Appointment/Financial Administrator – Susan Brown
Susan has been in the dental field for 19 years. She has worked both front and back office, and now considers herself to be a specialist when it comes to insurance, billing, and treatment coordinating for patients. She has taken various courses in dental billing, implants, sedation, legalities of dentistry, and first aid. Susan loves the field of dentistry and the satisfaction it gives you to see a patient get out of pain, be it physical or emotional, due to a dislike for their smile.

She finds great joy in being with her grandchildren. Susan also has 3 cats, 4 dogs, and a turtle in her home.
