Sibylle Grebe's Lawyer Endorsements
"I endorse this lawyer. I know Attorney Grebe from her work with the Beverly Hills Bar Association. Whenever I have estate or probate matters I know I can call on her. If you or a loved one have estate questions they should call attorney Sibylle Grebe."
"Ms. Grebe is the consummate professional for estate planning. She is expert at preparing wills, trusts, and related documents. She is also expert in interviewing her clients to make certain their needs are addressed in the documents that are prepared; and also that they understand the documents and the process."
"I have been pleased to know Sibylle ("Siby") for several years after first meeting her in a professional group focused on Elder Law. Lawyers constantly consult with each other and over time I have found her accessible, sensitive, thoughtful, and with a practical approach to legal problems. She is a concerned advocate for her clients and has been particularly helpful to me in the area of conservatorships. So I am very comfortable recommending her to anyone needing estate planning, probate or conservatorship assistance."
"I endorse this lawyer."
"I endorse this lawyer wholeheartedly. I am quite careful as to who I refer clients to in the area dealing with Conservatorships and Guardianships and Sybille is one of the best attorneys I know in the Los Angeles area. She is not only knowledgeable, but she will think out of the box when needed to come to a good outcome. If you or your client needs a great conservatorship attorney, Sybille will be someone whom you should interview. I would rate her a 10. Avvo has it wrong."
"Sibylle is an outstanding lawyer for probate and conservatorship matters. She provides a very personal touch in her work with clients, and is known in the community as a great advocate for senior rights and services."
"Ms. Grebe is a highly skilled attorney in the probate and conservatorship areas. She was opposing counsel in a very challenging case that settled in the last hour of trial solely due to her negotiation skills. I highly recommend her."
