Exceptional People. Extraordinary Care.

  • There are no words to describe the dedication and commitment that Dr. Hajovsky shows toward her patients and in her profession.  She is truly a one-of-a-kind physician and person.  I strive to be as compassionate and provide the individual attention in my profession that Dr. Hajovsky bestows upon her patients.  Thank you for always being caring, supportive, and the best doctor that I have ever known.

  • I trust Dr. Hajovsky with my life and the lives of my babies. When I am in her office or in the hospital she makes me feel like I am her only patient. I admire how she loves her job, family and God with all her heart! I am extremely blessed and thankful to have her as my doctor.

  • For as long as I’ve known Dr. Hajovsky she has been the epitome of grace, poise, and strength in all areas of her life. I have never met someone that puts so much of herself into every one of her passions-being a mom as well as being an OBGYN-which has made having a family possible for me-and I can never thank her enough for that. I am privileged to call her my friend, physician, and role model.

  • When I came in as a new patient to Dr. Hajovksy, and it was found that I had a rare life-threatening pregnancy complication, she went above and beyond in taking care of me. I was admitted for an almost 2 month stay, and Dr. H. went to work researching my condition and making sure all the nurses, doctors, and staff were up on it. Her intelligence, diligence, and calm presence were instrumental in saving my daughter’s life and we are eternally grateful!

  • I am blessed to have you as my doctor and so thankful to you for being there for one of the hardest days of my life and the most precious day of my life, when we welcomed our sweet son into this world. Your smile and genuine care for each of your patients is appreciated. Thank you Dr. Hajovsky for choosing to make San Angelo your home.

  • Dr. Hajovsky has been blessed with an amazing gift that allows her to take care of her patients the way she does. I greatly appreciate her sincerity, trustworthiness, & genuine care that I have received through the years. I am forever grateful for her being a part of the most beautiful days of my life when she delivered my babies!

  • You’ve literally been a life saver more than once!!  Through all of my complicated deliveries, I would never have chosen to be under the care of anyone else in the world other than you. I’m thankful and blessed to have you as my doctor and friend whom I trust and admire.

  • Dr. Hajovsky is a doctor who truly cares about her patients. I trusted her through my entire fertility process and will always trust the decisions she makes in regards to my health. She is the reason I have 2 beautiful, healthy children, and I am forever grateful to her for that.

  • We have been blessed to have such a wonderful doctor and friend who has seen us through the highs and lows of five pregnancies and four babies. Thank you for the superior care, wise counsel, and comfort you have given to us. I literally cannot imagine bringing my babies into the world without you. You are the BEST!

  • I chose Dr. Hajovsky to take care of me during my pregnancy because I saw how much she cared for all her patients. At the time I was a nurse working with her patients and saw first-hand that she gave 100% of herself to see that they had the best care possible. She is smart, caring and very good at what she does. I wish saying thank you could express how grateful I am to call her my doctor and friend. You really are the best Dr. Hajovsky!

  • To me you are a physician with knowledge and skill beyond standards. You have a strong faith and strength along with compassion that goes above and beyond. To know you and work beside you are blessings that make me the nurse I am.
