 "Will and Leonie both bring years of real estate sales, legal, and title experiences for the benefit of their clients. Their high level of professional representation is one of the main reasons I continue to work with them. Their staging is always on point and really highlights the interior features of even the most basic home. They are also genuinely a nice couple and good people!"

 "I cannot imagine a more friendly, more helpful, more knowledgeable, more trustworthy pair of realtors than Will Tanaka and his partner Leonie Lam. They were always ready to answer any questions my wife had, and to answer them with the greatest clarity. Furthermore, they were very proactive in seeing that the property was in the best possible condition to get a very good price on it. And, on top of that, it seemed to me that they often patiently and energetically went beyond the call of duty to deal with some problems that arose with the state of the property after the last tenants had left. I always felt in completely safe hands with Leonie and Will. Perhaps, as well as being realtors, they should consider being counselors too, because any anxieties I may have had always melted away when I was talking with them! I challenge anyone to find better realtors than Will and Leonie!"

 “This was an estate sale that needed quick action. Will is very knowledgeable on Real Estate laws for probate. Will Tanaka and partner Leonie Lam took all the stress and pressure off me as I was grieving the loss of my husband. I was very happy with the pricing, staging, and recommendations to make the property shine. My property was in escrow within two days of listing in the MLS and I had multiple offers. I live on the mainland and Will's communications in each step of the process was seamless. I highly recommend Will Tanaka and Leonie Lam as a team of experts and experienced professionals to sell your property.”
