MedSpa by CT Derm

The MedSpa was established to safely satisfy our clients’ desire to have access to procedures that would improve their overall appearance. Chemical peels and various laser treatments had been offered for several years at CT Derm, mostly for the treatment of skin disease. So it was natural, with the advancement of medical esthetics, to act upon our clients’ request and deliver a full service Medical Spa that would put equal focus on exceptional results and client education. With the inception of the MedSpa, Dr. Thornfeldt has established a team of professionals that are ready to help you with your skin care concerns.
