Caleb Kallen, M.D, PhD

Dr. Kallen has been amazing through out my infertility journey. He is very caring and understanding and always made us feel comfortable and answered any questions we had. I always recommend Shady Grove to anyone I hear or know that is struggling through infertility!

I write this as I sit here with my SGF IVF baby. Before becoming a patient at SGF, I was terrified of needing to do IVF to grow a family. However, after our first appointment with Dr. Kallen, I felt so much more at ease. He told us matter-of-factly that my husband and I would have children. Hearing Dr. Kallen’s confidence made me trust him and gave my husband and I the faith we needed to move forward with fertility treatments. I could not recommend Dr. Kallen or Shady Grove Center City more. I will be back for baby #2 in the future! Best of luck to anyone finding themselves reading this review! You can do it!

When I first started out, The doctor was nice. My AMH was low. Since I went through chemo it was automatically recommended I do donor embryos or eggs. I was then told there would be a long wait for African American embryos. There was some sort of miscommunication between the doctors and the nurses. The nurse called to schedule me for a baseline, I went to the appointment the doctor asked me if I was matched with embryos, I stated I was not as I was told it was a few years wait. He then asked me what I scheduled an appointment for. I said well your nurse called and scheduled me so you should ask her. His demeanor was rude. They called me for a follow up and after that encounter I decided not to be a patient. I advise I wouldn’t be returning to their office anymore. I went to a different clinic and ended up with MY own eggs. They were PGT tested and were fine. I’m sure he isn’t a bad doctor, we just did not match and that’s ok. I’m very happy I decided to go else where before spending $30k when I could have just used my own eggs to begin with!

We were at Shady Grove Fertility (Chesterbrook) with Dr. Kallen for both of my rainbow miracle girls! There are not enough kind words to say about SGF, Dr. Kallen, and all the staff. Dr. Kallen always provided all my options for every step and stage of my journey. Sometimes it took me longer to process the information or my next steps. Dr. Kallen never pressured me to move in any particular direction, but did give me all the facts and outcomes possible. Dr. Kallen called personally with the difficult news, and shared in the excitement of the positive news. Thank you so Dr. Kallen and the amazing people of SGF.

I feel so incredibly lucky that I found myself in the care of Dr. Kallen and Shady Grove Fertility. After meeting several other doctors from big hospital systems, my husband and I felt discouraged, worried, also a little judged. From our first appointment with Dr. Kallen, we felt so much hope. This wasnt our fault, this was possible, and there was a very clear roadmap to get there. And from there, I was in the absolute best care I could ever have imagined. Dr Kallen is extraordinary at what he does, and the nurses and other doctors I got to meet during my time with SGF were equally as wonderful. I was so sad to leave them! I was referred to Dr. Kallen & SGF by a close friend and Ive recommended them to anyone who will listen.

Dr. Kallen is such and awesome Dr. Out of all the doctors I have met during my fertility journey Dr.Kallen made me feel like a human and he understood all my concerns. No matter how many questions I asked him he never seemed annoyed with me he even took time out of his personal time to call me and reassure me when my first transfer did not work. I love Dr. Kallen and he made it a true joy while I was at shady grove. He always went above and beyond his job to ensure my comfort and that I understood everything and if I needed help with anything he pointed me into the right direction. I would defitnley recommend Dr. Kallen to anyone that is going through fertility issues.

My husband and I first tried IVF while living overseas in Italy. Needless to say our first round of IVF left us unsuccessful and feeling discouraged. A few months later we moved to the states and spoke with several fertility clinics prior to speaking with Dr. Kallen at Shady Grove. When I spoke to Dr. Kallen I knew right away he was the doctor I wanted to work with. He answered all my questions and made me feel like this wasnt my fault and there was a light at the end of the tunnel.Throughout my IVF journey I could not have asked for a better team to get me through it. The nurses specifically Debbbie answered my questions promptly and did not make me feel for some of the things I asked. I even missed a dose and panicked, but Debbie called me on her day off and on a Saturday to reassure me everything was fine and explain what the next steps were. I had the privilege of going to both the Chesterbrook and City Central offices both of which were amazing people to work with and always polite.I am happy to announce with the help of Dr. Kallen and his amazing team at shady Grove we welcomed our baby girl on April 17, 2022!! This was a journey but we couldnt have made our dream become a reality without them. I 100% recommend Dr. Kallen and his team.

Dr. Kallen gave us hope for a family starting with our first appointment. Throughout our IVF journey Dr. Kallen remained engaged and enthusiastic. He called me personally with results- good and bad. Ultimately due to the care and knowledge of Dr. Kallen and the Shady Grove Team we are expecting our first child in April! I value my infertility experience because of the chance to recommend a passionate doctor like Dr. Kallen! If you are considering making an appointment at SGF - make the phone call, you won’t regret it.

I have been working with Dr. Kallen to help conceive for the past 3 years. We had quick success with our daughter and knew we wanted to work with him for our second baby.We are a part of the LGBT community and with Dr. Kallens guidance we were able to do reciprocal IVF so both my wife and I had a integral part in the process. It took us 3 tries to conceive our second baby and Dr. Kallen was supportive and empathetic every step of the way! We likely will want another child in the future, which will require another egg retrieval and transfer. We will not hesitate to continue working with Dr. Kallen to complete our family!

Dr. Kallen and the SGF team is everything I needed and more. They are knowledgeable, caring, understanding and patient. I feel like there is not enough thank yous that I can give to show our gratitude. I wish that SGF would have remained our team throughout our entire pregnancy to birth. Thats how much trust we had in them. The feeling we got when we found out that the IVF was a success is indescribable. They made sure to get us through the first 10 weeks of the pregnancy and made it easy to transition from them to my OB and hospital team. Always making sure we had great care. Now we have a beautiful baby girl and its thanks to this team for their guidance.

From the moment we met Dr. Kallen we knew we were in the right hands. Having to deal with infertility is hard but having a smart, supporting Doctor makes it a little easier. We are very grateful to have landed in his hands. Thanks to Dr. Kallen we are now almost 20 weeks pregnant with our little miracle. We couldnt have chosen a better clinic and have had a better doctor!

Dr. Kallen is so smart and thoughtful in the care he provides. He is reassuring and constantly has faith in the next steps he is offering. He is honest but so kind. We are so thankful we found him to care for us on our IVF journey. We came to him as a second opinion after many successful attempts at IUI and we were feeling lost and hopeless. In our very first conversation, I had tears in my eyes and trust in him. He truly cared about us as his patients and our journey to becoming parents.

Dr. Kallen and his associates are the finest professionals I have ever worked with. Being a nurse myself they went above and beyond any expectations I had. From the very beginning they were there for me during every upset and triumph to date. It was a long 8 months but I am happy to say I finally graduated their office and I am expecting a beautiful baby February 2022. Dr.Kallen I can’t thank you enough for all you have done for me. He was sure I would conceive and even though it took a little science, it finally happened! I also want to thank Hannah my nurse during this entire process. You were so kind and so helpful and always there for me whenever I needed and I am so grateful for everything you have done for me. I can’t recommend this group of professionals enough, top quality from start to finish.

Dr. Kallen made us comfortable from the very beginning. He answered all of our questions (we had A LOT!) without being impatient or frustrated. He walked us through every step of the way and was very matter-of-fact while having pleasant bedside manner. He made us feel we were in the best hands. And I cant say enough about his staff and their FAST responses on the patient portal. All in all, I 100% recommend Dr. Kallen and SGF! (SGF, Chesterbrook, PA location)

Thank you, Shady Grove Fertility — I begged my husband for a last hurrah with a different clinic in hopes that a miracle would happen & you made it happen. Thank you so much Dr. Kallen, Dr. Martin, & Nurse Debbie. And anyone else who helped us along this journey. Dr. Kallen said he was cautiously optimistic and that he thought he could make it work. Other clinics where we had second opinions weren’t as optimistic. Hope whispered try it one more time. We still cannot believe it! Dreams can come true. Thank you. Thank you. Thank you. We couldn’t be happier!! Baby snuggles are the best. Baby Michael is 1 week old today. I love being a mama & my husband loves being a dada. I will forever be grateful.

There are not enough words to express my gratitude for Dr.Kallen and the entire Shady Grove team.  Asthose struggling with fertility know, the journey is scary and filled with unknowns.  But from our first consultation at ShadyGrove, Dr. Kallen explained our options – and ultimately the entire IVF process– in detail in a calm and reassuring manner, making sure to answer all of our questionsalong the way.We began our care at the Philadelphia location where nurse Laura took care of us and made us feel like family. We ultimately changed locations (and nurses) because of COVID, but had a similarly wonderful experience with nurse Nikki.  At the Chesterbrook location, I was always greeted with a smile and words of encouragement by Nina at reception.  We were undergoing the process during thebeginning of COVID, when the world was especially uncertain.  I can’t describe how much the friendly faces and genuinely compassionate staff at Shady Grove helped ease the fears of both the IVF process and COVID.And now, the best part: I am posting this review with myabsolutely perfect two-week old daughter in my arms!  We are so unbelievably grateful to Dr. Kallen and Shady Grove for making her journey into the world possible.  We know we would not be here without the amazing help and support provided from Day 1 by our Shady Grove family!

I absolutely love SGF! Every doctor and every nurse I had was fantastic. I saw Dr. Kallen the most and have recommended many friends, coworkers and even random people who ask about my IVF story to him. He made me feel comfortable from day one and would personally call to check on me. A special thanks to him and his wonderful team for my amazing 15 month old boy 🤍

Dr. Kallen is incredibly knowledgeable, collaborative, and listens to his patients. He takes the time to go over everything in detail and always happy to answer any questions that come up. (And trust me, I had tons) He remains optimistic but doesn’t sugarcoat things, which I appreciate. Thanks to Dr. Kallen, we have a beautiful daughter and another on the way. I will forever be grateful for Dr. Kallen and the rest of the Shady Grove team!

The worst experience I could come across. I went to Dr. Kallen on December 4, 2018 for a check up ran some test that supposedly were covered by my insurance and now I am receiving bills for. I was then sent for an HSG exam that I was not properly briefed on as he let his assistant explain and she was just learning so she did not know anything. I went for the test as I trusted they knew what they were talking about and ended up in the hospital for 4 days. I called their emergency hotline and they responded a day after and I explained I was running high fevers and could not walk and they sent me to an urgent care that could not help me and I took myself to the ER and was immediately hospitalized and on observation because they though I may need surgery. Until this day Dr. Kallen has not called me, I called numerous times requesting information about my test what happened how I ended up in the hospital and no one could help me. I am now receiving collection letters and still do not know what happen to me or what my test results revealed. I would not recommend this place and definitely not Dr. Calen Kallen

I recently had a consult with Dr Kallen for ivf. Even though I was currently undergoing tx with another RE which I loved, they didnt offer a garuntee program which I needed for my own piece of mind. Dr Kallen spent approx. a full hour with me explaining all the ins and outs of tx. He was very patient and was very thorough with his information. I appreciated that he came out to the waiting room to greet me and take me back to his office and even though I was only there for a consult, due to where I was in my cycles he was able to do a scan and bloodwork that day. I also appreciated that he himself did my scan. I was then introduced to my own personal nurse Debbie who said she would be my nurse throughout the whole process and made me feel so comfortable and reassured me that i would be taken care of. Everyone was great there! I honestly didnt know what to expect and I really didnt want to leave my current RE but the experience I had with shady grove left me feeling confident that they would help my husband and I on this journey to conceive. I look forward to my future appointments with the staff at SGF!

So grateful for Dr. Kallen and the shady grove team. We delivered our first baby on 1/14/22. It was a great experience and would highly recommend Shady grove to anyone who is trying to conceive.

As a fertility doctor, youd think compassion would be a hallmark. Think again. The lack of professionalism, bedside manner and patient interest was abhorrent. From day 1, it was transparent that Dr. Kallens primary motivation was to find ways to instill fear in his patients in order to drive more revenue and monthly costs by taking advantage of patient vulnerability in such a sensitive situation. Shame on you.
