Your logo says a lot about you. The colors, shapes, and fonts you use all have an impact on the message and trust it conveys. Consider what message you want to convey as you design your medical logo. For example, as a pediatrician, you might want a logo that says, "this office is a safe, friendly place where children come to get and stay well." As a cardiologist, you could select a logo that says, "this is the heart doctor with heart." Alternatively, your medical assistant logo could say something like, "I give medicine a human touch."
Remember that your logo can also be designed to appeal to a specific demographic. A physical therapist's office may choose an athletic design to represent their focus on sports-related injuries. Meanwhile, an OB/GYN may use colors and symbols that appeal to their patients' femininity.
