About me

Hello! My name is Diahn (pronounced Deeon). As a licensed and certified speech language pathologist (SLP) with 30+ years of experience, my journey as an SLP started in an unexpected way. During my high school years, my best friend experienced a brainstem stroke, resulting in unilateral paralysis and laryngectomy. After witnessing her communication challenges, unbeknownst to me at that time, the seed for my speech pathology career was planted. In 1991, I obtained my Master of Science degree at James Madison University and my SLP journey began. To date, my experience includes, but is not limited to, treating early language delays, autism, apraxia of speech, articulation disorders, stuttering, and adults with professional communication needs. I enjoy working with all ages and strive to keep my clients' interests in the forefront of therapy. From play-based activities for little ones, science experiments with older children, to career communication scenarios with adults, my aim is to help each client achieve their personal goals within a fun and motivating therapy environment.

Other interests

Dogs, the beach and being in nature are definite ways to get me smiling. I adore being swept away while writing about and taking photos of dogs and the coast! My husband, two pups and I love to travel and we always look forward to hooking up our trailer for true camping relaxation.

My granddaughter liked forward to her session and seemed to enjoy it. She seemed to pick up what was asked of her fairly well also.

My son loves Ms. Diahn and his speech has gotten so much better since starting with Expressable. Diahn helped us determine some irregularities and after surgery we're hoping that his speech improves even more.

My husband and I were amazed at how well Diahn engaged with our toddler virtually - he LOVES her.

Diahn is a wonderful speech therapist! Our son has greatly increased his vocabulary, articulation, and overall speech with her assistance. We love being able to be involved in his sessions and help him implement the techniques he is learning into everyday life. Diahn is knowledgeable and motivating. And she manages to keep our son consistently engaged, which is not always an easy task with a six year old! We look forward to continuing our son's speech journey with her. I recommend Expressable to everyone who has concerns about their child's speech!

We are LOVING Expressable and Ms. Diahn. Absolutely loving. I’ve recommended you guys to numerous friends. Ms. Diahn makes sessions fun for my 7-year-old while continually ensuring he’s making fantastic progress with his speech. She’s so nice and makes him so comfortable. I love how she teaches him and helps him learn awareness and self correction - all while keeping things light, positive and empowering. It’s been amazing to watch and hear my son progress. He’s so proud of himself and he looks forward to his sessions. We couldn’t be any happier. Thank you for an awesome platform and for our incredible therapist!
