Princeton/Red Bank, NJ & Bethesda, MD – Effective yesterday, Portal Solutions, an information technology consulting firm based in Bethesda, MD, joined its practice with WithumSmith+Brown, PC (Withum), a regional CPA and consulting firm with 14 offices, 900 staff members and annual revenue of $140M, ranking in the top 30 firms in the country. Portal Solutions will remain at their locations in the Woodmont Triangle neighborhood of Bethesda and Woburn, MA.

“We are excited about joining forces with Withum,” says Daniel Cohen-Dumani, the founder and Chief Executive Officer of Portal Solutions, who will join Withum as a partner and continue to lead its growing advisory practice. “Since the inception of Portal Solutions in 2003, our primary focus has been to provide remarkable client experiences while creating the best possible digital workplaces, always putting the client first. The fact that Withum embraces personalized attention and a commitment to excellence is tremendously important to us.”

According to Cohen-Dumani, the two firms’ combined resources will bring a new breadth of services to Portal Solutions’ clients. “Withum’s considerable resources will accelerate our expansion in data and analytics solutions, mobile development, security and risk assessment, managed services and modern business applications with Microsoft Dynamics 365,” he says. “It will also allow us to further expand our overall solution capabilities to offer packaged solutions, such as OneWindow Workplace intranet, in industries such as healthcare, professional services, non-profits, real estate, financial services and others.”

Withum’s Managing Partner and CEO Bill Hagaman, CPA, CGMA, also noted that Withum has been seeking the right strategic partner to enhance its management consulting services.

“We found the perfect match with Portal Solutions in terms of service expertise and culture. We are thrilled to have the talented staff from Portal Solutions come on board,” he says. “We are excited to now offer clients digital workplace solutions, which aligns with our overarching strategy and business objective to bring together people, processes, technology and data in order to propel their growth and success. Our union will allow us to immediately offer our clients cloud-focused information technology consulting services supporting Office 365, Azure cloud solutions, data analytics, business process automation and mobile development and security. It’s very exciting.”

“Withum’s innovative mindset and value added approach to servicing its clients was a big attraction to Portal Solutions,” commented Allan D. Koltin, CEO of Koltin Consulting Group who advised both firms on the union. “Although Portal Solutions was courted by many other Top 30 accounting and consulting firms, they felt Withum’s entrepreneurial culture and ability to grow in the technology area were major strategic advantages in their reaching a decision.”

Combined, Withum and Portal Solutions serve a wide range of industries. These include technology, financial and investment, healthcare, law and professional, government, life sciences, not-for-profit and education, manufacturing, automotive, consumer products, construction and real estate services.
