Currently, I reside in Mesa with my beautiful wife Vikki, and our two amazing children Axel and Dylan. In our free time, we love to enjoy local sporting events and spend time outdoors.

I completed my residency at an E.N.T. clinic in Tucson, Arizona before moving to the Phoenix area. My husband and I had our first child, our sweet little boy named Madix, in August 2017.

I completed my undergraduate education with a focus in Public Health from Northern Arizona University in 2014, and my Doctorate in Clinical Audiology (Au.D.) from A.T. Still University in 2019. I have a passion for providing holistic care and strive to give my patients excellent treatment through current evidence-based practices and knowledge of current technology.

Jessie Penkoff, Au.D. – Doctor of Audiology, CCC-A

I am originally from Mesa, Arizona but resided in Tucson, Arizona for the past seven years.  I graduated with my B.S in Speech, Language, and Hearing Sciences in 2015 with my Doctorate in Clinical Audiology in 2019, both from the University of Arizona. I am also a member of the American Speech-Language-Hearing Association. Although I loved living in Tucson and miss my friends dearly, I am happy to be home! Patient care means everything to me as my mother had sudden onset single sided hearing loss. I take pride in knowing that I was able to fit her with hearing aids, and I look forward to bringing that same amount of joy to the many individuals who walk through the door here at Advanced Hearing Group. When I am not working with patients, I love spending time with my dog Gemma in the great outdoors, or in the gym lifting weights.

Office Manager:

Mauricio Plata, Patient Care Coordinator in Scottsdale

I have been a Patient Care Coordinator at the Scottsdale offices since 2016 and now manage the office. I am fluent in both English and Spanish. I was born in Hidalgo, Mexico, but I have lived in Arizona for most of my life. In my free time, I enjoy traveling, spending time with my girlfriend and my family. I’m really passionate about exploring new places and being adventurous.



Jaci Gillispie, Patient Care Coordinator in Mesa

I am an Arizona native, and I’ve been with Advanced Hearing Group since 2016.  I began working for Advanced Hearing Group after moving from my small hometown in Southern Arizona where I worked for a shipping company for over two years. It’s safe to say that while I didn’t have a background working in the medical field when I joined Advanced Hearing Group, I did have a strong customer service background. That background prepared me to learn that I thoroughly enjoy working with patients and helping them with all of their needs. I am now am pursuing my education in healthcare. I recently married my high school sweetheart in early 2017 and my husband and I hope to one day own our own funeral home as my husband is studying mortuary science.  In my spare time, I love to go shopping, bake delicious goodies, go camping, and spend time with family and friends.

We also have a little dog that we truly love, Cosmo.  I enjoy spending time with my family, watching movies, and truly love fast muscle cars.

Happy Patients:

We want to thank Dr. Johnson and the staff at the South Scottsdale office for their prompt service when I had a problem with one of my hearing aids. They saw me within an hour of my call to their office, and resolved the problem in a few minutes. We appreciate a business that is so helpful and caring.

As a person who was just diagnosed with tinnitus and some hearing loss, I decided to see Dr. Gary Johnson and discuss if hearing aids would be beneficial to me. Dr. Johnson gave me a thorough examination and evaluation and recommended hearing aids for me to help with the hearing loss and help quiet the tinnitus. I have been wearing my new hearing aids for about 2 months now and I am so happy with them.

Dr. Johnson did a wonderful job evaluating what would work for me. He is very pleasant, listens to the needs of the patient, answers all questions and makes you feel very comfortable. I have been helped with the hearing aids for both my tinnitus and hearing loss. Don’t hesitate to go see Dr. Johnson if you are in need of someone who can help with your tinnitus and hearing problems. He is the best in the business.

I had a hearing aid quit on me. I went into the Mesa location and was greeted by a pleasant young lady and was promptly helped to get my hearing aid working again. And there was no charge!! Great service and pleasant staff. What a great experience!!
