Jonathan Mishkin Review
Jonathan Mishkin is a very bright, experienced attorney who recently did our estate/tax planning, and we highly recommend him; he is not only exceedingly knowledgeable in the field (having practiced and taught at U. of Oregon law school for many years), he is very patient and thorough in his explanations of the somewhat difficult field for a layperson to comprehend. His preparation and assembly of the documents are impeccable. We are very pleased with the result.

A lifesaver
I became overwhelmed in a tax situation and was at my wits end. I was referred to Mr. Mishkin, which turned out to be the best thing that could possibly have happened. In ONE sitting, Jonathan cut to the chase, figured out what the so-called 'expert' CPAs had done wrong, and in less than three weeks we have averted a potential disaster. I cannot recommend Mr. Mishkin enough; he is a gentleman to deal with, extremely astute, a consummate professional.

Understands the subtleties
Jonathan Mishkin has been helping my family with complex estate issues and always has the right suggestions to address them. He understands the subtleties of relations between members of the family and is able to take that into account in his planning and recommendations. We've come to rely on him for counsel on non-estate issues as well, such as managing interactions with a recalcitrant rehabilitation center and overseeing the activation of a long-term-care insurance policy. To summarize, he seems to see the big picture and the details it implies, and knows how to negotiate viable, acceptable solutions.

I have the highest regard for Jonathan Mishkin
It was my profound good fortune that my Employee Assistance Program could not find a tax attorney in my area, and referred me to Jonathan Mishkin, 250 miles away--and that he accepted me as a client. I was facing an insurmountable tax liability, and felt consuming anxiety. In the first phone call, however, his knowledge, expertise, and advice gave me hope, and it felt like a great weight had been lifted. Throughout the process, his behavior was compassionate and nonjudgmental, he knew exactly how to proceed, gave me clear directions, knew what information was relevant, responded to my questions promptly and thoroughly, kept me apprised, expertly knew IRS policies, requirements, and expectations—was in every way excellent. Proof of that is the letter I received yesterday from the IRS—our Offer in Compromise was accepted. The outcome was the best imaginable—and he has my deepest gratitude. My future now looks very different than it did four months ago. .

extremley positive experiance r.e. jonathan mishkin
iam 65 years old. i have been representled by numerous attorneys over the years. mr. miskin represented me on what i was sure was a hopeless case for tax liability. it was completely overwhelming amount of money i didn't have nor would ever have. this area of law is known for some very bad people. mr. mishkin not only did exactly everything he said he would right from the start but always called me back immediately when i would have one of a many questions. he was able to get me a settlement with both the irs and state that i could live with, a much better deal than i ever thought possible. the financial terms he quoted me from the start and the time frame to settle the case were exactly as offered. mr. jonathan mishken was without a doubt the best attorney i have ever dealt with.

knowledgeable and responsive to all concerns
Mr.Mishkin, kept us informed and in the loop with emails and phone callls. Since we live out of state this gave us a great deal of comfort. Our concerns where always adressed with knowlegde of the law and with an open mind. Mr.Mishskin, was trustworthy and very conservative in his billings. We would recommend Jonathan, to anyone that needs an lawyer.

Tax Help
Jonathan was able to step in very quickly and provided us with a complete and through protest on an IRS tax case. His knowledge and experiance of the tax laws was no doubt the reason for our successful protest. He was very open and honest in his communications and willing to listen to our needs and concerns. I would highly recommend Jonathan to help with your needs.

A Good Lawyer Experience
Was referred to Jonathan to handle a tax case involving the IRS and a family business. Jonathan jumped in right before the holidays and put together a thorough, effective appeal that resulted in the IRS dropping the case. Jonathan was very good at keeping us informed on his thinking for the case and his strategy. He was very responsive to our questions and concerns. We felt he made effective use of our time and money and wasn't just "nickel and diming" us. We couldn't have asked for a better experience with an attorney.

Experience with Jonathan Mishkin
My family has been working with Jonathan for several years on a number of challenging estate planning issues. His help has been invaluable. Not only has he been timely in helping us ensure that we have all legal documents required, he has been creative and thoughtful about how to solve many challenges. An added plus: Jonathan is easy to talk with openly, which ensures that thorny topics surface and get addressed. I feel in very good hands with Jonathan and my mind has been put to rest about many concerns. I highly recommend him!

Jonathan was very professional and worked in a timely manner. We asked him to do some estate planning for us. He was a pleasure to work with. In addition to being very knowledgeable, he was just a pleasure to work with. He laid out all our options and the work was done thoroughly and quickly. He was very responsive to any questions we had and continues to check in with us periodically to make sure we have followed up on the things we needed to.
