Alfredo “Fred” Dimaculangan established the entity in 1984 under sole proprietorship. His wife, Ma. Teresita Socorro “Marites” Zuniga- Dimaculangan later joined him, doing audit work on a part-time basis, bringing with her the assurance audit experience.

In 1985, the Dimaculangans registered the Firm as a General Professional Partnership (GPP).  With their combined experiences and expertise, the couple/partners was confident that their new firm would take off immediately. They initially built their network through referrals, friends and previous employers.

In August 1987, Marites left her full-time job to co-manage her husband’s business. Her formal presence in the company added a number of clients—those who followed her from her former job—to the new firm.

However, the Firm went through the proverbial birth pains and learning curves. Limited quality clients, fast employee turnover rate and low returns on investments were some of the obstacles along the way. To better equip herself to cope with the challenges of managing the growth of DD & Co. CPAs, Marites took the opportunity to enrol in an entrepreneurship program at the Asian Institute of Management (AIM). The lessons she received on entrepreneurship enabled her and Fred to revitalize the firm. From a few remaining staff of 2, they hired 15 more. From 20 clients, they acquired 40 more.

Today, Dimaculangan, Dimaculangan and Company CPAs is a highly-acclaimed CPA firm in the Philippines. Our record of accomplishments with our clients and our colleagues has backed us up through the years. We pride ourselves in making a complicated service understandable, such that we are able to explain in simple terms what appears to be in “technical terms” for the non-accountants.

What was formerly a micro enterprise is now a medium-sized Firm, and still growing! As we approach three decades of accounting excellence, the company continues to invest in quality service, integrity and people. We provide a venue for professional growth through internal and external assessments of its environment, seminars on skills and regulations, and exposure to the spectrum of its financial services. It closely works with every client and is adept not only in accounting and auditing but also in legal and tax matters.

DD & Co CPAs now works with quite a number of employees and 200 clients, mostly in the manufacturing, real estate and condominium industry. Our employees are trained to deliver beyond the traditional auditors—to accomplish a job order with an added value that would help businesses understand the complexities of their financial condition and make more appropriate business decisions.

When need be, we also offer a lending hand to foundations on a “pro-bono” basis as part of our Corporate Social Responsibility (CSR).  We see ourselves as a sounding board for clients, in the sense that not all Accounting Firms give their clients financial counsel.  Presently, DD & Co CPAs’ advocacy is to educate SMEs on financial literacy by using accounting data as a tool to sustainability and growth of an enterprise.  The Firm believes that given proper perspective on the use of accounting data, a business owner would realize that the financial statements can help them better navigate their business to success.
