    We needed a new accountant. Our old one wasn't getting it done. I had previous contact with Mark 20 years earlier. His name came up as a possible replacement for our accountant. I immediately knew this was going to be a good choice. The only sad part is I didn't look him up for our accounting work 10 years earlier. He knows his stuff inside and out. He files all the legal claims and never misses a beat. Totally recommend him.

  • As a Real Estate Broker, General Contractor and Landlord, I rely on Mark's knowledge to help me plan for and prepare my personal and business tax returns. I have been referring my friends and customers to Mark Undis for several years for the their individual and business tax preparation and tax consulting needs. I am very picky about who I refer people to. Mark is the first CPA I have referred anyone to! I recommend Undis CPA without hesitation.

  • When I changed from my old CPA to Mark Undis, he immediately found and filed for refunds that the old CPA missed. Besides saving money on taxes, Mark also handles my personal taxes, and has given me some good advice on saving money on other things too, like insurance. Mark really gets to know his clients on both a business and personal level to best serve their particular situation. I would definitely recommend Mark Undis to any small business who wants a CPA more in-tune with their needs!
