Jonathan engages in a sophisticated civil practice encompassing estate planning and administration, corporate and banking transactions, intellectual property, and real estate law. He works with both individuals and businesses to fashion innovative plans and strategies to accomplish his clients' objectives.
Jonathan has extensive experience in crafting estate plans and preparing wills, trusts, powers of attorney, and advance directives for health care. He has advised clients with both small and large retirement assets, and provides the same level of personal attention to each client. Jonathan has a special interest and expertise in creating plans that address the unique considerations involved in transferring ownership of family legacy properties to the next generation by creating a trust or LLC and mediating family differences, resulting in a structure for the succession and management of the property.

What allows me to be effective as an attorney is the growth of trust. By being worthy of a client’s trust, and by in fact being trusted, I offer a level of service that is more individual, more intuitive, and more helpful.

Jonathan also has represented numerous business clients, both as buyers and sellers, in merger and acquisition transactions and banks in commercial financing transactions. He has assisted and advised Maine companies in seeking and obtaining venture capital and on their ongoing operational issues. He serves as the “go to” counsel for various Maine companies, and in that capacity has negotiated a wide range of business contracts for his clients and provided counsel on many business issues. 

Jonathan’s real estate work has included a large multi-use developer of a project in Casco Bay, the grantors of significant conservation easements, a developer of several large residential subdivisions in Bar Harbor and Mt. Desert, as well as the purchasers of vacation homes. 

Finally, he has prosecuted and maintains dozens of trademark registrations for his business clients.

Jonathan lives in Auburn. In his free time, he grows flowers, makes photographs, kayaks, and enjoys being outdoors in Maine.
