9 Items to Consider When Contemplating the Sale of Your Veterinary Practice

October 27, 2021

For many veterinary practice owners, aspirations of selling your practice may be tempered by the unknowns of the acquisition process. Even when the circumstances of a potential sale are ideal, unfamiliarity with the market and sale procedures can lead to hesitancy. While timidity toward the unknown is certainly justifiable, owners should not let it stop them from becoming a participant in the rapidly growing market for veterinary practice acquisitions. While each veterinary practice sale is unique in its own right, there are also a number of procedural commonalities that appear in nearly every deal.

Peter Tanella authors article for Today's Veterinary Business titled "Stay Away, Please"

February 16, 2022

"Common in veterinary practice transactions, restrictive covenants are designed to prevent the seller from soliciting clients and competing with the buyer after the sale. Through such restrictions, buyers aim to protect themselves and ensure that the acquired business does not lose value due to the seller's re-entering the market. To fulfill those objectives, a purchase agreement's restrictive covenants should be negotiated, clearly stated, endure for a reasonable period (for example, two to five years) and be practical in geographic scope." Chair of the National Veterinary Law Group at Mandelbaum Barrett, Peter Tanella, Esq. authors a regular column in Today's Veterinary Business called "Legal Lingo." In the current February/March 2022 issue, his article titled "Stay Away, Please" discusses how restrictive covenants serve a critical purpose in a newly purchased clinic's continued success.
