Highly Recommend HKP!

I hired Mr. Kienle to defend me in a trust litigation matter. He was courteous and professional, and his depth of expertise in such matters was obvious from the start. His fees were very fair and he did not inflate his charges. The outcome was successful and I would hire HKP again.

Excellent Trust Litigation Attorney

I have worked with many attorneys in various capacities over the years. This was the first time I have ever needed representation. I met with and hired Mr. Kienle to represent me and my father's estate. Mr. Kienle was very knowledgeable in trust law, something that evident throughout the case. He w...ent over and above in his communication with me throughout the entire process. He was very responsive to phone calls and emails. Mr. Kienle was always respectful to the court and well prepared. It was evident this was noticed by the Judge handling the case. If you are ever in the position of needing a trust litigation attorney, I would highly recommend Mr. Kienle.

General Litigation

I hired Andrew Kienle to represent me when my claim to ownership of my house was challenged. I found him to be professional and knowledgeable as he guided me through the long and frustrating process. He was available for questions and explanations and his strategies and insights brought the result...s to a favorable ending. During the process the house was sold before the case was over and Andrew's real estate expertise helped make that very complicated process flow smoothly. I would highly recommend Andrew Kienle and Hart Kienle and Pentecost.

Estate Litigation Success

Andrew Kienle’s knowledge of the law and his professional manner are excellent. I hired Andrew to represent me in contentious trust litigation involving family members fighting over their share of inheritance. This was a difficult time for the whole family, but Andrew’s litigation and courtroom proc...edures exemplified his experience. He is a real asset when dealing with estate litigation. Above everything, he possesses a level of integrity that is rare in today’s world.
