Melissa Nava


I’ve been with Dr. Nicosia’s office for 12 years as a dental assistant and office manager. I make sure every patient feels at ease by building confidence, trust, and friendship with each of them. I am constantly learning more about dentistry every day and sharing with our patients so they can better care for their oral health. Our staff work’s extremely well together to provide the best service and experience to our patients. I enjoy spending time outdoors with my family.

Ann Morales

Business Assistant/Treatment Coordinator

I was born and raised in Los Angeles, CA and have lived in Houston for the last 17 years with my husband and daughter after having served in the United States Marine Corps. I have worked with Dr. Nicosia for over 10 years and I am passionate about patient care and their dental needs. I am always eager to assist patients with scheduling and treatment plans and provide much needed support in the front and back office.

I’ve been a dental hygienist for 13 years and joined Dr. Nicosia’s practice in 2013 when I moved from my hometown in Port Arthur. I strive to provide the highest quality of care to help patients obtain their optimum oral health while at the same time focus on their comfort. I enjoy traveling and spending time with my family in my free time.

Maricela Hernandez

Registered Dental Assistant

I began my dental career 10 years ago working with Dr. Nicosia and his staff. Dr. Nicosia has taught me the fundamentals of assisting, but also taught me the importance of treating our patients like family and making sure that your visit here can be the best visit possible. I couldn’t imagine working for a better dental office, and I am grateful for the opportunity to work with such caring people.

In 2002 I joined Dr. Nicosia’s dental family as his surgical assistant. A few years later I became his Hygienist. He has mentored me to be the best hygienist I can be, to always provide the golden standard of care and the importance of patient education.
