All professionals at Howard Pack DMD PC maintain the highest levels of accreditation and pursue ongoing education to stay abreast of the latest trends in the medical field. Read on to learn more about our staff's experience and training.

Howard H. Pack, DMD

Howard was born in Los Alamos, NM and is a child of the southwest. He received a business degree from Brigham Young University in 2005 before attending dental school in Cleveland, OH. He graduated from Case Western Reserve University School of Dental Medicine in 2009, after which he did an Advanced Education in General Dentistry residency at the University Hospital of Cleveland. He strongly believes in continuing education and is constantly striving to improve himself as a dentist. While in Cleveland, he met his wife, Whitney, who was also in school training to become a pediatrician. She also was from the west and both were eager to move back after finishing their professional training.

Following residency in 2010, he and his wife Whitney moved to Durango and began their respective practices. Howard quickly began looking for something in Cortez, and purchased this office in 2011. They moved to Cortez after a year in Mancos. Whitney is a pediatrician and has opened her own clinic here in Cortez. They have two children with a 3rd on the way. Trent is a busy 5 year old and Lexi is a sweet 3 year old. They love the area and are happy to live in such a beautiful place.

Cerissa Darling-RDH

I received a degree from Colorado Northwestern College in 2003 and have been with the practice as a full time hygienist for over 16 years. I was born and raised in Pleasant View and love the people and outdoor activities the area has to offer. My husband is part owner of the Kokopelli Bike Store on Main Street.
I stay up on most current practices and procedures, and take pride in customer care, education and serving the patient. My favorite part of my job is building relationships with my patients.

Sarah Williams-RDH

I graduated with a bachelors in Dental Hygiene in 1990 from NAU in Flagstaff, and have been working in private practice for over 29 years. You may find me at the local Children's health fair and working in our local schools, where I provide dental screening and education.
All my patients become my friends and I enjoy developing a trusting relationship. When not busy with dentistry, I enjoy spending time with my daughters, pets and friends.

Cheryl Sheek

I joined the practice 6 years ago, having 22 previous years of experience assisting and managing the dental office. My husband is 5th generation cattle ranching in the Mancos Valley. There, we raised five boys and are still active in ranching business. Twice a year, I travel into southern India to work at a mission home, providing dental and medical care to 200 children from poverty situations. In our office, I will be staying on top of your insurance claims, helping you understand your benefits and working out financial plans for your treatment options.


I am a new Colorado resident originally from Dallas but for the past 5 years I was living in Savannah, GA. My parents have lived in Colorado for the past 10 years so I moved here to be close to family. I am married with a bunch of furbabies. I love the outdoors, hiking, riding bikes, camping and just taking our dogs down to the river. I have been in the dental field since 2009. I love working in all fields of dentistry. I took break from general and went into Orthodontics for several years but I'm happy to be back in general dentistry. I love meeting new people and seeing the outcome of their new smile. I am looking to forward to meeting you in the future.


I have been with this practice since December 2017 and sit chair side with Dr. Pack as his assistant. I received a certificate of completion as a "Certified Dental Assistant" in February 2018. I am a mother of two boys and just recently got engaged. I love spending my free time with my family. We all love going bowling, to the movies and just being with one another. I also love playing sports, softball being my favorite.


I am from Albuquerque NM, where I graduated from Pima Medical Institute in 2010 for Medical Administration. I am experienced in Mental Health and Primary Care, but I am very excited to join the Cortez Dental team and gain experience in the Dental Field. I decided to move back to the area to be close to my daughter and grandsons. I enjoy spending my free time with my family and friends.
