What we specialize in
Some books are not like the others.
A veterinary practice, a broker-dealer, and a framing contractor need three different accountants. We have all three on staff, and the person who leads your account is named here.

Our approach
We talk to you through the year, not just at filing time.
Most accounting relationships run on a once-a-year rhythm: records go over in February, a return comes back in April, and the decisions that actually determined the outcome were made the previous June with nobody to ask. We work the other way round.
01
A named accountant, not a queue
Every account is led by a CPA from our team whose experience fits the industry: Ed for a veterinary practice, John for a contractor, Anthony for a securities firm. You get their direct email. You do not get reassigned each year, and you are not explaining your business to someone new every February.
02
Year-round, not filing season
The work that changes an outcome is planning, and planning has to happen before the year closes. We stay in contact through the year so that the equipment purchase, the compensation change, the new partner, or the sale gets discussed while there is still a decision to make.
03
Reporting you can act on
Financial statements are only useful if the person running the business can read them. We prepare statements that satisfy a bank, a bonding company, or a buyer, and then go through what they say about the business in language that survives being repeated to a spouse or a partner.
04
One firm for the business and the owner
For an owner-operated company the business return and the personal return are the same decision written twice. We prepare both, which is the only way to see the whole position rather than half of it.
Clients, on the record
Two of these have been with us more than thirty years.
“We have been with Jacobs and Newmark for over 30 years. Our success is directly related to our relationship with Jacobs and Newmark. They know us and they care about us and it shows in their work. I would recommend Jacobs and Newmark to anyone who is looking for an accounting firm that offers personalized service. They can help through the ups and downs of being in business over the long haul.”
“Ed Newmark is one of our most trusted advisors and a team member. He does a professional job preparing our financial statements and tax planning for our 4 separate corporations. We respect Ed for his sound, practical advice on issues from buying or lease a piece of equipment to relocating.”
“Whether it's handling a bank, IRS or union audit, balancing the monthly journals, filing quarterly taxes or giving sound financial advice, and explaining it all in terms we can understand, Jacobs & Newmark accounting services have been an essential asset to the success and growth of our business for more than 30 years.”
