  • “We have been working with DSWD since we started our business 5 ½ years ago. They were instrumental in not only helping us put together our business plan and set up our business, but have continued to provide us with guidance that has allowed us to grow in a significant way. Our success is directly related to our relationship with them.”
    Marilyn Versten - Trifecta Transport LLC.
    “Our lives have been a great deal easier since we moved our Accounting Business to DSWD. Not only are we able to file our taxes on time, they provide solid advice throughout the year and are always there to answer any questions we might have. One of the best business decisions we have made over the few years. Thank you for all you do.”
    Mario Spina & Pete Mancini - Parent Petroleum Inc.
    “Joseph DeMarco and the whole company typically make everything so much easier than we expect. They are perceptive, prescient, and responsive to our accounting needs, which are varied. We use the firm for business, taxes, and real estate and really can’t think of an instance that Joe’s insights didn’t save us either time or money.”
    LJ and Rita Hoke - satisfied customer
  • “Our relationship with the partners stretches back decades. As our firm’s business has evolved over the years, the team has been responsive and knowledgeable. Although auditing is a regulatory mandate, we are always kept informed about trends and best practices, which makes the process valuable to Cantella.”
    Jay Lanstein - CEO Cantella & Co. Inc.
    “I would like to thank Rick and his team at DSWD for exceptional service. Rick and his team offer a personal commitment to addressing and mitigating our business accounting and tax needs. Year after year, our team has learned to depend upon the flexibility of Rick and his approach and the ease of use of his team’s services as well his dedication to supporting our needs. Rick and his team have become a trusted partner from the moment we opened our doors in May 2011.”
    Scott Upp - Cosourcing Partners
    “We have been clients of DSW&D since its merger with Dunleavy in 2010.  We have always found them to be easy to work with, dedicated to serving their clients in a professional manner and to be well informed and up to date regarding the broker-dealer industry.  We have recommended them to other broker-dealers on several occasions.”
    Brian L. Clark CEO and President - Patrick Capital Markets LLC.

    In times when true loyalty and attention to detail is lacking, they have stood with us in navigating all of the complexities that have arisen in this fast paced, competitive business environment. They truly are partners. I am confident that anyone who chooses to use DSWD will never need or desire to partner with any other CPA firm.
    David M Torelli CPA MBA, CFO - The HOH Group, Inc.
  • Our firm worked with this company for the first time last year and had a great experience. They were professional and thorough, and we look forward to continuing to work with them in the future. We would recommend their services for broker-dealer/investment advisory firms.
    Crystal Weber, Operations Mgr. - FSB Premier Wealth Management, Inc.
    Richard Wilkens has been our company's accountant for several years. His knowledge, professionalism, and friendly easy going manner take away the burden of accounting. He is always available to answer questions and give advice. He has a wide range of contacts to help with other financial matters. In a world with impersonal computerization of accounting, Mr. Wilkens customizes the pertinent issues to solve your needs. I enthusiastically recommend him without reservation.
