My husband and I found Dr. Tysinger through a friend's referral, and we were extremely pleased with our experience. Dr. Tysinger and the entire staff at PREG were attentive and thoughtful throughout our fertility journey, patiently answering all our questions, including those arising from our anxiety and concerns. From the first day, we knew that choosing PREG was the right decision. We felt heard and cared for here. I sincerely recommend PREG to anyone considering fertility treatment!

I would recommend them 10,000 times over. My husband and I tried to conceive for 10 years 🫣. We had IUI at another fertility clinic, but the results were not ideal. Then I came across PREG and made an appointment. After meeting Dr. Theisen, he gave my husband and me so much hope. Our first IVF transfer failed, but he continued to reassure us that it would work. We had a second transfer and are now 10 weeks pregnant 🥰🥰🥰. It is unbelievable.

Words cannot express how grateful I am to Dr. Tarnawa and his outstanding team! First, he is truly an excellent listener. He is considerate, kind, and the best IVF doctor I have ever met. He was very patient and understood my family history of blood clots and my salpingectomy. He kept me on a natural cycle without putting strain on my body or compromising my health. He has truly been a blessing to our family. Last Wednesday, February 18, 2026, we welcomed our beautiful son, Aidan, whose due date was February 28, 2026, after a 5-day 5AA embryo transfer. He is healthy and active, weighing 8 pounds 5 ounces and measuring 20 inches. He is absolutely beautiful and healthy! If we pursue IVF again, we will definitely return to transfer one of our remaining embryos. This clinic is beyond wonderful, and they truly feel like miracle doctors. My husband and I previously went through IVF elsewhere, and it was a nightmare. This clinic, doctor, and entire staff changed everything and gave us a wonderful experience!

HIGHLY RECOMMEND! Dr. Tarnawa and Katie were a fantastic team with excellent bedside manner. We felt heard, and Katie was very compassionate. They helped us diagnose and treat a difficult C-section scar defect and endometriosis so we could have our dream baby. We had previously visited another fertility clinic where we felt rushed in and out like cattle. That other popular local clinic made very little effort to address the underlying causes of my wife's fertility issues, and as her husband, they made me feel inferior for trying to understand why we were having fertility problems after conceiving our first child easily. With PREG and its extensive network of doctors, we found and corrected the problem. Overall, we had a great experience at PREG!

Our pregnancy was an emotional journey, and the entire experience was beautiful and unforgettable. From beginning to end, through every high and low, we felt supported and cared for by the medical staff. We will always be grateful to Dr. Tarnawa, Nurse Katie, Nurse Alexis, Nurse Mary, and the entire care team. On February 19, 2026, we welcomed our beautiful daughter.

Update: April 2026: Successful pregnancy and already discussing the next transfer with the same team ❤️❤️❤️❤️❤️
I began my IVF journey with CFS and transferred to PREG after a few years. It was the best decision of my life. Dr. Theisen met with me to discuss my history of miscarriages and what I wanted from PREG, and he fully delivered. The staff are kind and supportive. Whenever I have a question, they respond quickly and without judgment. When I suggested different things I wanted to try, he researched them and worked with me on a new approach. The experience did not and still does not feel transactional; it feels like I have a team behind me working toward the same goal. We tried a completely new protocol and some experimental approaches, and I am now 8 weeks pregnant. I hope the pregnancy continues, but either way, the experience has been amazing. I am sad he cannot also be my OB, but such is life. I cannot recommend PREG and Dr. Theisen highly enough.

Everyone at PREG is wonderful and very kind! Fertility problems are difficult, but Dr. Khader and all the nurses made the process much easier. I would definitely recommend PREG Summerville to anyone needing reproductive care.

We cannot say enough wonderful things about PREG. From the very first appointment, the entire team made what can be an overwhelming and emotional process feel respectful, organized, and supportive - Dr. Tarnawa, Katie, Alexis, Mary, Jennifer, and every kind soul from reception to clinical care are angels on Earth. We will be forever grateful to Dr. Tarnawa (& our nurse Katie!) for his expertise, gentle guidance, and kindness. Dr. Tarnawa took the time to explain options, walk us through each step, answer every question, and truly cared about our journey and us personally. Because of Dr. Tarnawa and the PREG team, we are expecting a baby girl later this spring! We cannot say enough wonderful things about PREG and will always recommend PREG for anyone seeking fertility care. Although we graduated from the fertility clinic, we still talk regularly to the PREG team, and we will be forever grateful for them!

We love PREG Summerville and everyone there! Thanks to them, our first transfer resulted in our daughter in 2022, and we recently had another successful transfer with a mosaic embryo. We owe this to Dr. Tarnawa, who gave us the confidence to keep trying. We drive more than two hours each way to PREG for every visit and are truly grateful to them!

Dr. Carter and team, words cannot express my gratitude for your support and guidance during the most difficult time in my husband's and my lives. You helped us see hope and maintain confidence in science and our medical team. When we finally became pregnant, you responded quickly to our concerns and scheduled ultrasounds and multiple meetings as needed until the pregnancy was safely established. I am in tears as I write this. I was so moved that I decided to move into reproductive endocrinology after completing nursing school. Thank you for everything. We will return when we are ready for our second baby.

Choosing this clinic was one of the best decisions of my life. I was very fortunate to have a successful first IVF cycle. None of it would have been possible without the attentive care of Dr. Tanawa, nurse Alexis, and Jennifer. From the beginning, Dr. Tanawa made me feel safe, heard, and confident. She always explained things patiently and reassured me kindly. Jennifer warmly welcomed me at every visit, and her smile and compassion comforted me when I felt overwhelmed. Alexis was a guiding light throughout, encouraging and uplifting us and treating us like family.
The team’s professionalism, grace, and genuine love gave me strength and hope when I needed them most. I am endlessly grateful and wholeheartedly recommend this clinic to anyone beginning a fertility journey.
Without question, we will choose them again in the future.

Where do I begin? I came to PREG during a very difficult time in my wife’s and my life. The moment I entered PREG and met the staff, I felt renewed hope and happiness. From the first meeting, they explained every process in great detail, which truly reassured me.
When we decided on IUI, I felt endless support and genuine care from people who had been strangers. Yes, I was a paying client, and some might say it was their job—but the care I felt went far beyond that. Special thanks to nurses Alexis and Caroline; they were a blessing! And, of course, thanks to Dr. Theisen, whose kindness and expertise made all the difference.
Thanks to PREG, my wife and I are thrilled to welcome our sweet baby in May 2026 🥲.
If you are considering starting your fertility journey, I highly recommend PREG. They truly make a difficult process feel bright and hopeful.

My wife Jenny and I underwent IVF, and it was an excellent experience for both of us. I want to thank Dr. Tarunawa, Katie, Mary, Christine, Jennifer, Alexis, Caroline, Quinn, Leslie, and Crystal for everything they did. I hope I remembered everyone because each person treated us so well. Dr. Tarunawa was kind, patient, and very attentive. We welcomed our baby girl in late May, and she is the joy of our lives. We would not have her without PREG and the entire staff. You are amazing, and I am grateful we found you.

They once again helped God bless me with another child. Dr. Tarnawa is knowledgeable, patient, and responsible. Katie is the kindest and most encouraging nurse, truly the ideal person to guide you through such a difficult process. Thanks to them and the Columbia team, I had another successful transfer and pregnancy. Thank you for giving me my lovely son. I thank God for leading me to you.

I cannot praise these wonderful people enough. They stayed beside us, and somehow we found true friends, not just nurses. We would not go anywhere else. PREG Summerville is the best. Good luck not falling in love with Caroline, the nurse who reminds you that hope is always there, waiting for you to grasp it.

I cannot say enough good things about PREG in Summerville. PREG was our second choice, and I am glad we ultimately chose it. Driving 4 hours round trip and changing doctors was difficult, but it became one of the best decisions of our lives. Two months at PREG accomplished more than over eight months at an inadequate clinic in Savannah.
Dr. Tarnawa welcomes questions, never rushes, and explains everything clearly. I especially want to thank Katie, the clinic’s registered nurse. She responds quickly and answered my countless questions. She is one of the best nurses I have met. I am very grateful to Katie and Dr. Tarnawa.

My wife and I will always be grateful to the team at Summerville PREG. The entire team was compassionate and did everything possible to support us. We feel very fortunate to have worked with them, and because of them, we now have the family we dreamed of. We would recommend the Summerville PREG team to anyone. You will appreciate their care.

Words cannot express how grateful we are to Dr. Tarnawa, Dr. Immrund, our nurse Katie, and the rest of the PREG team. From the front desk to the finance department, everyone treats you with the utmost empathy and genuinely supports and encourages you. Navigating the uncertainty of infertility is never easy, but receiving the best care certainly makes a tremendous difference. If you are in North Carolina or South Carolina and need a fertility specialist, this is the place to go! We live about 2 hours from the clinic and never hesitated to make the trip for their help. Thanks to their extensive expertise, we welcomed our miracle baby boy in January 2025. He is a gift we will never take for granted, and we will always be grateful to PREG!

Thank you, PREG, for helping us complete our family.
After an unpleasant experience at another fertility clinic, we found PREG and felt incredibly welcomed at our first visit.
Dr. Tarnawa greeted us with warmth, wisdom, and confidence.
Throughout our fertility journey, my experience at PREG felt very personalized. I never felt like “a number being passed around,” but like a person with a unique story. When it was time for my egg retrieval, Dr. Tarnawa even drove to Columbia personally to perform the procedure. The PREG staff went above and beyond every time. Thank you, Katie and Crystal!!
If you are looking for a personalized fertility experience in the Charleston area, PREG is the right choice.

My husband and I came to PREG for a second opinion, and it was the best decision we made. Dr. Tarnawa explained our options and plan in great detail. Caroline was our nurse, and I cannot say enough good things about her. I looked forward to seeing her at every appointment, and she was always available to answer questions. At PREG, they truly care, which seems increasingly rare at clinics. Our baby is due January 26! I will always be grateful to PREG.

What an amazing team of doctors, nurses, and staff! We were devastated to learn that IVF was necessary for our second child, but Dr. Tarnawa made the journey easier with his kindness and compassion. Everyone was honest, answered every question, and helped address all our concerns. Katie also made the experience wonderful as our coordinator. To know her is to love her—she is amazing! I am grateful to the entire team every day.

I have had a wonderful experience as a patient at Preg since August 2024. Dr.Tarnawa has excellent bedside manner. He is kind, patient and very thorough. I also appreciate Leslie, Quinn, Alexis, Katie and Caroline who were always bright smiling faces in the Summerville office. The nursing staff was so prompt in responding to my questions. I am overall so impressed with the Preg team, they deserve all of the praise in the world. Infertility is very emotionally challenging and they were beyond supportive every step of the way!

After several unsuccessful rounds at another clinic, we came to PREG for a second opinion. Dr. Tarnawa was the first doctor to give us hope, and I will always be grateful. The care and compassion we received were unmatched. Dr. Tarnawa and his nurse Katie consistently provided excellent communication and genuinely cared about their patients. I am now holding my baby and cannot thank Dr. T and his staff enough!

I left this practice 13 months after beginning the journey. Unfortunately, there were many reasons. My first visit was pleasant, and I was excited to join the team.
Unfortunately, what they said and what they did were completely different.
I waited 3 months, pleading by email and phone for any attention so we could begin the process. I heard nothing from them. Finally, after three months of complete silence, they said they had been waiting for me to contact them.
I should have stopped going then.
It was not the first time they failed to respond.
Perhaps it would have been different if I were not a single woman, but I believe they exploited me because of it. They interviewed me about how much I earned and how many hours I worked. Then I received another $4,100 charge that they refused to explain or even discuss until I paid it, in addition to the initial $7,000 insurance payment. Insurance covered most of my costs here. When I asked for clarification, I was sharply told just to pay.
Wow.
I could continue, but I will not. If you want a company that respects you, treats your unborn child with dignity, and does not take your money—there was never a bill, only instructions to pay a certain amount—do not go here.
I am no longer a patient, yet I received multiple messages asking me to return, as well as rude messages about leaving.
Please do not make the mistake I made. Avoid these people and this company!

I cannot thank them enough for everything they did for us. They gave us our miracle baby, and I am nearly four months pregnant. They explained our options and the possible reasons conception had been delayed. It felt wonderful finally to have answers. I cannot recommend them enough. Thank you, thank you, thank you, thank you.

I never thought I would write this review. Theodore Roosevelt gave a speech called "The Man in the Arena." In many ways, it resembles this journey—an experience no one would choose as part of their life story. I am still in the arena, waiting to see whether God blesses us with this opportunity. It is an extremely vulnerable position, and I am profoundly grateful that in this vulnerability I found an outstanding team at PREG doing everything possible through treatment to give my husband and me the best chance. It feels as though we now have coaches and support in the arena. At every step, we have been treated with dignity, respect, and kindness. I believe we are receiving excellent care, though the final outcome is in God's hands. I understand how frightening it is to schedule an appointment and consider medical intervention, but I absolutely encourage you to make the brave choice and call for a consultation. The compassionate care we have received so far has exceeded my expectations.
