"I would highly recommend Diablo Hills (Accounting).  Hillary and Sue helped me get my business books set up when we launched the business, and they continue to keep me on track.  They really know Quickbooks and understand small businesses - patiently answering all my questions and giving sound advice.  For an absolutely top notch professional bookkeeping can do no better." - Jim, 6/6/13

"Great service - accurate, fast, responsive, flexible.  Hillary has adapted to our unique systems and processes, and she also goes the extra mile by looking for areas where costs might (be) reduced." - Dave, 2/9/10

"I have been working with Diablo Hills (Accounting) for a while now and have been extremely happy with the high level of professionalism and reliability I have received from them for what they charge.  They are accurate and thorough and my small business has been helped quite a bit.  Simply excellent."  - Eric, 4/8/10

"I have known this company since they opened and have worked with them and referred all my friends and clients to them.  The owner has run a small business before so she understands how they work and make(s) awesome recommendations.  They have delivered clear books to my CPA so at tax time I don't even sweat.  Their customer service is amazing, they sincerely want to help small businesses in this tough economy time.  Also I have to add that they are VERY professional, fast, thorough, accurate AND reasonably price(d).  If you are looking for a good bookkeeper, give them a try and you will NOT be disappointed.  (They) still do my bookkeeping even since I moved to (Huntington Beach) since everything is done via internet.  They have made my life so much easier..." - Nousha, 4/19/10
