The Green Sail Difference

Both buyers and sellers often ask "where do I start?" The GST team will always answer the phone to advise you! We will listen. We want to understand your unique goals and objectives, after all, everyone has different visions and needs. Furthermore, every dental practice is different and each dentist has different skill sets.

Sellers

Whether you are ready to sell today or are just gathering information about a future sale, you've come to the right place. We have different levels of practice valuation services ranging from a free, do-it-yourself version, to a complete valuation ready to use as a beautiful marketing piece for your practice.

We also offer equipment-only valuations and our exclusive "Financial Appraisal" that is a lower cost way to determine your exact value for sale "consideration" or future sale planning.

Valuation Options

Comprehensive Valuation: Appropriate for practice sales. Fee is refunded at closing from sales commission.
Financial Valuation: Appropriate for accurate value for planning purposes such as bringing in an associate with a buy-in option, selling to someone who is already familiar with the practice, etc. This service is a reduced fee since all the narrative and photographs are not needed.
Value Estimator: This option is offered to determine an estimated value that is appropriate only for planning purposes. It should not be used to determine values for immediate practice transitions.
Equipment Only Valuation: If you just need to have your equipment appraised, we provide that service as well.

Buyers

Perhaps you are wondering when you should start looking for a practice to purchase or when it makes sense to apply for financing. We can help you whether you are ready to own now or just thinking about your options. The first thing you need to do is join our email notification list to keep up to date with the practices available.

Members of our email notification list receive regular updates on practice listings, associateship opportunities, Hygienist and assistant positions, market news and special notifications and offers.

When you sign up let us know where you would like to locate and what size/type of practice is right for you. Green Sail Transitions keeps meticulous records of our buyers and their needs.

We specialize in dental practice sales, acquisitions and mergers.

John is an absolute GEM. Practice transitions are complicated. As a seller, having John by my side every step of the way made the process manageable. Whatever it was I needed- support, empathy, advice, information or just a good laugh- John was there 24/7. He is incredibly knowledgeable and well connected in the pacific northwest dental market. Highly recommend John and Green Sail Transitions when it comes to buying or selling a practice in Oregon and beyond.

For the past three years, I had been looking for a dental practice to purchase. Green Sail Transitions has been helping me pretty much the entire time. They went on multiple trips to prospective practices with me to help me find the right one. Nancy in particular would send me info on practices she thought would be ideal for me without me even asking. They didn't stop helping after we found one and continued to guide me through the purchase. I would not be typing this from my new office if it weren't for their dedication and assistance. 🙂

Nancy, John and AJ were fabulous to work with. They were always available, responsive and handled everything professionally and quickly. They did a great job marketing the practice and had buyers vetted and ready. They have a great relationship with bankers, accountants and attorneys in the area and were able to overcome issues that would have been difficult otherwise. Their experience was indispensable and I would recommend them without any hesitation.

I am so thankful for John Van Leeuwen and Green Sail Transitions managing the sale of my dental practice. John was punctual, efficient,
professional, thorough, available and personable. He guided me through the process
seamlessly. He was very helpful to not only me,
but also the dentist buying my practice.
Facing a heart surgery, it was such a relief to complete the process in 3 months.👍👍❤️
