Why Goodwill is the Most Valuable Asset of a Dental Practice & How to Maximize it When You Sell

Mid-America’s most trusted dental practice valuation and sales

In our previous post, we explained how Goodwill value is calculated in a dental practice: it’s the sale price minus the value of the tangible assets. But numbers only tell part of the story.

So, what is Goodwill really?

Goodwill is the heart of a dental practice. It’s the reputation of the dentist and staff, the confidence and comfort patients feel with their care, and the loyalty that keeps them returning year after year.

This is by far the most valuable asset of a dental practice, usually representing 65–70% of the purchase price—sometimes even more.

How to Protect and Transfer Goodwill

Because it’s so valuable, both Buyers and Sellers should prioritize Goodwill during a transition. Here are proven ways to preserve and maximize it:

  • Keep the process smooth. A “pitbull” attorney who drags out negotiations can damage the relationship between Buyer and Seller, which ultimately hurts Goodwill.

  • Avoid abrupt changes. Cutting staff, raising fees, changing office hours, or criticizing the Seller’s care too quickly can unsettle both patients and staff. Build trust first.

  • Make small improvements. Updating paint, flooring, or equipment can energize the staff and reassure patients, without disrupting continuity.

  • Offer complimentary care. Providing ongoing dental care to the Seller and spouse (excluding lab costs) gives them confidence in recommending you. Patients will notice when the Seller says, “My spouse and I are still patients here.”

  • Leverage the Seller’s endorsement. A strong, heartfelt letter from the Seller at closing reassures patients and encourages them to stay with the practice.

  • Train your front desk team. Receptionists should have a simple, positive script ready: “Oh, Mrs. Smith, I think you’ll really like our new dentist—we can’t wait for you to meet them.”

Why This Matters

Most Sellers are deeply proud of their practice—it’s their life’s work. Being sensitive to that pride, both during negotiations and after the sale, ensures that decades of trust and loyalty transfer to you as the Buyer.

Handled well, the Seller’s Goodwill becomes the foundation for building your own reputation and growing the long-term value of your investment.

Kim with Otten-Rey Dental Sales truly made what I thought would be a stressful process extremely easy and painless. From our first meeting all the way until closing, Kim was always reliably there for me through out the process. I trusted her system and it was simple and seamless. I would definitely choose Kim again for my transition if l had to do it all over again.

When I decided to buy a dental practice, I quickly learned that practice brokers represent the seller. As a buyer, that posed some challenges. Of all the brokers I worked with in St. Louis, Kim was the only one who managed to make me feel that she was actively trying to find a practice for me to buy. Not only did she help me find a practice I loved, but she still represented her seller well and was fair throughout the entire process. Because of her, I am now the owner of a great dental practice that I love and I truly believe she made that happen for me. Thanks Kim.

Thank you both, Kim & Bill. This has been a great adventure. All is going great with the merger of Dr. Berger’s practice. Overall, I would say it is a great success. And I couldn’t have done it without both of you.

I felt my practice purchase went smoothly and efficiently with the help of Otten-Rey Dental Sales. As a buyer, I felt comfortable with the fair appraisal that Otten-Rey put on the practice and both Kim and Bill were very accommodating getting any requested info to help me do my due diligence…Otten-Rey is known in the St. Louis Dental community for being easy to work with and I strongly recommend either buyers or sellers use them in the process of your dental transition. Having their expertise, experience and organization really made things a lot less stressful.

Kim’s understanding of all aspects of a transition was invaluable. She has comprehensive knowledge of both the financial and clinical aspects of a dental office. She also provided the guidance and understanding of the legal aspects necessary to close the transaction. Thanks Kim!

Kim Rey was my broker in representing me when I sold my pediatric dentistry practice. From my standpoint, Kim brought a great amount of stability to the whole process. I appreciate her insight and her levelheaded guidance on what my expectations should be, what the normal accepted practice and standards are when dealing with a buyer. The process was longer than I anticipated, but Kim kept me focused and on the right track until the transaction was completed. Throughout the process, she always made me feel like I could rely on her and that in turn gave me a great deal of comfort. I would highly recommend Kim Rey to anyone looking to buy or sell a dental practice.

Several of my friends used Kim and Bill to sell their practices and had highly recommended them. I was pleased with the thorough process of valuation and the explanation of the report. They provided frequent updates and the guide for printing the necessary reports for the valuation. They found a buyer that fit our needs. I would recommend them to the other dental offices needing the same services.
