Dr Gregory Cook

Gregory A. Cook DDS

After growing up in then rural Brecksville, Ohio, I graduated from Albion College in 1969 with a BA in Physics. I married my lifelong friend, Marianne, upon graduation. After attending the University of Cincinnati in Design, Art and Architecture, I spent five years as a city planning consultant and systems analyst. When our first daughter was born, I felt the need for a career change. I had a wonderful dentist at the time and Dentistry was a good fit for my abilities in both science and art. I attended Case Western Reserve University School of Dental Medicine and graduated in 1979.

After 20 years of private practice in Mayfield Heights, I reinvented my practice by moving to Beachwood and, along with my entire staff, completed a year externship and surgical training at the Midwest Implant Institute (MII) in Columbus. Having published in the Journal of Implantology and having completed numerous implant cases, I was recognized as a Fellow at MII in 2009. That year we purchased CEREC, a Cad Cam porcelain milling system and completed training to begin providing single appointment crowns and onlays for our patients.

In 2019, we purchased a digital panoramic and cone beam (CT) scanner. The improved diagnostic q

uality of our 3D digital images will greatly enhance our implant planning and cancer screening. At the same time we added all new computers in the front office and dental operatories in order to implement a new practice software so that we can become paperless. Every year I become more enthusiastic about my profession and our practice which I named Beachwood Contemporary Dentistry for obvious reasons.

My wife of 50+ years, Marianne, a former OB nurse, keeps busy as a school nurse in the CHUH schools. We are avid golfers, gardeners and walkers. I enjoy training for an occasional 5 or 10K race. We like to travel to visit our two daughters, Amy in Seattle and Amanda’s family in Boulder. She and her husband are raising our two grandsons, Finn and Jack. Their visits to Ohio prompted me to build “Bompa’s Treehouse,” in our backyard which has been featured in Cleveland Heights Walking Garden Tour.

I graduated from Brush HS and later married and raised three children while working as a legal secretary. I joined Dr. Cook’s practice as a chairside assistant in 1997 and later became his office manager. I am very active in my church. I enjoy country living in Newbury with my husband, Paul and my two sons. My daughter’s marriage has blessed us with two grandchildren whom have been a source of great joy for us.

A native of Solon, Ohio, I graduated from high school in 2000. After high school, I knew that I wanted to go into the medical field and Dental Hygiene was very appealing. I graduated from Cuyahoga Community College in 2004 with an Associate degree in Dental Hygiene. I continued my studies to complete a Bachelors degree in Business Administration from Capella University.

Dental Assistant 

After high school in Willoughby, I attended and graduated from Cleveland School of Dental and Medical Assisting. I joined Dr. Cook at his Hillcrest office in 1991 as his dental assistant. My son, Rob, was born soon after and my family moved to our home with 23 acres in Trumbull Township. I followed Dr. Cook to Beachwood, despite the lengthy commute and have been with him over 20 years.

I enjoy the special training I’ve received in implant surgery and CEREC technology. I keep current with continuing education to remain a CDA (Certified Dental Assistant). I’ve gotten to know and shared many a laugh with our many loyal patients. My husband, Bob and I enjoy our country home and our hobbies of motor cycles and “muscle cars.”
