I am proud to be both the owner and Clinical Specialist here at Cobalt Therapy. My first position after graduate school was with a large level-two trauma center in Southern California. There I was able to work with mentors and other professionals who had extensive backgrounds in the medical field. The skills and certifications I earned through the guidance of my more experienced colleagues provided a strong foundation for my work.

My role at the hospital involved performing extensive diagnostic procedures such as Modified Barium Swallow studies and Flexible Endoscopic Evaluation of Swallowing. In addition to this, I conducted medically complex treatment programs. To this day, I thrive on deepening my expertise. I’m particularly fascinated with the emerging technology in this field, and how we can apply it toward major advancements in speech-language pathology. I’m eager to make a lasting contribution to my field in diagnostic assessments and therapy programs.

I am a licensed Speech Language Pathologist, born and raised in sunny Orlando, Florida. I graduated from the University of St. Augustine with a Master's in Science. My journey led me to a fulfilling role at a Traumatic Brain Injury (TBI) center, where I've had the privilege of working closely with individuals navigating the complexities of communication disorders stemming from brain injuries.

At the TBI center, I honed my skills in assessing, diagnosing, and treating speech and language impairments caused by traumatic incidents. I collaborated with interdisciplinary teams, including physical therapists, occupational therapists, doctors, nurses, aids, and psychologists, to provide comprehensive care tailored to each patient's unique needs. My time there has equipped me with invaluable experience in addressing a wide range of speech and language challenges, from aphasia to dysarthria.

Now, as I embark on this new chapter, I bring with me not only my clinical expertise but also a deep understanding of the resilience and determination exhibited by those on the path to recovery. I am eager to apply my knowledge and skills to make a meaningful difference in the lives of individuals I will encounter in my new role, enriching their communication abilities and empowering them to overcome barriers with confidence and grace.

I am a certified and licensed speech language pathologist who has worked in the field for almost 10 years. I received my bachelor’s degree in psychology from the University of Central Florida in 2007. While taking graduate classes in cognitive sciences, I took a class in Aphasia (an acquired language disorder) and was immediately fascinated. I then applied to the communication sciences and disorders program, completing my master’s degree in 2013. I have worked with adults since that time, with my passions being in the rehabilitation of communication, cognition, and swallowing. My certifications include the Lee Silverman Voice Treatment and the McNeill Dysphagia Treatment Program, and I am consistently pursuing further education and certifications to advance my skills and strive for effective therapy for my patients. I am honored to be a part of the Cobalt Therapy rehabilitation team and look forward to providing modern and up-to date treatment and patient-centered care.

Speech and Swallow Therapy in Lake County, Florida

Cobalt Therapy is the only private practice that is exclusively speech therapy for adults living in Lake County, Florida. We offer therapies that target improvement of thinking skills (cognition), communication abilities, voice and swallow function. This includes advanced swallow therapy with services that utilize electrical-stimulation for improving muscles needed to swallow safely. We also provide a variety of effective voice therapies, such as LSVT Loud for Parkinson’s disease.

We are a privately-owned, speech-language pathology service. Our compassion-driven vision is based on the growing need for qualified medical speech therapists to serve the Lake County area. In addition to our outpatient and in-home services, we also provide staffing support for healthcare facilities.

The bird in our logo is a swallow, which is very common in this beautiful part of Florida. Swallows are deeply linked with new beginnings and the renewal of life. They are considered beautiful and delicate birds, bringing good news to those who see them fly by. And hey, let’s not forget the name of this bird …it’s one of the things we treat best!

The color cobalt has a strong connection with nature and is considered to be soothing, peaceful and trustworthy. We strive to embrace all of these qualities when we work with you.
