcome. I will continue to recommend him to all of my friends and family, not only because he is a great realtor, but also my sweet husband! :)"

""Herbert is a leader as well as a class act. His knowledge of the Mississippi Gulf Coast Real Estate market is incredible. As a senior agent he has taken time out of his schedule to help coach some of us less seasoned agents. Having wisdom like Herbert's in our office is a blessing.""

Emanuel Fenech

""Herbert is amazing! We met with him to list our camp in Bay St. Louis and he convinced us were thinking of asking too little. Within twenty-four hours he had professional photos taken and the listing was on the MLS. Only four hours after the sign went up,, he had an asking price offer for us to accept! Herbert even drove to meet us in Florence,, Mississippi to sign the contract because we were having computer problems! He made the entire process so convenient. If you ask me,, Herbert's the best agent on the Mississippi Coast!""

Robert and Mary Shaw

Cathy Hamel

""After working with two other agents trying to sell my mother's home in Pearlington,, I hired Mr. Herbert Dubuisson at Gardner,, Realtors. Herbert was a excellent real estate agent . He kept me informed by email,, texts and phone of updated information,, he was quick to my return phone calls,, gave good advice,, did his job quickly,, and was very professional. He also worked very well with our estate lawyer. I wish I had found him first! This is my very honest review.""

Oris Ivory

"Thank you,, Herbert! did an excellent job assisting me in the sale of my home!"

Christine Benvenutti

"Wayne and I both appreciated the professionalism and knowledge in the marketing and sale of our Bay St. Louis,, Mississippi property. I was given his name by a relative and felt secure using his services. Coincidentally,, I had spoken with his father,, Herb,, years back about this same property. Herbert had an excellent role model and teacher in the real estate business. We will still be visiting the Bay in the future,, and staying in vacation houses in the area. Whenever we have the opportunity we will definitely recommend Herbert,, not only for his expertise,, but also his genuine concern for his clients. "

Gwen Heitzmann Pendergraff

"We are very proud and happy customers!!!! Herbert and the rest of the bunch involved made this the best buying experience I ever been through. Thank you!"

Neil Logan

"Herbert,, Now that our home in Diamondhead is sold,, I wanted to let you know just how great it was to work with you! Both James and I have purchased and sold several homes and I can honestly say that you have far exceeded any of our expectations. Thank you so much for your guidance through this process. You made it so much more tolerable. You really are great at what you do! Thanks and take care,, Lori and James Bowman"

Lori and James Bowman

"I wish to thank Herbert Dubuisson for assisting in selling my lots in Waveland,, Ms. Although this was a very small sale and commission for Herbert,, he treated it with the utmost professionalism and enthusiasm as if it were one of his biggest. I would recommend him to anyone to get the job done!"

Linda Ray

"Herbert was great! He listed my lot on December 11th and had an offer for me on December 14th,, we closed on December 21st! I Wish all the Real Estate persons were as efficient and dedicated as he is. He arranged to have me sign the closing papers at my Covington home instead of driving all the way to Waveland and back. All the paperwork was correct and ready to be signed,, what could have been an ordeal became a breeze in no time at all. I certainly recommend him whether you sell or buy. PS: I forgot to mention he has a great smile!"

Helene Aubry

"We appreciate the time and thought you have given us to meet our needs. The condo will be nice when we are finished with the renovations. You did a great job. Hope to see you soon!"

Mary Stacy P. Dempsey

"We recently sold our condo in Florida and needed to identify 3 properties within 45 days in order to complete a tax free exchange. Hebert quickly identified about a dozen properties that met our requirements and we closed on our new condo in just 4 weeks. We highly recommend Hebert and Gardner Realtors if you are looking for Mississippi Gulf Coast property. "

A.B. Dempsey

"Thank you Herbert,, you did a great job for us! If you need a realtor on the Coast and beyond give Herbert Dubuisson a call. He's smart,, hard working,, reliable and above all a super nice person."

Sylvia Smith Hannon

"We lived in Bay St. Louis,, MS,, for about twelve years until Hurricane Katrina forced us to relocate. This year,, 2015,, we decided to ??????let go of the past????? and sell our property. The Dubuisson name on the MS Gulf Coast is very well-known in the real estate field and we did not hesitate to contact Herbert. We conveniently met with him in the Gulfport Gertrude Gardner office,, as we were spending the weekend in Biloxi,, and signed all necessary paperwork to have him represent us in this venture. He was extremely knowledgable of the market in the Bay and advised us well. Our lot was SOLD within eight days of meeting with him. His expertise and gentle manner made this emotional sale a very pleasant one. We highly recommend Herbert Dubuisson. If we had other property to sell,, he would be the only person we would consider!"

Chris and Lelia Olivier

"Herbert Dubuisson did an unbelievable job of listing our home for us. If you want to sell your house you MUST call Herbert. He listed our house on Monday and had it under contract just five days later."

Jay Scarborough

""How do I thank thee,, let me count the ways." From the first day I first met with Herbert at my condo,, 234 Highpoint in Diamondhead,, he showed me respect and dignity with the difficult task of selling my husband's favorite "get away." Throughout the entire process of listing,, having custom photos and a video created and all the advertisement for the condo,, it was all done in a most professional manner. Herbert treated me as his most important client and "went to bat" for me when the need arose. I am most grateful for his expertise and the understanding of my feelings through the entire selling process. Even though we were not permanent residents of Diamondhead,, our stays created memories that will stay with me forever. I hope the new owner finds the peace and tranquility that my husband and I enjoyed while we vacationed and golfed in Diamondhead. I would recommend anyone who needs to sell their real estate,, call on my Realtor,, Herbert Dubuisson! "

"Re: Herbert Dubuisson To write any comment on Herbert,, one must also consider the people who introduced him to the real estate profession and strongly weigh their influence when evaluating his success. Herbert was born into a real estate family,, and not just any family. Both of his parents,, Herb and Patsy,, were legends on the coast. They ran an extremely lucrative company and drew top agents,, who shared the same core values and work ethic they did. Making money was important to them,, but never as important as making friends and setting an example of how agents in our trade should conduct themselves on and off the job. The Dubuisson family was community minded and often recognized for their generosity and good will in promoting neighborhoods along the Mississippi Gulf Coast. Herbert,, literally,, grew up in the family business. His parents took him to work because they wanted to be with him and teach him a strong work ethic. While most children were pursuing childhood games,, Herbert was learning the business of real estate. He had a front row seat,, observing as his parents taught him how to generate leads,, access client needs,, represent them,, and help them realize the dream of home ownership. He also understood the basic fundamental lesson: real estate is a relationship business. I had the privilege to work with Herbert for approximately ten years as a manager in a large firm on the coast. The many repeat clients he served,, the award winning production he achieved,, and the praise and respect reflected in the countless testimonials he received,, are evidence of his dedication and commitment to the real estate profession. Another admirable quality of Herbert?????s is his strong drive to always know more and become better. I met Herbert while I was teaching a national sales training program. He was a committed student,, excelling at every project and skill presented and was a leader and motivator of his peers. Throughout the years I worked with him,, I witnessed a continued quest for new technology and better skill sets to perfect his trade,, which are reflected in the many certifications and designations he earned. Herbert serves our profession well and has stayed true to the values and ethics his parents taught him,, despite a changing market and personal challenges. He is a consummate REALTOR???,, a great man,, and a testament to our profession that doing the right thing and treating people fairly is the key to a long term,, successful real estate career.

"Please accept this document as a testimonial to a wonderful young man,, Mr. Herbert Dubuisson,, Jr. While I have known Mr. Dubuisson for quite some time,, this was my first experience dealing with him as a realtor. After the deaths of both of our parents,, my three siblings and I decided,, after much soul searching,, to sell our childhood home. This house was built quite a few years ago,, in 1958. It seems like yesterday that we were children celebrating Christmas with a freshly cut pine tree from the woods across the street! But,, all good things come to an end and time moves on. I contacted Mr. Dubuisson to help us with our decision to find a new owner for our parents' home. Herbert was extremely helpful in explaining the process and paid close attention to every detail. His use of professional photography was definitely a plus in marketing the house. He always returned my calls promptly whenever I had questions,, and went far beyond our expectations to see that every I was dotted and every T crossed. Herbert really came through for us in finding the perfect buyer,, a young man just starting out in life,, who appreciates the house as much as we do. The closing was held last week,, and again,, Herbert was right there on target! In closing,, I would like to say that my family and I would definitely recommend Mr. Dubuisson to anyone who needs help in the real estate market. Not only is he knowledgeable in his field,, but is friendly and one of the most polite individuals I know."

Vicki Arnold

"Herbert Dubuisson of Gardner Realtors sold our house earlier this year in just a few months ????? significantly faster than we ever believed possible. Our 3-bedroom,, 2,,300-square-foot home sold quickly in a somewhat slow real estate market,, mostly because of the hard work and innovative strategies used by our real estate agent. What?????s more,, Herbert was able to accomplish all of this while my wife and I (the sellers) lived more than 9 hours away. Herbert used new technologies to keep us well informed throughout the entire process. He was able to update us weekly with details on who was viewing our listing online and how often. With his consistent use of social media,, he was able to reach an entirely different group of potential buyers who might otherwise not have known our house was for sale. His dedication and professionalism was extraordinary. His patience and expertise gave us much needed understanding and comfort every step of the way. We could not be more pleased with the outcome and we would not hesitate to recommend Herbert Dubuisson to anyone thinking of buying or selling real estate in Mississippi. "

Ryan and Meredith LaFontaine

"We used Herbert Dubuisson for our recent condo search on the Mississippi Gulf Coast. We had a budget and a general idea of what we wanted in a vacation home. Herbert pointed out pros and cons on various properties and provided us with valuable information in a timely manner. Not only is Herbert an outstanding Realtor,, he loves his job in finding the right homes for his clients. We are very happy with our new home and look forward to enjoying it for many years.

Richard and Diann Williams

"I would like to say a huge "Thank you" to Herbert Dubuisson with Gardner Realtors. Herbert and his team were nothing short of professional,, urgent,, and completely responsive to every need. It's not often that I post on good experiences,, but this was a great experience! It's nice working with a team who exceeds your expectations. If you need a house on the coast,, please get in touch with Herbert! Rachel and David Heaps Bay St. Louis,, Mississippi"

Rachel Grayson Heaps

"Herbert did an incredible job for my husband and myself. So far in five years he helped us purchase a home,, property and within the next year he will be helping us again."
