Timothy E. Sheridan, J.D., President and Founder ​


Tim Sheridan has been providing insurance and risk management solutions to the Healthcare industry for 19 years.  His career started in a family owned agency that was subsequently acquired by a large publicly traded organization in 2004.  After being promoted to Area President, he decided his client’s needs were best served in the private sector where outside pressures do not influence the relationship.  With that in mind, he formed Sheridan Insurance Group, which focuses exclusively on professional liability insurance for Physicians, Physician Groups and Locum Tenens organizations on a national basis.  With expertise on a national level from first dollar coverage to all forms of self insurance program creation and management, Tim is able to customize programs specific to his clients’ needs while improving their coverage and reducing their total cost of risk. ​

Tim received a Bachelors of Business Administration from Baylor University and a Juris Doctorate from South Texas College of Law.  He is also a member of the State Bar of Texas.  In his spare time, he enjoys anything related to automobile racing, golf, fishing and just about anything outdoors. ​ ​

Heather Plunkett, Producer


Heather brings a unique perspective to Sheridan Insurance Group. Prior to working in insurance, she was a physician recruiter specializing in Locum Tenens staffing. It was her job to build relationships with the physicians; taking into consideration their specific set of circumstances and needs. It was never about just making a placement, but, ensuring it was a good fit for both the physician and the facility. Working in insurance is much the same thing. Anyone can sell insurance; but not everyone understands the specific set of circumstances for each client. Partnering with someone who understands the industry from all sides, is a benefit few agencies can offer. In addition to working in the Locum Tenens world, she also partnered with physician groups and private practice across many specialties to find the right fit for Allied Health professionals. In all of these situations, the malpractice insurance was of the utmost importance for both the provider and the business. This made the transition to medical malpractice insurance a very natural fit.

When she isn’t talking shop with clients and potential clients, she’s a mother to five kids…yes, you read that correctly, FIVE KIDS. Oldest is in college, youngest is in elementary school, so, there isn’t a situation she can’t overcome. Thankfully, she doesn’t do this alone, her husband of nearly 20 years is right beside her helping to manage the team!  She says having a sense of humor is the most important thing in life: you have to laugh and have fun, whether at work or play. She enjoys meeting new people and derives genuine satisfaction from helping others.
