Our Practice Areas

Practice Buyers

Whether you are purchasing a practice for the first time or expanding, we have a wealth of experience to educate you and help guide you through the acquisition process using our innovative "3 Stages" approach. From entity creation through closing, we provide full-scope buyer representation services.

Practice Sellers

Selling a practice can feel overwhelming, with a lot of moving parts. We frequently work with sellers who are retiring or who have a change in life circumstances to help them feel calm and in control during this major life transition. Whether you have 1 office, multiple offices or considering selling to a large management organization, we can help.

Leases & Real Estate 

From comprehensive lease reviews for start-ups to the purchase of commercial real estate for your practice, we can help you through a flat-fee approach to keep costs lean while maximizing advocacy to you. 

Partnership Changes

Partnerships are a popular means to expansion and to secure talent through ownership. We assist with buy-ins for associates seeking to become partners and buy-outs for exiting partners. 

Employee Agreements for Employers

Expansion and growth often triggers the need to hire more talented associates. We help draft and negotiate customized associate agreements that will streamline your employment process.

Employee Agreement Reviews for Associates

Non-compete clauses, compensation, claw-back provisions can all be very confusing for a professional seeking employment. Whether you are newly-graduated or changing practices, we can help.
