“It amazes me where life can lead you. I began my adult life as a business major and years later am in this position where I can make a real difference in people’s lives. When I’m not working, I enjoy spending time with my wife, Dawn, and rescue dog, Taffy, here on Galveston island. I also love traveling and sailing my boat on Galveston Bay and the Gulf of Mexico.”
Michelle Hruska, PA
Michelle begun her career caring for patients right after high school when she joined the US Navy as a Hospital Corpsman. After four years of active duty she continued her service to this country in the active Naval Reserves for six more years. During this time, she earned her undergraduate degree, a Bachelor of Science in Neuroscience from The College of William and Mary in Virginia. She utilized that degree by working in academic research conducting studies pertaining to fetal alcohol syndrome and cancer. After more than a decade of living abroad and across the United States, she moved back home to Texas to be near family. While taking some time to evaluate her next academic goal, she worked as a critical care tech in a local emergency department to gain even more clinical experience.
She then attended the University of Texas Medical Branch in Galveston and earned her Master ’s degree in Physician Assistant Studies in 2009. After earning her postgraduate degree, she practiced emergency medicine for nearly a decade in the Clear Lake area with the same physician staff that encouraged her to work towards that degree when she was just a tech. Michelle now looks forward to using her knowledge and skills to help care for the patients in the Affinity Immediate Care community.
Michelle currently resides in Galveston, TX. Her hobby is Traveling. Anywhere. Anytime.
“Travel changes you. As you move through life and this world you change things slightly. You leave marks behind, however small. And in return, life – and travel – leaves marks on you.”
Josh Clark, PA
Joshua Clark has spent most of his adult life honoring the skills of Army LDRSHIP (Loyalty, Duty, Responsibility, Honor, Integrity and Personal courage). He enlisted in the Regular Army in May of 2001 and served in various positions before ending his active duty career in Alaska where he transitioned to the Alaska Army National Guard as a medic in 2008.
Joshua attended IPAP at Fort Sam Houston, TX and is a 2016 graduate of the Inter-service Physician Assistant Program (IPAP) through the University of Nebraska.

It is designed to prepare graduates for the unique intensity of practicing medicine in a deployment environment providing compassionate care and making calm, accurate decisions under pressure. The credo of discipline, diligence, and adaptability instilled in him through the military prepared him to thrive in the challenging and dynamic role as a PA-C in the Army, and Urgent Care.

Johnna Cacace, FNP
Johnna Cacace, earned her Bachelor of Science in Nursing (BSN) from Prairie View A&M University. She currently works at an ER; this is her part time job (but she says she loves it just the same:) I believe working at an Urgent Care gives me the opportunity to treat many aliments, but with less stress then the ER setting. Working at Affinity Urgent Care provides easy access to quality healthcare in ‘your backyard’ for those times when your PCP is unavailable or closed. Besides, it’s what I do for a living … you know the saying “if you love what you do, you never work a day in your life”.
I wanted to do something that was challenging, interesting and made a difference in people’s lives. Also, I love the variety in the routine.
Johnna currently resides in Galveston, TX and some of her hobbies are spending time with family and traveling.

Catelyn Knowlton, FNP
I obtained my Master of Science in Nursing from the University of Texas at Arlington, my specialty is family practice. I have been practicing as an NP since 2017. Prior to that I worked as an RN since 2012. I Began practicing as an NP in the Emergency Department right out of school. I am thankful for my time in the ED, although it was very challenging for the three years I spent there I gained irreplaceable knowledge and experience; as well as giving me the confidence to now practice solo in the urgent care setting. I transitioned out of the Emergency Department at the beginning of 2021 after a long and tiring year of COVID havoc.
I was lucky to have been recommended to Affinity by a co-worker who sometimes picked up shifts there. I had my first baby in October and was thankful to have a position to start once my maternity leave ran out. I have enjoyed having a closer relationship and follow-up with my patients in the urgent care setting as well as serving the community which I live in. I feel we do an excellent job of bridging the gap between primary care and emergency room. At Affinity all the advanced practice providers are truly invested in helping manage what we can safely do for our patients. I am so lucky that my work-life balance at Affinity allows me to do that.
Catelyn currently resides in, TX and some of her hobbies are working out, being outside, being with family and hosting get-togethers with friends…
The best advice I ever received is “listen to the patient, they will tell you what’s wrong with them”. To all my patients at Affinity, I am here to listen and get you better!
