John Olivero
I have been serving the real estate needs of Orange County's homebuyers and sellers since 1990. Because I take an education/counselor-based approach, I treat all my clients with the same professional respect and straightforwardness that has helped earn my reputation for honesty and hard work in this industry.

My service area and client base spans the entire Orange County School Districts, as well as those with properties located in lower Ulster and Sullivan Counties. The history of Griffith Olivero traces the converging successes of two companies: Thomas and Mary-Gray Griffith founded Griffith Realtors in 1965 and established its Goshen, New York office in 1968.
Services
Back in 1990, I was in the market to purchase my first home. As a first-time home buyer, I didn't even know what I didn't know about buying a home. Let's face it, buying or selling real estate is more likely than not going to be the biggest financial decision we make in our lives. So during the process, I read everything I could about buying a home.
I offer a comprehensive range of services for all your real estate needs, whether you're looking to buy, sell, rent, or lease. Give me a call today. You'll be glad you did. I'll guarantee it. As an independent and full time broker I have had the privilege of helping hundreds of families with their real estate needs right here in Orange County since 1990.
One of the many things I love about real estate is that no two transactions are alike. Real estate is a very emotionally charged business. To a large extent when selecting an agent to assist you in the marketing and selling of your home you have a tremendous amount of options. Most everyone knows someone with a real estate license.
I believe in doing a few basic things right all the time can be the foundation of a strong business. That is why I am always available to my clients and I always keep them informed. I respond to their questions and concerns in a timely fashion. I am punctual. I keep myself updated and maintain access to all the tools necessary to achieve the goals of those I serve.

John was professional, thorough, and extremely detail oriented. He went above and beyond and as a result we had multiple offers on our home over two days. We would highly recommend him to anyone looking to buy or sell a home.

John is a top of the line pro. For every encounter that we had with John, he was professional, punctual, and incredibly knowledgeable. We bought our new home and sold our previous home in a timely manner due to John’s incredible diligence. To put it simply, John is the best that there is. You will be very happy with your home buying/selling experience when working with John.

Deirdre was great to work with! She was very mindful to all of our requests when looking for our forever home. She also made our selling process very easy for us. She was available to us whenever we wanted to go see a house we were interested in. If she couldn’t be available to us her partner John was there to answer any questions we may have had. They make a great team, I highly recommend them anyone who’s thinking about starting the search for a home!

We were very satisfied with the service of this provider. We tried lining up with a few other realtors that just didn't seem to work out, but John was always quick to respond and flexible in working with our schedules to meet up. We were looking in a busy market in an area in high demand, but he was able to help us get into a home for our family that we are very happy with.

John Oliver was great from the very start. They were very responsive and contacted me right away to help learn more of my needs and wants. I felt comfortable as a first time home buyer when working with them. Deirdre was very pleasant and professional and it was great working with her. John Olivero Real Estate made the process as easy as possible and it was a great experience that I would highly recommend to anyone looking to buy a home.
