Location: Wolfeboro

In her role as Principal, Tavia oversees work performed by the firm’s staff level employees, such as audits, reviews, compilations and tax preparation.

Tavia joined Leone, McDonnell & Roberts, Professional Association in 1995. In her role as Principal, she oversees work performed by the firm’s staff level employees, such as audits, reviews, compilations and tax preparation. In her own client responsibilities, Tavia specializes in accounting systems analysis and consulting. She also consults with clients regarding their tax planning, banking and financing needs.

Tavia has extensive experience working with closely-held construction companies, including general contractors and sub-contractors. In addition, she possesses a deep understanding of construction from both sides of the desk. Tavia grew up working on job sites during the summers helping her father, a contractor in his own right, allowing her to develop familiarity with the workers, foremen, job superintendents, needs of the owners and the bankers who serve them.

Tavia began her public accounting career in 1992 at the CPA firm of DiSalvo & Associates, PA. There she assisted with payroll preparation, tax return preparation and write-up work. Tavia also got a taste for the accounting profession in a part-time role at Street Electric, Inc., a family-owned electrical contracting company, where she assisted with all aspects of monthly and annual financial statement preparation. While at Street Electric, Inc., she served as an assistant to the company’s controller, who was one of Tavia’s greatest mentors. Tavia is forever grateful to this mentor, who previously served in the same role for the producers of the “Rambo” series of films with Sylvester Stallone, for the invaluable knowledge and experience she gained as a result of her tutelage.

With an accounting background of more than two decades, Tavia has developed the necessary skill set to provide expert recommendations to help her clients succeed. On numerous occasions, she has assisted small businesses faced with tens of thousands of dollars in software upgrades to utilize much less expensive software and customize it to meet their needs. In another instance, Tavia helped a contractor uncover software problems and recreated their data to help save them hundreds of thousands in tax dollars.

When determining the career path that would best fit her personal interests and priorities, Tavia chose accounting because she felt she could take it with her wherever she goes. She desired a career where she was not forced to sit in one place and do the same thing every day. Tavia’s decision proved to be the right one, as her career has allowed her to travel, meet interesting people, and observe the fascinating and diverse effects finance has on people’s lives. Today she attributes her success to her faith, her supportive family and the first-class working environment at Leone, McDonnell & Roberts.

Tavia was born and raised in Meredith, New Hampshire with her parents and sister. She currently resides in Center Sandwich with her husband and son. Outside the office, Tavia maintains a variety of hobbies and interests, including long-distance swimming, trap-shooting, fine guns, fast cars, big trucks, traveling anywhere with warm temperatures and water, photography, art, cooking and snorkeling. She also enjoys staying actively involved with her son’s activities.

Jonathan brings more than a decade of public accounting experience to his role as Manager at LMR. Before joining the firm, he spent 13 years with a regional accounting and tax firm, advising small to mid-sized closely-held businesses and building a strong foundation in tax planning, compliance, and practical business guidance.

His approach is grounded in clarity. Complex financial situations don’t intimidate Jonathan — they motivate him. He enjoys helping clients and colleagues understand complicated financial concepts in a way that actually makes sense. Clean books, thoughtful planning, and forward-looking advice are where he does his best work. At LMR, he values the firm’s flexibility, strong technology platform, and right-sized structure, which allow him to deliver high-level work while maintaining balance and responsiveness for clients.

He is a Massachusetts CPA and a member of the AICPA, MSCPA, and NECPA. He also passed all four sections of the CPA exam on his first try, a detail he won’t brag about — but we will.

Raised in South Hadley, Massachusetts and now a Greenfield resident, Jonathan stays active in his local community through his involvement with the Friends of the Greenfield Public Library and the Trustees of the Greenfield Public Library.

Outside of work, peers are often surprised to learn he’s more introverted than he appears. He recharges with puzzles, golf, video games, and a steady rotation of horror and sci-fi films and series.
