Dr. Dena, owner of Peninsula Hearing Center, is a native San Diegan. She has worked with the hearing impaired for over fifteen years and prides herself on continuing the care of the community she calls home. Dena’s experience includes a variety of healthcare settings including private practice, hospitals, clinics, and as an educational and occupational Audiologist. She has the capability to properly assess any individual’s hearing needs no matter their age, budget, lifestyle, or type of hearing loss.

Peninsula Hearing Center is conveniently located in the village of Point Loma, with a friendly, knowledgeable, full-time staff. The staff shares a community focus, which is enhanced by Dena, who remains active in the Point Loma Association and Coronado Rotary. With this home-grown, professional expertise, Dena and her staff can accurately develop a healthy hearing plan to improve the quality of life for every patient that walks through the door. Now more than ever is a great time to hear what you’ve been missing.
Besides a beautiful private practice in Point Loma, Dr. Dena opened Coronado Hearing Center in March 2014.

Personally, Dena enjoys spending time with her husband, two daughters, and three dogs. Taking part in all Southern California has to offer, she loves taking her dogs to OB Dog Beach, running, swimming, hiking and riding bicycles with her family. Dr. Dena Riso, Au.D. is a licensed Doctor of Audiology and certified Hearing Aid Dispenser with the state of California.

Dr. Gemma Gray and her family (including their dog!) moved to San Diego in the summer of 2019 from the UK. Gemma completed her Masters at the University of Southampton and her Doctorate was through the University of Florida. She has been an audiologist for 12 years+ and previously managed a large team of audiologists for a private hearing care company in the UK. Gemma works here Tuesday through to Thursday and we are excited to work with her as she complements our ethos of patient-centered care. This is at the heart of everything she does and she looks forward to addressing your hearing concerns so you can live life to its fullest.

When Gemma is not working, she is usually hanging out with her two young daughters, husband, and pet whippet, Dakota. They moved here to San Diego for the sun, and so you tend to find them outside exploring the area, hiking up a mountain, or playing at the beach.
