About Hyperbaric Centers of Southwest Florida

Who we are. Why we do what we do.

Hyperbaric Centers of Southwest Florida was opened as a result of the emotional journey our family has taken in caring for our son and mother. This is our story in a nutshell.

I (Elly) am a mother. Imagine your child, whose behavioral issues you struggled with for years, and the battles you face together; and when seeking help from doctors, psychiatrists, psychologists, counselors, therapists, teachers, pastors, (everyone!) you are told your child has ADHD, ODD, OCD, and that he/she will either be dead or in jail by the time they are 18 years old. Medications don’t work and a special diet doesn’t either. What do you do? Add to all of this the discovery that your child has a Traumatic Brain Injury (TBI). Now what do you do?

I am also a daughter and caregiver. Imagine you find out your mother has cancer. She endures multiple surgeries requiring strong anesthesia and pain medications, then experiences several minor strokes, all of which affect her memory as well as her ability to walk, talk, and perform simple day-to-day tasks. She then breaks her hip and has hip replacement surgery. What do you do?

Our discovery of Hyperbaric Oxygen Therapy was a breakthrough for our family. While there may be only 14 FDA “approved” indications, with a physician’s order, numerous other “off-label” indications such as: TBI, the effects of stroke, and many more can be treated as adjunct therapies.

Our experience compelled us to open Hyperbaric Centers of Southwest Florida because we understand the pain and stress families and individuals go through as a result of the struggles associated with supporting affected children, parents, and other family members, as well as the struggles of those family members themselves. We understand the challenges of being a caregiver. However, we also understand and have experienced the joy that comes from a son telling us that he can think more clearly than he ever believed he could, and from watching a mother miraculously walking, talking, doing word puzzles and helping out around the house. These are all things I never could have imagined happening, and we want to give more people and families the same opportunity, while at the same time improving the quality of their lives as well as the people who care for them.

My (Elly’s) mom, Penka, has overcome cancer, experienced minor strokes, and has had a partial hip replacement. The anesthesia and pain medications associated with these events left her struggling to walk, unable to remember many things, and she had great difficulty speaking which led to her almost never talking at all. She needed a great deal of day-to-day care. Since completing the last round of treatments she has become very independent. She speaks much more often, works on word puzzles, and her memory is improving. More treatments are certainly in her future. “Thank you!” from the Atanasova Family


I am Bob and Elly’s son, and I was diagnosed with a TBI (Traumatic Brain Injury) that was affecting my ability to remember and make decisions. Often, as soon as someone had an idea, I would be off and going without even thinking about it. A SPECT (Single-Photon Emission Computerized Tomography) scan identified “moderate” abnormality of both of my cerebral cortices, greater on the right than on the left. After 40 treatments, there was a significant improvement of function in both cerebral cortices. I have completed 100 treatments to date, and I can now think much more clearly!

Bob & Marie

Bob and I have had a great experience with our hyperbaric treatments. Both Elly and Bob were so understanding, kind, considerate and helpful. As it turned out, both Bob and I had many special needs and needed a great deal of individual attention. Both Bob and Elly went way beyond what could be expected of them to help us through the treatments. With so much love and caring, they helped us every step of the way.

I found out that the very bad pain I was having in my back became less of a problem. My poor digestion (I have chronic pancreatitis) is much better than I thought possible. I have more energy and better tolerate exercise. Bob had so many problems that were incurable, but even he showed some improvement. We plan to go back for more treatments. Thank you Bob and Elly - Marie and Bob Slauson

I spent an extensive amount of time at this facility for hyperbaric treatments. I was treated as family with the utmost respect and courtesy. It is clean, organized and safety is of the greatest priority. I look forward to continuing healing and will not hesitate to go for treatments in the future.


I had a wonderful experience at Hyperbaric Centers of Southwest Florida. The team was very patient with my parents during their treatments. They have a strong passion for not only treating their patients but educating them about HBOT overall. I would highly recommend their center.
