The DENTAL STUDIO SF Team

Laura DeGrassi, Registered Dental Hygienist

I have always been fascinated by the human body. I started working in a children’s dental office at the age of 15 and put myself through college, dental assisting along the way. I graduated in 2007 with my bachelors of science from the University of the Pacific’s School of Dentistry.

I have been blessed to be the hygienist here since 2008. I truly love my job and I’m proud of our amazing practice. You’re not just a mouth here; you’re family.

Dr. Cornehl has always been on top of the newest advancements in dentistry and encourages us as a team to bring that education and skill back to our patients. We are dedicated to helping you achieve an overall healthier life!

When I’m not saving the world from gingivitis, I enjoy staying active, trapeze, traveling, and time with my family, friends and dog Brodie!

Heather Mahan, Registered Dental Hygienist

Originally from Chicago, I’m still trying to decide West Coast best coast or Midwest is best – I love both!

When I was a freshman in college, I decided to pursue a career in dental hygiene. I was unsure of which major to pick and I had my own dental appointment (which I always loved going to – is there a better feeling than clean teeth?!). The hygienist was so patient with the million questions I asked, and I thought this is totally something I could see myself doing! I’m so glad I did – I love this profession.

I treat every patient how I would want to be treated and I think my expectations of treatment are pretty high! A reason I wanted to work with Dr. Cornehl – someone else who has high standards. Not only have I been in private practice for a decade but have 3 years of instructing dental hygiene students. Teaching requires you to be up to date with all the new research and standards.

In my free time I love trying new exercise classes, hiking, traveling and exploring parts of the city – usually based on restaurants!

Maria Hernandez, Registered Dental Assistant

My name is Maria, and I have been in dentistry for over 28 years. I am the first member of Dr. Cornehl’s team, beginning in 2006 as his assistant. It has been a great pleasure watching the practice grow while building on the skills I’m passionate about. It’s rewarding for me to play an integral part in helping our patients to achieve their dream smile. For fun, I enjoy sports and spending time with family.

Reem Teclebrhan, Registered Dental Assistant

As a child, I remember going to the kitchen grabbing spoons and forks pretending they were my dental instruments. I would fill empty plastic bags with water and salt tie a knot- creating an IV drip and play doctor with my siblings. I have always wanted to get into the field of medicine. As I got older, my passion for people and medicine grew. I became more and more fascinated at how marvelous the human body is, and how every feature is intertwined. I applied for dental school in Ukraine for that very reason.

After graduating in 2016, I embarked on a journey to the United States to obtain a higher education and I started by taking courses to become a dental assistant. Dentistry embodies two of my very favorite things: art and medicine. It is my solace. I feel tremendously blessed to be a part of such an impeccable dental office.

Dr Cornehl is up to date with the latest advancements in dentistry and his office provides an environment where patients are an active part of their treatment. It is great to be surrounded by professionals that have an ongoing drive to grow in their respective careers. There is never a dull moment!

In my spare time, I enjoy cooking, traveling, being in the great outdoors, working on my physical fitness and watching forensic documentaries. I am trilingual ( I speak English,Arabic and Russian) and currently working on adding Spanish to the list!

Cathy Buenafe, Front Office Administrator

My name is Cathy and I am the friendly face at the front desk! I have been providing customer service for more than 7 years.

I am happy to answer your questions, plan your appointments, help resolve concerns, make your visits a positive experience, and will assist you in explaining and discussing your insurance benefits and processing dental claims.

It is truly a blessing to work with Dr. Cornehl, who genuinely cares for and respects his patients and employees. We are staffed with people who really understand the meaning of teamwork and everyone works as hard as they can to create an organized, enjoyable, and welcoming workplace.

In my spare time I enjoy being outdoors, especially in the summer, and love spending time with friends watching movies and basketball games.
