Meet Our General/Cosmetic Dentists
Dr. Bonnie Morehead
I have enjoyed practicing dentistry in Manteca for over 25 years. I grew up on a farm in Lockeford, California, and have spent my life here in the Central Valley. I attended The University of the Pacific (as did my two daughters) where I joined a community service sorority and am still active with my chapter. I attended the University of Pacific, now the Dugoni School of Dentistry, and I continue to spend time in “The City,” active with the Board of The Pacific’s Dental School Alumni Association. I enjoy being active in my community, church and in the San Joaquin Dental Society where I am a past President. I also enjoy gardening, travel and spending time with family and friends.
Knowing that many people are fearful of dental treatment, I undertook certification training in DOCS and Oral Conscious Sedation. These techniques allow my patients to receive care in a very relaxed environment while getting complete dental care. I have extensive training in cosmetic dentistry, root canal treatment, implants and complete dental rehabilitation. I have a passion for patients’ well-being and enjoy working with my staff at Valley Oak Dental Group to help my patients reach their esthetic and health potential. I have the ability to do beautiful, metal free crowns in one visit with the use of “CEREC” technology. My goal is to provide kind, respectful and understanding attention to your dental needs in a friendly, relaxed environment. New patients are welcome.

Dr. Joseph then attended the University of California at San Francisco Dental School where he graduated in 1995.
Following graduation, Dr. Joseph joined Valley Oak Dental Group, returned to the central valley, and married his lovely wife, Nisha. Together they are raising sons Tobias and Kaiden. When he isn’t at the office, Dr. Joseph enjoys time with his family, music, and playing his bass guitar.
Dr. Joseph’s goal is to provide a gentle, caring environment in which to assist patients achieve a healthy and happy smile.
Dr. Rudy Ciccarelli
Dr. Rudy Ciccarelli attended Marquette University in Milwaukee, Wisconsin, and Creighton University in Omaha, Nebraska where he majored in pharmacy. He then graduated from the University of Pacific School of Dentistry and in 1987 settled in the central valley where he was born and raised.
Dr. Ciccarelli enjoys the outdoors including camping, bicycling and water sports with his wife, three sons, and young daughter.
In practice, Dr. Ciccarelli’s passion for dentistry goes beyond his clinical skills and extends to his patients’ physical and emotional well-being. As much as possible, he tailors his dental service to accommodate his patients’ needs and wants.
Dr. Elizabeth Grecco
I grew up in what used to be rural north Modesto and, with not much else to do, I spent a lot of time following my dad around while he made repairs to the house, yard, machinery, and cars. I grew to appreciate the sense of satisfaction we got from restoring things back to function, and I still really enjoy problem solving and fixing things, both prerequisites for the technical side of dental practice.
I attended Modesto Junior College and graduated, with honors, from the University of California, Santa Cruz with a Bachelor’s degree in Biology. I received my dental degree from the University of California, San Francisco in 1990. After graduating, I undertook further training at the VA Medical Center/University of California, San Francisco in the General Practice Residency program. I have been practicing at Valley Oak Dental Group since 1993.
I am very grateful to live in this beautiful part of California because I enjoy pretty much anything that involves being outdoors including gardening, biking, hiking, and swimming. I also enjoy cooking and traveling with friends and family.
I am committed to providing high quality care to my patients in an environment of trust and confidence as well as comfort and satisfaction. I hope to provide the best that modern dentistry has to offer while respecting the needs and desires of my patients.
I am a member of the American Dental Association, California Dental Association, and San Joaquin Dental Society.

Meet Our Children Dentists
Dr. Mohammad El Farra
Being born and raised in North Hollywood, California, I obtained a Bachelor’s degree in Exercise Physiology in 1999 and my dental degree in 2003—both from the University of Southern California (GO USC TROJANS!). I relocated to Manteca in October 2003, when I joined Valley Oak Dental Group. My lovely wife Hadeil Kotb (who is a doctor of Physical Therapy) and I have three wonderful children—daughter Yasmeen and sons Idrees and Kareem. I am actively involved in our community and sponsor various activities and organizations that promote life-enriching programs for our youth. I enjoy spending time with my wife and kids, being actively involved in my religious community and anything involving the ocean and FOOTBALL!
I limit my practice to infants, children, young adults, and those with special needs. I strive to keep current with the leading edge techniques, materials, and equipment that will allow me to provide the highest quality of care. I have completed course work and maintained, through continuing education, my certificate in Oral Conscious Sedation. I am an affiliate member of the American Academy of Pediatric Dentistry, and an affiliate member of the California Society of Pediatric Dentistry, the American and California Dental Associations and the San Joaquin Dental Society. I am also a member of the Special Care Dentistry Association. For your child’s safety and your peace of mind, I am certified in Pediatric Advanced Life Support and CPR. I continue to pursue continuing education in the fields of root canal therapy, cosmetics, sedation, and general patient health.
I enjoy providing the best possible dental care to my patients—but I always make the connection between dental health and overall health. I am an ethical and quality-oriented dentist who is determined to provide a comfortable and fun-loving environment for your child’s first and future dental experiences. My patient’s oral healthcare is my top priority and I will always be committed to providing my parents with the information they need to make good, sound decisions regarding their child’s life-long dental health.
I look forward to meeting you and building a lasting relationship with you and your family.
