I have worked with ***** for about a year now. She handles the books for my business. I have found her to be patient, thorough, knowledgeable, and very helpful.I highly recommend her services.

From:  Marc Immerman, COO of ProConn Power, Inc.       “While in the midst of downsizing the company our CEO and founder passed away, leaving the company in complete disarray.  Aside from layoffs across the country and the closing of two offices, the financial records and filings were a major disaster.  We were very fortunate when Kathy came into our lives, as she has been an extremely valuable addition to our team.  She has been instrumental in completing the forensic accounting and reconciliation that was so badly needed not only to straighten out our books, but for tax purposes as well.  Her work ethics are only paralleled with her attitude towards getting the job done.”

From:  Mary Ganapol, Owner of  Seniors Helping Seniors   “As a new owner of a small business, I was struggling to prepare my paperwork for my year-end tax purposes.   Over a number of visits, Kathy helped me clean up accounts and organize my data in a clear, methodical way.  She helped me understand QuickBooks at an advanced level so my reports will be accurate and meaningful going forward.  She is great to work with, patient in answering all my questions and non-judgmental about my novice level of expertise.  As my business grows, she will continue to be my ‘go to’ person to help me with all my accounting needs.  Such a blessing!”

From :  Mark Meginnes, Owner of Plane Care, LLC.    ” I have been one of Kathy McDowell’s Clients since 2011 and she formalized my finances and accounting practices at Plane Care.  I started this business at Tucson Ryan Airfield in 2009 and did not have my business set up in QuickBooks or in any form relating to  payroll and accounting.  She put in hours and hours to get my books presentable and ready for an audit with the AZ Department of Economic Security.  She did this out of the goodness of her heart, because of her belief in Plane Care.  At Plane Care, Kathleen McDowell has taken care of the payroll, taxes, invoicing, and customer service.”

From: Bruce Stoddard, Director of Wright Flight, Inc.  “Kathleen McDowell has been working for us since January of 2012..  I have come to rely on her skill sets and expertise when it comes to tracking the finances of Wright Flight, Inc., a Federal Tax-exempt 501 C 3 corporation. Ms. McDowell has brought her talent to our operation and made all aspects of our bookkeeping more accurate and has been proactive in ideas to make sure our financial ship is in order.  She has helped clean up old files and also brought in new ideas to set-up our next fiscal year to start out on the right financial footing. I admire her work ethic and industriousness.  She is a valuable part of our team and makes it easier to pursue our efforts in bringing our program to over 1000 youngsters this school year and introducing  them into the world of aviation.”
