Board Certified in Estate Planning and Probate Law

Michael Carroll

Mike was born in Port Lavaca, Texas, making him a native Texan! He received his undergraduate degree from Baylor University (BBA 1980 Magna Cum Laude) and received his J.D. from Baylor University School of Law (JD1982). At Baylor he served as an associate editor of the Baylor Law Review. Mike is a member of the State Bar of Texas and the Real Estate Probate and Trust Section of State Bar.

Mike originally practiced mostly in the area of civil litigation. But after several years of battling for his clients in court, he began to work at keeping his clients out of court through proper planning. He soon assumed the duties of taking care of the estate planning and probate matters for employees and families at the firm where he worked, which lead him to switch the emphasis of his practice solely to estate planning, asset protection, and probate. Mike was named a 2017 Five Professional by Five Star Professionals.

Mike has served as chairman of his church Board of Trustees and its Finance Committee. He also served several terms on the Board of Directors of Habitat for Humanity. Mike is a member of the Lake Travis Chamber of Commerce. He and his wife Lu have five children and 9 grandchildren.
