About Us

I take pride in sharing my love and respect of animals with my students. I teach students not only all the basics of pet styling (ie: breeds, breed specific patterns) ,I am also sure to spend a considerable amount of time concentrating on the refinement of scissoring and finishing skills. I strongly believe that this aides our students in strengthening their ability of finding immediate work upon completion of course.

*Most established grooming salons are quite busy. They reach a point in the growing development of their business when they will find it beneficial to add an additional groomer to the staff. They do not have the personal time to "shadow" and oversee every aspect of a new groomer employee. They are interested in hiring a confident Groomer . One who is capable of working independently and immediately with minimal supervision. Understanding of course, nothing substitutes for experience, my goal, is that the GTC student will be able to, with assurance and confidence, fill this position.

Students have traveled near and far ( ie: PA, MD, WI,NY …) to reap the benefits of earning a Groomer Training Center Diploma! 

Mission Statement

To hold the title of Certified Professional Dog Groomer to a deserving high standard of professionalism. To instill pride in those who practice the art. To raise public awareness of the skill, creativity and dedication needed to execute even the simplest of everyday pet grooms.
